Unable to change file name after File Upload using WebApi MultipartFormDataStreamProvider

Question

Im using WebApi to upload a file, but when I run

request.Content.ReadAsMultipartAsync(provider)

The file is uploaded but its file name is totally changed. I read something about that says that it is automatically made for security reasons. Anyway I want to store the file with the real file name. Any idea how to do it?

This simple override fix this issue

public class MyMultipartFormDataStreamProvider : MultipartFormDataStreamProvider
{
    public MyMultipartFormDataStreamProvider(string path) : base(path)
    { }

    public override string GetLocalFileName(System.Net.Http.Headers.HttpContentHeaders headers)
    {
        // override the filename which is stored by the provider (by default is bodypart_x)
        string originalFileName = headers.ContentDisposition.FileName.Trim('\"');

        return originalFileName;
    }
}
