如题求一个不用<input type="file"/>上传图片方法，我试过各种各样的方法，有的能上传但图片不显示，有的根本上传不了。请大家帮忙。
比如
string newFile = baseLocation + newname + filesUploaded + strType; //上传的文件路径和文件名
例:newFile = E:\\pic\\200907301212323.jpg
StreamWriter FSO;
//查看文件是否存在
if (File.Exists(newFile))
{
FSO = File.AppendText(newFile);
}
else
{
FSO = File.CreateText(newFile);
}
上面这个上传结果是有图片存在，但是图片没有任何内容，也就是一张空图片。
请大家帮帮忙给解决一下，或者个写个不用<input type="file"/>上传图片的例子。调试成功马上送分！
