System.Text.Encoding.UTF8; 出现乱码

[lixiuxiu_1314]

我做的功能是导出Excel
代码如下
protected void Button1_Click(object sender, EventArgs e)
{
string Year = System.DateTime.Now.Year.ToString();
string Month = System.DateTime.Now.Month.ToString();
string Day = System.DateTime.Now.Day.ToString();
string DateString = Year + "-" + Month + "-" + Day;

ExportToExcel("application/ms-excel", DateString + ".xls");
}
public void ExportToExcel(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
//System.Text.Encoding.UTF8;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
MedicineList.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}

一般的都不会出错 今天突然运行处一条乱码数据 求解 是因为什么

之前也出现过，把你的文档向下兼容保存一下

除非不得已，否则不要使用gb2312。
