复制代码 代码如下:

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();

}

关键:

复制代码 代码如下:

Response.Charset = "UTF-8";//添加编码格式

Response.ClearContent();

Response.Clear();

Response.ContentEncoding = System.Text.Encoding.UTF8;//表格内容添加编码格式

Response.HeaderEncoding = System.Text.Encoding.UTF8;//表头添加编码格式

上边如果解决不了还可以用

复制代码 代码如下:

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();

关键：

复制代码 代码如下:

Response.Charset = "GB2312";

Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

注意观察，主要原因其实就是编码格式问题。

现在就能防止导出时候乱码问题了
