asp.net导出excel，excel是乱码

[ibilly77]

我要将gridview中的数据导出到一张excel中，但是导出后发现居然是乱码的，并且只有一行，想请问下高手们我这是什么情况

难道是excel还要先设置？

下面是我的后台代码：

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.SqlClient;
using System.Drawing;
using System.IO;
using System.Text;

namespace WebApplication5
{
    public partial class outexcel : System.Web.UI.Page
    {
        SqlConnection sqlcon;
       // SqlCommand sqlcom;
        string strCon = "Data Source=(local);Database=drop;Uid=sa;Pwd=sa123456";
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                bind();

            }
        }
        public void bind()
        {
            string sqlstr = "select  id,createdate from test01";
            sqlcon = new SqlConnection(strCon);
            SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
            DataSet myds = new DataSet();
            sqlcon.Open();
            myda.Fill(myds, "test01");
            GridView1.DataSource = myds;
            GridView1.DataKeyNames = new string[] { "id" };
            GridView1.DataBind();
            sqlcon.Close();
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            Export("application/ms-excel", "name.xls");
        }

        private void Export(string FileType, string FileName)
        {
            Response.Charset = "GB2312";
            Response.ContentEncoding = System.Text.Encoding.UTF7;
            Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
            Response.ContentType = FileType;
            this.EnableViewState = false;
            StringWriter tw = new StringWriter();
            HtmlTextWriter hw = new HtmlTextWriter(tw);
            GridView1.RenderControl(hw);
            Response.Write(tw.ToString());
            Response.End();
        }
        public override void VerifyRenderingInServerForm(Control control)
        {
        }

    }
}

CultureInfo cul;
        StringWriter oStringWriter;
        HtmlTextWriter oHtmlTextWriter;
        string strFileName = DateTime.Now.ToString();

        Response.Clear();
        Response.Buffer = true;

        //Response.AppendHeader("Content-Disposition", "attachment;filename=" + strFileName + ".xls");
        Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.xls");

        Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");//设置输出流为简体中文  
        Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。  
        //Me.EnableViewState = True  

        cul = new CultureInfo("ZH-CN", true);
        oStringWriter = new StringWriter(cul);
        oHtmlTextWriter = new HtmlTextWriter(oStringWriter);
        gridview1.RenderControl(oHtmlTextWriter);//tblOrder是需要输出的表格的ID;如果是输出datagrid的内容那就替换成datagrid的ID就可以了.  
        Response.Write(oStringWriter.ToString());
        Response.End();

try
{
//定义文档类型、字符编码

Response.Clear();
Response.Buffer = true;

Response.Charset = "gb2312";

Charact.Charact c = new Charact.Charact();
string tempname = c.GetAllPYLetters(DropDownList3.Text) + DateTime.Now.ToString("yyyyMMdd");

Response.AppendHeader("Content-Disposition", "attachment;filename=" + tempname + ".xls");

Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");

Response.ContentType = "application/ms-excel";

this.EnableViewState = false;
//　定义一个输入流
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

box.RenderControl(oHtmlTextWriter);

//this 表示输出本页，你也可以绑定datagrid,或其他支持obj.RenderControl()属性的控件
Response.Write(oStringWriter.ToString());
Response.End();
}
catch
{
return;

我导出的文件在office03和wps中显示的就算不是乱码，但是到office07中显示为乱码，请问有什么解决方法吗？还是说03和07的导出方式是不一样的？

[xiaofeixia__9999]

Response.ContentEncoding = System.Text.Encoding.UTF7;
是UTF8吧？
