o.GetType().IsValueType

Use IsValueType like this:

if (yourObject.GetType().IsValueType) {
    // it's a value type
} else {
    // it's a reference type
}

They already answered, but don't forget that, if an object is an instance of a class, then it is a reference type, and if an object is an "instance" of a struct, then it is a value type. But there is an exception. String is a reference type but behaves like value type, because of a immutability.
