代碼如下:
protected void Excel_Click(object sender, EventArgs e)
{
Response.Charset = "UTF-8";
Response.ClearContent();
Response.Clear();
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.HeaderEncoding = System.Text.Encoding.UTF8;
Response.AddHeader("content-disposition", "attachment; filename=MyExpress.xls");
Response.ContentType = "application/excel";
System.IO.StringWriter sw = new System.IO.StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
// turn off paging
GridView1.AllowPaging = false;
dataBind();
GridView1.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
// turn the paging on again
GridView1.AllowPaging = true;
dataBind();
}

關(guān)鍵:
代碼如下:
Response.Charset = "UTF-8";//添加編碼格式
Response.ClearContent();
Response.Clear();
Response.ContentEncoding = System.Text.Encoding.UTF8;//表格內(nèi)容添加編碼格式
Response.HeaderEncoding = System.Text.Encoding.UTF8;//表頭添加編碼格式

上邊如果解決不了還可以用
代碼如下:
Response.ClearContent();
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=sumlate.xls");
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
Response.ContentType = "application/excel";
System.IO.StringWriter sw = new System.IO.StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
if (GridView2.Rows.Count > 0)
{
GridView2.RenderControl(htw);
}
else
{
GridView1.RenderControl(htw);
}
Response.Write(sw.ToString());
Response.End();

關(guān)鍵：
代碼如下:
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

注意觀察，主要原因其實(shí)就是編碼格式問題。

現(xiàn)在就能防止導(dǎo)出時(shí)候亂碼問題了
