怎样调用迅雷来下载？

Question

这个是自己写的。只能调用系统自带的下载。我想知道怎么可以调用迅雷来下载？
  if (File.Exists(strFilePath))
            {
                //限制下载速度 
                //FC.DowndLoadFile(this.Page.Request, this.Page.Response,new System.IO.FileInfo(strFilePath).Name.ToString(), strFilePath, 204800);
                //没有限制下载速度
                System.IO.FileInfo file = new System.IO.FileInfo(strFilePath);
                Response.Clear();
                Response.ClearHeaders();
                Response.Buffer = true;
                Response.ContentType = "application/octet-stream";
                Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(file.Name, System.Text.Encoding.UTF8));
                Response.AppendHeader("Content-Length", file.Length.ToString());
                Response.WriteFile(file.FullName);
                Response.Flush();
                //下载次数++
                FC.UpdateDownLoads(Convert.ToInt32(Session["fileID"]));
                //重新绑定数据
                DLDownLoadBind();
                Response.End();
            }

Answer 1

添加Download.aspx页。FileStream f= new FileStream("", FileMode.Open);  
byte[] buffer = new byte[f.Length];  
f.Read(buffer, 0, buffer.Length);  
f.Close();  
Response.ContentType = "application/octet-stream";  
Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode("", System.Text.Encoding.UTF8));  
Response.BinaryWrite(buffer);  
Response.Flush();  
Response.End();   参考

//TransmitFile实现下载
    protected void Button1_Click(object sender, EventArgs e)
    {
        /*
         微软为Response对象提供了一个新的方法TransmitFile来解决使用Response.BinaryWrite
         下载超过400mb的文件时导致Aspnet_wp.exe进程回收而无法成功下载的问题。
         代码如下：

        Response.AddHeader("Content-Disposition", "attachment;filename=z.zip");
        string filename = Server.MapPath("DownLoad/z.zip");

Answer 4

FullFileName ，文件的物理路径
public void FileDownloadByFullName(string FullFileName)
        {
            System.IO.FileInfo DownloadFile = new System.IO.FileInfo(FullFileName);
            System.Web.HttpContext.Current.Response.Clear();
            System.Web.HttpContext.Current.Response.ClearHeaders();
            System.Web.HttpContext.Current.Response.Buffer = false;
            System.Web.HttpContext.Current.Response.ContentType = "application/octet-stream";
            System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(DownloadFile.Name, System.Text.Encoding.UTF8));
            System.Web.HttpContext.Current.Response.AppendHeader("Content-Length", DownloadFile.Length.ToString());
            System.Web.HttpContext.Current.Response.WriteFile(DownloadFile.FullName);
            System.Web.HttpContext.Current.Response.Flush();
            System.Web.HttpContext.Current.Response.End();
        }
