下面是一个例子：
<%@ Page Language="C#" %>
<%@ Import Namespace="System.IO" %>
<script type="text/c#" runat="server">
protected void BtnUpload_Click(object sender, EventArgs e)
{
if (Request.Files != null)
{
foreach (string file in Request.Files)
{
var uploadedFile = Request.Files[file];
if (uploadedFile.ContentLength > 0)
{
var appData = Server.MapPath("~/app_data");
var fileName = Path.GetFileName(uploadedFile.FileName);
uploadedFile.SaveAs(Path.Combine(appData, fileName));
}
}
}
}
</script>
<!DOCTYPE html>
