搞了快一个小时网上的代码缺这缺那的，这个我自己改好的，希望能帮到大家，前台就是拉个gridvidw，贴后台代码给大家看看
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.GridView1.DataSource = ds.VFoodReport.ToList();
this.GridView1.DataBind();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.Charset = "GB2312";
Response.AppendHeader("Content-Disposition", "attachment;filename=Report.xls");
// 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！！！
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.GridView1.RenderControl(oHtmlTextWriter);
Response.Output.Write(oStringWriter.ToString());
Response.Flush();
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{ }
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[1].Attributes.Add("style", "vnd.ms-excel.numberformat:@;");
}
}
我这里测试通过没有问题了 有什么问题大伙再继续讨论
