c# word excel text转html的方法
首先是预览图片，这个功能很好实现，无非就是创建一个html页面，嵌套一个<img>，为了限制图片类型，可以定义一个允许预览类型数组作为限制：
/// <summary>
/// 预览图片
/// </summary>
/// <param name="physicalPath"></param>
/// <param name="physicalDicPath"></param>
/// <returns></returns>
public string PreviewPic(string physicalPath, string physicalDicPath)
{
string imageName = Path.GetFileNameWithoutExtension(physicalPath);
string htmlName = imageName + ".html";
if (!File.Exists(physicalDicPath + htmlName))
{
FileStream fs = new FileStream(physicalDicPath + htmlName, FileMode.CreateNew);
StreamWriter sw = new StreamWriter(fs, Encoding.UTF8);
StringBuilder sb = new StringBuilder();
sb.Append(@"<!DOCTYPE html>
<html lang = 'zh-CN'><head>
<meta http - equiv = 'Content-Type' content = 'text/html; charset=UTF-8'>
<meta http - equiv = 'X-UA-Compatible' content = 'IE=edge'>
<meta name = 'viewport' content = 'width=device-width, initial-scale=1'>
<title>图片预览</title>
<style>
.content
{
width:80%;
height:auto;
margin:0 auto;
padding:10px 20px;
}
img{
width:80%;
height:auto;
margin: 10px 10%;
}
</style>
</head>");
sb.Append(@"<body><div class='content'>");
var TruePath = "http://" + HttpContext.Current.Request.Url.Authority + "/" + urlconvertor(physicalPath);
sb.Append(@"<img src='" + TruePath + "'/>");
sb.Append(@"</div>");
sb.Append(@"</body>");
sw.Write(sb.ToString()); //这里是写入的内容
sw.Flush();
sw.Close();
}
var resultRul = "http://" + HttpContext.Current.Request.Url.Authority + "/" + urlconvertor(physicalDicPath + htmlName);
return resultRul;
}
然后就是预览excel文件，这个微软为我们提供了现成的方法，打开nuget管理，安装Microsoft.Office.Interop.Excel；经测试xls和xlsx格式都可以成功解析，然后代码如下：
/// <summary>
/// 预览Excel
/// </summary>
/// <param name="physicalPath">文件物理路径</param>
/// <param name="physicalDicPath">文件夹物理路径</param>
/// <returns>生成页面链接</returns>
public string PreviewExcel(string physicalPath, string physicalDicPath)
{
string htmlName = Path.GetFileNameWithoutExtension(physicalPath) + ".html";
if (!File.Exists(physicalDicPath + htmlName))
{
Microsoft.Office.Interop.Excel.Application application = null;
Microsoft.Office.Interop.Excel.Workbook workbook = null;
application = new Microsoft.Office.Interop.Excel.Application();
object missing = Type.Missing;
object trueObject = true;
application.Visible = false;
application.DisplayAlerts = false;
workbook = application.Workbooks.Open(physicalPath, missing, trueObject, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing, missing);
//Save Excel to Html
object format = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml;
String outputFile = Path.GetDirectoryName(physicalPath) + "\\" + htmlName;
workbook.SaveAs(outputFile, format, missing, missing, missing,
missing, XlSaveAsAccessMode.xlNoChange, missing,
missing, missing, missing, missing);
workbook.Close();
application.Quit();
}
var resultRul = "http://" + HttpContext.Current.Request.Url.Authority + "/" + urlconvertor(physicalDicPath + htmlName);
return resultRul;
}
最后就是word的预览了，word的话有两个常见格式：doc，docx；在测试该方法的时候，打开doc格式的word，每次都会弹出转换格式的弹窗，上网查了一下，原来的
Documents.Open()
方法的第二个参数是：真正显示转换文件对话框，如果该文件不是Microsoft Word格式。所以我们只需要将 ConfirmConversions设置为false即可规避这个问题；代码如下：
/// <summary>
/// 预览Excel
/// </summary>
/// <param name="type">文件格式</param>
/// <param name="physicalPath">文件物理路径</param>
/// <param name="physicalDicPath">文件夹物理路径</param>
/// <returns>生成页面链接</returns>
public string PreviewWord(string physicalPath, string physicalDicPath)
{
string htmlName = Path.GetFileNameWithoutExtension(physicalPath) + ".html";
if (!File.Exists(physicalDicPath + htmlName))
{
Microsoft.Office.Interop.Word._Application application = null;
Microsoft.Office.Interop.Word._Document doc = null;
application = new Microsoft.Office.Interop.Word.Application();
object missing = Type.Missing;
object trueObject = true;
object falseObject = false;
application.Visible = false;
application.DisplayAlerts = WdAlertLevel.wdAlertsNone;
doc = application.Documents.Open(physicalPath, falseObject, trueObject, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);
object format = format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatHTML;
String outputFile = Path.GetDirectoryName(physicalPath) + "\\" + htmlName;
doc.SaveAs(outputFile, format, missing, missing, missing,
missing, missing, missing,
missing, missing, missing, missing);
doc.Close();
application.Quit();
}
var resultRul= "http://"+HttpContext.Current.Request.Url.Authority +"/"+ urlconvertor(physicalDicPath + htmlName);
return resultRul;
}
最后是预览text，这个实现思想和预览图片是一样的，读取文档内容，填充到html页面上，代码如下：
/// <summary>
/// 预览Txt
/// </summary>
/// <param name="physicalPath">文件物理路径</param>
/// <param name="physicalDicPath">文件夹物理路径</param>
/// <returns>生成页面链接</returns>
public string PreviewTxt(string physicalPath, string physicalDicPath)
{
FileStream aFile = new FileStream(physicalPath, FileMode.Open);
//暂时不知道为什么获取的编码方式会导致读取的内容为空
//Encoding codeType = GetType(aFile);
StreamReader sr = new StreamReader(aFile, Encoding.GetEncoding("GB2312"));
var content= sr.ReadToEndAsync().Result.Replace("\r\n","</br>");
string htmlName = Path.GetFileNameWithoutExtension(physicalPath) + ".html";
if (!File.Exists(physicalDicPath + htmlName))
{
FileStream fs = new FileStream(physicalDicPath + htmlName, FileMode.CreateNew);
StreamWriter sw = new StreamWriter(fs,Encoding.UTF8);
StringBuilder sb = new StringBuilder();
sb.Append(@"<!DOCTYPE html>
<html lang = 'zh-CN'><head>
<meta http - equiv = 'Content-Type' content = 'text/html; charset=UTF-8'>
<meta http - equiv = 'X-UA-Compatible' content = 'IE=edge'>
<meta name = 'viewport' content = 'width=device-width, initial-scale=1'>
<title>文本预览</title>
<style>
.content
{
width:60%;
height:auto;
margin:0 auto;
border:1px solid #333;
padding:10px 20px;
}
</style>
</head>");
sb.Append(@"<body><div class='content'>");
sb.Append(@"<p>");
sb.Append(content);
sb.Append(@"</p></div>");
sb.Append(@"</body>");
sw.Write(sb.ToString()); //这里是写入的内容
sw.Flush();
sw.Close();
}
sr.Close();
var resultRul = "http://" + HttpContext.Current.Request.Url.Authority + "/" + urlconvertor(physicalDicPath + htmlName);
return resultRul;
}
