asp.net 上传控件

注册控件：
<%@ Register TagPrefix="fup" Namespace="OboutInc.FileUpload" Assembly="FileUpload" %>

调用控件：
<form runat="server" id="form1">
<input type="file" name="myFile1" /><br/>
<input type="file" name="myFile2" /><br/>
<input type="file" name="myFile3" /><br/>
<ASP:LinkButton runat="server" text="上传" />
     
<ASP:LinkButton runat="server" text="取消" onClientClick="Cancel(); return false;" /><br/>
<br/>
<fup:FileUploadProgress 
OnClientProgressStopped   = "function(){alert('文件已上传');}"
OnClientProgressStarted   = "Clear"
OnClientServerException   = "ServerException"
ShowUploadedFiles         = "true"
runat                     = "server"
ID                        = "uploadProgress"
InnerFiles                = "true"
StyleFile                 = "fup_styles/myStyle.css"
LocalizationFile="fup_localization/en.xml" />

后台代码：
OboutFileCollection files = uploadProgress.Files;           
for(int i=0; i < files.Count; i++)
{
OboutPostedFile file = files[i];
file.SaveAs(MapPath("~/Uploaded/"+Path.GetFileName(file.FileName)));
}
