asp.net 导出Execl 解决中文名乱码

1.导出为cvs

首先要获取一连串的string类型的字符串,然后确定导出格式....

先获取表格的头，这个header不管你是固定还是动态，每个字段后面加一个","，用来表示一列；到最后换行时加Environment.NewLine；例如：

　　　　ArrayList list = new ArrayList();
                        list.Add("xxx");
                        list.Add("xx");
                        list.Add("xx");
                        list.Add("xx");
                        list.Add("xxx");
                        list.Add("xx");
                        list.Add("xx");
                        list.Add("xx");
                        list.Add("xxxx");

string[] saleHeaders = (string[])list.ToArray(typeof(string));
                        temp = saleWriteOffHtmlStr(saleDt, saleHeaders);

　　byte[] buffer = System.Text.Encoding.UTF8.GetBytes(temp.ToString());
                        byte[] outBuffer = new byte[buffer.Length + 3];
                        outBuffer[0] = (byte)0xEF;
                        outBuffer[1] = (byte)0xBB;
                        outBuffer[2] = (byte)0xBF;
                        Array.Copy(buffer, 0, outBuffer, 3, buffer.Length);
                        Response.Write(Encoding.UTF8.GetString(outBuffer));
　　Response.Buffer = true;
            Response.AddHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode("销售数据") + ".csv;");
            Response.Charset = "utf-8";
            Response.ContentType = "text/csv";　　　　　　　　　　　　

public string saleWriteOffHtmlStr(DataTable dt, string[] headers)

{
       string htmlstr = "";

　　　　foreach (string s in headers)
            {
                htmlstr += s.ToString().Replace(',', '，') + ",";
            }
            htmlstr = htmlstr.Substring(0,htmlstr.Length-1) + Environment.NewLine;

　　　　foreach (DataRow dr in dt.Rows)
            {
                htmlstr += dr["Base_tabletNumber"].ToString().Replace(',', '，') + ",";

　　　　　　.......

　　　　　　htmlstr += Environment.NewLine;

　　　　}

　　　　return htmlstr;

}

2.导出为xls

HttpResponse resp;
                        resp = Page.Response;
                        resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
                        resp.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode("销售表", System.Text.Encoding.UTF8) + ".xls;");
                        resp.Write(temp);
                        temp = "";
                        resp.End();

public string saleWriteOffHtmlStr(DataTable dt, string[] headers)
        {

            string htmlstr = "";
            foreach (string s in headers)
            {
                htmlstr += s.ToString().Replace(',', '，') + "\t";
            }
            htmlstr = htmlstr.Substring(0, htmlstr.Length - 1) + "\n";
            foreach (DataRow dr in dt.Rows)
            {
                htmlstr += dr["Base_tabletNumber"].ToString().Replace(',', '，') + "\t";
.....................
.....................
 htmlstr += "\n";
            }
            return htmlstr;
        }

System.Web.HttpUtility.UrlEncode("销售表", System.Text.Encoding.UTF8)  处理文件名乱码问题
