<form id= "Form1 " method= "post " runat= "server " enctype= "multipart/form-data ">

出什么错？？错误提示呢？？贴出来look look
[解决办法]
贴个我从前写的代码，用的FileUpload控件，限定wmv/wma，如果不加限定，去掉contenttype的if就行了。
string str = Server.MapPath( ". ") + "\\source\\ " + Path.GetFileName(myUpLoad.PostedFile.FileName); ;
if (myUpLoad.HasFile == true)
{
string fileContentType = myUpLoad.PostedFile.ContentType;
if (fileContentType == "audio/x-ms-wma " || fileContentType == "video/x-ms-wmv ")
{
if (File.Exists(str) == false)
try
{
myUpLoad.SaveAs(str);
}
catch (Exception es)
{
lblInfo.Text = es.Message;
}
else lblInfo.Text = "File already exists. ";
}
else lblInfo.Text = "It must be a wma or wmv file. ";
}
