上传文件：

 string upFileName = localRoot + shareOriginalPath + "/" + saveName + ext;                

// 判断存放原文件的路径是否存在                

if (Directory.Exists(localRoot + shareOriginalPath) == false)//如果不存在就创建file文件夹                

 {                   

  Directory.CreateDirectory(localRoot + shareOriginalPath);             

  }

UploadFile.PostedFile.SaveAs(upFileName);

 protected void btn_submit_Click(object sender, EventArgs e)     {        

 string filename = UpLoadFile(upFile, "upload");       

  if (!string.IsNullOrEmpty(filename))      

   {            

 ClientScript.RegisterClientScriptBlock(this.GetType(), "uploadfile", "window.top.prvimage('" + filename + "')", true);       

  }    

 }

 

function prvimage(upValue) {     var upHFileUrl = document.getElementById("HFileUrl");     upHFileUrl.value = upValue;     var Pic = document.getElementById('frameUploadPic').contentWindow.upFile();     if (Pic != "") {         document.getElementById('frameUploadPic').contentWindow.Upload();         var end = upValue.substring(upValue.lastIndexOf(".") + 1);         end = end.substring(0, end.indexOf("|"));         if (end == "swf" || end == "flv" || end == "mp4" || end == "SWF" || end == "FLV" || end == "MP4") {             document.getElementById('frameUploadPic').contentWindow.Upload();         }     }     else {         //让按钮事件进行提交         __doPostBack($('#hidUid').val(), "");     }     return false; }
