如何从C＃检索/获取CAB FileUnique版本号？

Question

I have an application in windows mobile 6.after deploying the application,it will create a CAB file. I Want to Upload this CAB file To Server using File Upload Control From Asp.Net Web Form..

While Uploading I want to check the CAB file is already Uploaded Before by checking its version number[Unique Generated by .NET while Deploying] rather than Just its name.

How to get this unique version from C# ???

Please help me on this.....

Thanks in Advance

Why not just use an MD5 hash of the file itself? That's going to give you a pretty good uniqueness.

public string GetFileHash(string fileName)
{
    using (var stream = File.Open(fileName, FileMode.Open))
    {
        var md5 = new MD5CryptoServiceProvider();
        var hash = md5.ComputeHash(stream);

        var sb = new StringBuilder();
        for (int i = 0; i < hash.Length; i++)
        {
            sb.Append(hash[i].ToString("x2"));
        }
        return sb.ToString();
    }
}
