关于“下载”的源码
我想要一个.NET关于“下载”的源代码，简单实用--------------------编程问答-------------------- 关于下载？
什么意思？ --------------------编程问答-------------------- 难道是传说中的“下载”···

/// <summary>
/// 下载文件

/// <param name="path">文件路径</param>
public static void DownLoad(string path)
{
System.IO.FileInfo fi = new System.IO.FileInfo(path);
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.Buffer = false;
HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(path)));
HttpContext.Current.Response.AppendHeader("Content-Length", fi.Length.ToString());
HttpContext.Current.Response.ContentType = "application/octet-stream";
HttpContext.Current.Response.WriteFile(path);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
#region 下载服务器上的文件--------------------编程问答--------------------
