如已绑定过数据源: DataTable dt = (dataGridView1.DataSource as DataTable) 如未绑定过数据源: public DataTable GetDgvToTable(DataGridView dgv) { DataTable dt = new DataTable(); // 列强制转换 for (int count = 0; count < dgv.Columns.Count; count++) { DataColumn dc = new DataC

步骤: 一.前台JS取HtmlTable数据,根据设定的分隔符把数据拼接起来 <!--导出Excel--> <script type="text/javascript"> //导出Excel function exportExcel() { var data = ""; $("#divRptTable").find("table").find("tr").each(function

list转换成DataTable类如下: public static DataTable ToDataTable<T>(this IList<T> datas) { DataTable dt = new DataTable(); Type type = typeof(T); PropertyInfo[] properties = type.GetProperties(); List<KeyValuePair<PropertyInfo, ExportFieldAttrib

领导让在存储过程中批量添加数据,找出效率最高的,我看到后台代码后,发现可以将list<对象>转换成DataTable,把DataTable转换成参数传入存储过程实现批量插入数据,知道还有其他的方法,不过这个方法已经实现,就写一下了: 1.创建表. CREATE TABLE [dbo].[person]( [ID] [,) NOT NULL, [Name] [nvarchar]() NULL, [Pwd] [nvarchar]() NULL, [Age] [int] NULL ) 2.创建表值参

在数据处理的时候,我们会Excel(包含2003.2007.2010等)转换成DataTable,以便进一步操作 1.怎么访问Excel文件呢?我们可以通过OLEDB接口访问,如下: private string GetConStr(string ExcelPath) { string path = ExcelPath; if (!File.Exists(path)) return null;string str2 = Path.GetExtension(path).ToLower(); if

  c# datarow[] 转换成 datatable, List<T> 转datatable DdataRow[]转成Datatable private DataTable ToDataTable(DataRow[] rows) { ) return null; DataTable tmp = rows[].Table.Clone(); // 复制DataRow的表结构 foreach (DataRow row in rows) { tmp.ImportRow(row); // 将Data

前面写了一篇List<T>转换成DataTable,这里主要是完善了前面的代码. 同样使用了emit,我把代码整理后上传了git. 另外增加了特性的设计. 设计了三类特性ColumnType(列类型映射),DataField(列名称映射),NoColumn(没有对应的列,忽略该属性) 都是使用IList<T>扩展方法调用. 附上源码地址: https://github.com/jinyuttt/ListToDataTable.git

前段时间通过网上查找,使用emit将Datatable,DataReader转换成List<T>了.这是从数据库到展示. 但是最近整理Hikari(我写的数据库连接池),发现c#里面数据库客户端驱动一般会提供一个BulkCopy的类,一般接口是DataTable,可以批量插入.所以又研究了如何把List<T>转DataTable. 一般方法是全部反射,我就不说了.这里只说emit,记录下下次用. 这里创建动态方法(委托)有个范围问题.我举个例子 假如有Pseron类. public
