#问题：客户端为ie或Firefox，服务端为asp.net时，下载文件名中包含中文汉字时，下载下来的文件的文件名是乱码；
#解决方案：
示例代码：下载名称中带汉字的文件；
public void ProcessRequest(HttpContext context)
2 {
string action = context.Request["action"].ToString();
if (action == "download")
{
string fileName = "资源统计详细信息.txt";//客户端保存的文件名
string filePath = context.Server.MapPath("资源统计详细信息.txt");//服务端文件路径 //以字符流的形式下载文件
FileStream fs = new FileStream(filePath, FileMode.Open);
byte[] bytes = new byte[(int)fs.Length];
fs.Read(bytes, , bytes.Length);
