HttpResponse resp = System.Web.HttpContext.Current.Response;

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

resp.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlPathEncode(FileName));

resp.Write(sb.ToString());

方法二：

Console.WriteLine(sb.ToString());

FileStream aFile = new FileStream("D:\\temp\\lintest.dat", FileMode.OpenOrCreate);

StreamWriter sw = new StreamWriter(aFile);

sw.Write(sb.ToString());

Response.Buffer = true;

Response.ContentType = "text/richtext";

Response.AddHeader("content-disposition", "attachment; filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8) + ";size=0");

Response.Write(sb.ToString());

Response.Flush();
