.NET环境下上传和下载Word文件

一、上传Word文档或者其他文档

1、简单地上传文件的web服务方法如下

[WebMethod]

        public void UploadFile()

        {

            using (TransactionScope ts = new TransactionScope())

            {

                var postedFiles = Request.GetHttpFiles();

                var guid = postedFiles[].Save(HttpContext.Current, Database);

                //其他操作可以在此处添加

                Response.Write("<html><body>{ success: true, guid: '" + guid.GetFilePath(Database) + "' }</body></html>");

                var info = string.Format("{0}上传文件，GUID：{1}", User.Name, guid);

                BusinessLog.Write(User, Request.UserHostAddress, info, Database);

                ts.Complete();

            }

        }

2、调用函数的类：以上web服务用到的FileUpLoad和GUID相关的代码包含在HttpPostedFileExtension.cs文件中

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Web;

using System.IO;

using Ipms.Server.Business;

using Ipms.Server.Business.Common;

namespace Ipms.Server.UI.MISExtension

{

    /// <summary>

    /// 上传文档的相关扩展

    /// </summary>

    public static class HttpPostedFileExtension

    {

        /// <summary>

        /// 上传文档保存路径

        /// </summary>

        public const string POSTED_FILE_ROOT_DIRECTORY = @"/IpmsDocument\";

        /// <summary>

        /// 保存上传文件

        /// </summary>

        /// <param name="postedFile"></param>

        /// <param name="context"></param>

        /// <param name="database"></param>

        /// <returns></returns>

        public static Guid Save(this HttpPostedFile postedFile, HttpContext context, IDatabase database)

        {

            string directory = context.Server.MapPath(POSTED_FILE_ROOT_DIRECTORY);

            if (!Directory.Exists(directory))

                Directory.CreateDirectory(directory);

            string fileName = Path.GetFileName(postedFile.FileName);

            string fileType = fileName.Substring(fileName.LastIndexOf(".") + );

            Resource resource = new Resource();

            resource.ResourceName = fileName;

            resource.Type = fileType;

            resource.Save(database);

            string newFileName = resource.Guid + "." + fileType;

            string filePath = directory + newFileName;

            if (File.Exists(filePath))

                File.Delete(filePath);

            postedFile.SaveAs(filePath);

            return resource.Guid;

        }

        /// <summary>

        /// 取得文件路径

        /// </summary>

        /// <param name="guid"></param>

        /// <param name="database"></param>

        public static string GetFilePath(this Guid guid, IDatabase database)

        {

            var server = HttpContext.Current.Server;

            Resource resource = database.Resources.GetByGuid(guid);

            if (resource == null)

                throw new ArgumentNullException("guid");

            string fileName = POSTED_FILE_ROOT_DIRECTORY + "/" + guid + "." + resource.Type;

            return fileName;

        }

    }

}

二、导出word文档

1、导出word文档的代码如下，下面的代码包含了来自两个模板的word文档的下载和导出，其原理为读取相应的word模板，找到标签或者表格，将数据库内的字段填入：

       [WebMethod]

        public void s()

        {

            try

            {

                var direc = HttpContext.Current.Server.MapPath(HttpPostedFileExtension.POSTED_FILE_ROOT_DIRECTORY);

                //@"D:\member\wanghuanjun\Ipms\Solution\0.3\Ipms.WebSite\IpmsDocument\

                var templateName = direc + "大型精密仪器设备论证一览表_模板.doc";

                Microsoft.Office.Interop.Word.ApplicationClass wordApp;

                Microsoft.Office.Interop.Word.Document wordDocument = new Microsoft.Office.Interop.Word.Document();

                object Obj_FileName = templateName;

                object Visible = false;

                object ReadOnly = false;

                object missing = System.Reflection.Missing.Value;

                wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

                Object Nothing = System.Reflection.Missing.Value;

                wordDocument = wordApp.Documents.Open(ref Obj_FileName, ref missing, ref ReadOnly, ref missing,

                    ref missing, ref missing, ref missing, ref missing,

                    ref missing, ref missing, ref missing, ref Visible,

                    ref missing, ref missing, ref missing,

                    ref missing);

                wordDocument.Activate();

                Microsoft.Office.Interop.Word.Table wordTable = wordDocument.Tables[];

                var Iid = Request.GetInt("tastItemID");

                var memI = Database.ConstructTaskItems.SingleOrDefault(cti => cti.ID == Iid);

                wordDocument.Bookmarks.get_Item("Unit").Range.Text = memI.ConstructPlanItem.MemberApplyItem.MemberApply.Project.College.Name;

                wordDocument.Bookmarks.get_Item("DeviceManager").Range.Text = memI.ConstructPlanItem.MemberApplyItem.MemberApply.Member.Name;

                wordDocument.Bookmarks.get_Item("Manager").Range.Text = memI.ConstructPlanItem.MemberApplyItem.MemberApply.Project.Manager.Name;

                wordDocument.Bookmarks.get_Item("DeviceNumber").Range.Text = memI.ConstructPlanItem.DeviceNumber;

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.DeviceName;

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.EnglishName;

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.Quantity.ToString();

                wordTable.Cell(, ).Range.Text = (memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.UnitPrice / ).ToString() + "元";

                wordTable.Cell(, ).Range.Text = ((memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.UnitPrice * memI.ConstructPlanItem.MemberApplyItem.Quantity) / ).ToString() + "元";

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.NecessityAnalysis;

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.MainSpec;

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.AccessorySpec;

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.Environment;

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.Consumables;

                wordTable.Cell(, ).Range.Text = memI.ConstructPlanItem.MemberApplyItem.ApplyDevice.Power;

                var deviceMaths = Database.DeviceMatchs.Where(dm => dm.ApplyDevice == memI.ConstructPlanItem.MemberApplyItem.ApplyDevice);

                var temp = ;

                //设备选型

                if (deviceMaths.Count() >  && deviceMaths.Count() <= )

                    foreach (var item in deviceMaths)

                    {

                        if (item != null)

                        {

                            wordTable.Cell(,  + temp).Range.Text = item.MarketDevice.MarketDeviceName;

                            wordTable.Cell(,  + temp).Range.Text = item.MarketDevice.Model;

                            var deviceSupplier = Database.DeviceSuppliers.Where(ds => ds.DeviceMatch == item).FirstOrDefault();

                            if (deviceSupplier != null)

                            {

                                wordTable.Cell(,  + temp).Range.Text = deviceSupplier.Supplier.Name;

                                wordTable.Cell(,  + temp).Range.Text = deviceSupplier.ContactPerson + ":" + deviceSupplier.ContactPhone;

                                wordTable.Cell(,  + temp).Range.Text = (deviceSupplier.Price / ).ToString() + "元";

                                wordTable.Cell(,  + temp).Range.Text = deviceSupplier.PriceSource ==  ? "供应商" : "网络";

                            }

                        }

                        temp += ;

                    }

                var extrals = Database.DeviceExtramurals.Where(de => de.ApplyDevice == memI.ConstructPlanItem.MemberApplyItem.ApplyDevice).ToList();

                if (extrals.Count() >  && extrals.Count() <= )

                {

                    if (extrals.Count() >= )

                    {

                        for (int i = ; i < extrals.Count(); i++)

                        {

                            wordTable.Cell( + i, ).Range.Text = (extrals[i].UnitPrice/).ToString()+"元";

                        }

                    }

            //关闭wordDoc文档对象

            wordDocument.Close(ref Nothing, ref Nothing, ref Nothing);

            wordDocument = null;

            //关闭wordApp组件对象

            wordApp.Quit(ref Nothing, ref Nothing, ref Nothing);

        }

2、以上使用标签机制来完成的word文档的下载和内容的导出，因此需要有一个word模板，之后这个模板内应设置相应的标签或者表格内容

在设置word标签和表格内容的时候，首先使用word2010打开模板，之后选择“开发工具”选项卡，如果这个选项卡选择之后，内部的小控件是不可编辑的，则需要进行相应的设置，然后添加标签或者查看表格的属性就可以完成模板的设置。
