Cleaner way to do a null check in C#? [duplicate]

Answer 1

The second question,

I really don't like the null check being done as (something == null). Instead, is there another nice way to do something like the something.IsNull() method?

could be solved using an extension method:

public static class Extensions
{
    public static bool IsNull(this T source) where T : class
    {
        return source == null;
    }
}
