DataGrid输出文件的几种方法

从DataGrid输出文件到Excel、Word和Text文件使用这样输出还是很高效的。

1、输出到Excel：

Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
myDataGrid.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();

2、输出到Word文档

Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.doc");
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.word";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
myDataGrid.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();

3、输出到文本文件

Database db = DatabaseFactory.CreateDatabase();
DBCommandWrapper selectCommandWrapper = db.GetStoredProcCommandWrapper("sp_GetLatestArticles");

DataSet ds = db.ExecuteDataSet(selectCommandWrapper);

StringBuilder str = new StringBuilder();

for(int i=0;i<=ds.Tables[0].Rows.Count - 1; i++)
{
for(int j=0;j<=ds.Tables[0].Columns.Count - 1; j++)
{
str.Append(ds.Tables[0].Rows[i][j].ToString());
}
str.Append("<BR>");
}

Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.txt");
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.text";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
Response.Write(str.ToString());
Response.End();
