Adding and Releasing References in C#

C# automatically adds object references when you assign the object to another variable, as shown in the following code:

referenceObj = otherReferenceObj;

C# also automatically releases object references when a variable or list that contains a reference to an object goes out of scope. Local variable scope ends when the function returns. You can initiate the release of a reference to an object by setting the variable to the value null, as shown in the following code:

referenceObj = null;
