c# - How to get the image file name in an http post request

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();
