Is Guid considered a value type or reference type?

Guids are created using the new keyword which makes me think it's a reference type.

Is this correct?

Guid uid = new Guid();

Are Guids stored on the heap?

Solution

  • You can see the definition of a Guid yourself:

    public struct Guid ...

    Or you can test it like this:

    bool guidIsValueType = typeof(Guid).IsValueType;

    Quote: "GUID's are created using the new keyword which makes me think it's a reference type."

    Structs can have constructors too, for example new DateTime(2012, 12, 23).
