新建了一个产品帮助手册模型，怎么获取附件的大小及扩展名。因为需要在前台显示附件大小及扩展名。

<script runat="server" language="c#">
private string filesize(string files) //获取文件大小
{
strin Rn = "";
if (!string.IsNullOrEmpty(files))
{
if (System.IO.File.Exists(Server.MapPath(files)))
{
System.IO.FileInfo FI = new System.IO.FileInfo(Server.MapPath(files));
Rn= FI.Length.ToString() ;
}
}
return Rn;
}
private string fileext(string files) //获取文件扩展名
{
strin Rn = "";
if (!string.IsNullOrEmpty(files))
{
if (System.IO.File.Exists(Server.MapPath(files)))
{
System.IO.FileInfo FI = new System.IO.FileInfo(Server.MapPath(files));
Rn= FI.Extension;
}
}
return Rn;
}
</script>

把这个方法放在模型顶部，模型中直接调用.
