Patch for FileStream.cs (diffed against

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US)
AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.70 Safari/533.4

Tested against, 2.6.4.

FileStream.Name property is "Unknown" When using the ctor overload :
public FileStream (string path, FileMode mode, FileAccess access, FileShare
share, int bufferSize, bool useAsync)

This is because of incorrect constructor chain. Patch (for branch) is

Test case :

   static void Main(string[] args)
            string path = "test.txt";
            File.WriteAllText(path, "***************************");
            FileStream fs = new FileStream(path, FileMode.OpenOrCreate,
FileAccess.ReadWrite, FileShare.None, 1024 * 8, true);
            if (fs.Name.EndsWith("test.txt"))            
                Console.WriteLine("ALL OK !");
                Console.WriteLine("Something Bad Happened, name was '{0}' !",

Reproducible: Always

Steps to Reproduce:
1. Run test program

Actual Results:  
program outputs "Something Bad Happened, name was '[Unknown]' !"

Expected Results:  
program outputs "All OK !"
