用ASP上传文件。获得名称但没有文件流，我做错了什么?

I have this form in my view:

我的观点是这样的:

<!-- Bug (extra 'i') right here-----------v  -->
<!-- was: <form method="post" enctype="mulitipart/form-data" action="/Task/SaveFile"> -->
<form method="post" enctype="multipart/form-data" action="/Task/SaveFile">
<input type="file" id="FileBlob" name="FileBlob"/>
<input type="submit"  value="Save"/>
<input type="button" value="Cancel" onclick="window.location.href='/go.html?url=/'" />
</form>
