asp.net网页中不用服务器控件可以上传文件吗？
在asp.net   的网页中，采用以下服务器控件 <input   id= "myFile "   type= "file "   name= "myFile "   runat= "server "> 可轻易实现上传文件，可如果仅使用html静态控件如 <input   name= "myFile "   type= "file "   /> ，也能实现上传文件吗？？？  
哪位大侠帮小弟解决一下。最好能给出代码。

private bool SavePicture()
{
/// '遍历File表单元素
HttpFileCollection files = HttpContext.Current.Request.Files;
try
{
for (int iFile = 0; iFile < files.Count; iFile++)
{
/// '检查文件扩展名字
HttpPostedFile postedFile = files[iFile];
string fileName, fileExtension;
fileName = System.IO.Path.GetFileName(postedFile.FileName);
fileExtension = System.IO.Path.GetExtension(fileName);

#region 更改名字
string writename = DateTime.Now.ToString( "yyyyMMddHHmmss ") + fileExtension;

if (File.Value != " ")
{
postedFile.SaveAs(System.Web.HttpContext.Current.Request.MapPath( "../MemberImage/ ") + writename);
memberimage = "MemberImage/ " + writename;
}
else
{
memberimage = hidImage.Value;
}
#endregion
}
return true;
}
catch (System.Exception Ex)
{
return false;
}
}
