GUID in C#

I always forget useful stuff about GUID.

1. How to create GUID from string?

Guid newGuid = new Guid(Guid_As_String);

2. How to compare to GUID values?

Guid a;
Guid b;
if (a == b)
{
      // Do something
}

You can compare them with == operator because it is overloaded for Guid type (see here).

3. How to get new Guid?

Guid a = Guid.NewGuid();
