  var fileName = Path.GetFileName（file.FileName）; 
 

或在其他情况下您可以做

  var name = file.FileName.Split（'，'）[1] .ToString（）; 
 

I'm pretty new to MVC and I'm trying to get just the file name of the newly selected file.

The html code looks like this:

<form action="Url.Action("UploadImage","Util")" method="POST" enctype="multipart/form-data" encoding="multipart/form-data">
<input name="file" type="file" accept="image/*" title="Browse..." />
</form>

The .cs function looks like this:

[HttpPost]
public String UploadImage(HttpPostedFileBase file)
{
     if(file == null) throw new ArgumentNullException("File");
     return file.FileName;
}

What I'm getting back is data:image/png;base64,add_32x32.png and all I want is add_32x32.png

How can I get this result?

you can try this just to extract the file name

 var fileName = Path.GetFileName(file.FileName);

or in other case you can do

var name = file.FileName.Split(',')[1].ToString();
