What is the fastest way of getting a file length in .net?

Question

What is the fastest way of getting a file length in .net?

Note: I am accessing files via a network share.

So far I have

• 1.5ms FileInfo.Length
• .5ms FileStream().Length

Answer 1

Derived from Adi_aks answer

public static long GetFileLength(string path)
{
    using (var fileStream = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read))
    {
        return fileStream.Length;
    }
}
