Syntax Explanation: public class TestClass : MarshalByRefObject{}

Question

I was hoping someone can assist with a thorough explanation on the syntax below in row 3. I was trying to search for it but couldn't get something that explains it for me nicely.

I am looking to understand not just this specific syntax but the generalized theory behind it, so that if I see something similar in the future I will be able to tell what is what.

1 using System;
2
3 public class TestClass : MarshalByRefObject{}

The `:` means "inherits from". So `TestClass` inherits from `MarshalByRefObject`. Is that what you're asking? This question is better answered by an introductory book on the C# language. — Cody Gray, May 10 '14 at 11:39

It is just an empty class inheriting from MarshalByRefObject — BlackBear, May 10 '14 at 11:41

@Code Gary, thanks that was what I was looking for. I wasn't sure what the ":" means. Now I can go read up on it. — CodeMantis, May 10 '14 at 11:48

As @BlackBear said and empty class inheriting "MarshalByRefObject" this formatting might give a clearer look:

using System;
public class TestClass : MarshalByRefObject
{
     //No implementation
}

Am I correct to state then, when you use inheritance you effectively merge two classes into one, allowing you to use both the properties of TestClass and MarshalByRefObject in TestClass? I understand there are subtleties involved that I might not fully understand yet, but from a high level view. http://msdn.microsoft.com/en-us/library/ms173149(VS.80).aspx – CodeMantis May 10 '14 at 11:57
In the most simplistic sense, yes. a child class will receive all the public and protected members of the parent. from a semantic perspective its a way of defining a more specialized version of the parent class, like a School is a more specialized version of a "LearningInstitution" or a Car is a Vehicle. – Tamim Al Manaseer May 10 '14 at 14:45
