Why isn't Guid.ToString(“n”) the same as a hex string generated from a byte array of the same guid?

Question

Consider the following unit test:

    [TestMethod]
    public void TestByteToString()
    {
        var guid = new Guid(\"61772f3ae5de5f4a8577eb1003c5c054\");
           


        

Answer 1

A GUID is structured as follows:

int a
short b
short c
byte[8] d

So for the part represented by a your code gets the bytes reversed. All other parts are transformed correctly.
