I want to remove all null properties in a generic object. It doesn't have to be recursive, one level deep is also fine.

The function ...

Meaning, a call like: MyMethod(10, "eleven"); For method: void MyMethod(int Test, str Test2) {} Would resolve in an array like: {{"Test" => 10}, {"Test2", "eleven"}} Would be even better if I cou...

I have an instance of System.Type, for which "IsArray" returns true. How can I determine the "nested type" of the array type? i.e. Type GetArrayType(Type t) { if(t.IsArray) { // What to put here? } throw new Exception("Type is not an array"); } Assert.That(GetArrayType(typeof(string[])), Iz.EqualTo(typeof(str...
