How to check if an object is not of a particular type?

Question

I want to check if an object is not of a particular type. I know how to check if something is of a particular type:

if (t is TypeA)
{
   ...
}
         


        

Answer 1

Extensions methods to the rescue!!

public static class ObjectExtensions
{
    public static bool Isnt(this object source, Type targetType)
    {
        return source.GetType() != targetType;
    }
}

Usage

if (t.Isnt(typeof(TypeA)))
{
   ...
}
