多文件上传

Code
private void upMorefile()
{

HttpFileCollection files = Request.Files;

System.Text.StringBuilder strMsg = new System.Text.StringBuilder("上传的文件信息分别为：<hr color=red>");
int fileCount;

try
{
for (fileCount = 0; fileCount < files.Count; fileCount++)
{

HttpPostedFile postedFile = files[fileCount];
string fileName, fileExtension;

fileName = System.IO.Path.GetFileName(postedFile.FileName);
if (fileName != String.Empty)
{

fileExtension = System.IO.Path.GetExtension(fileName);

strMsg.Append("上传的文件类型：" + postedFile.ContentType.ToString() + "<br>");
strMsg.Append("客户端文件地址：" + postedFile.FileName + "<br>");
strMsg.Append("上传文件的文件名：" + fileName + "<br>");
strMsg.Append("上传文件的扩展名：" + fileExtension + "<br><hr color=red>");

postedFile.SaveAs(Server.MapPath("upedFile/") + fileName);
}
}
strStatus.Text = strMsg.ToString();

}
catch (System.Exception error)
{
strStatus.Text = error.Message;
}
}
protected void Upload_Click(object sender, EventArgs e)
{
upMorefile();
}

Code
<head id="Head1" runat="server">
<title></title>
<script language="JavaScript">
function addFileControl() {
var str = '<INPUT type="file" NAME="File">'
document.getElementById('FileCollection').insertAdjacentHTML("beforeEnd", str)
}
</script>
</HEAD>
