How do you restrict the type which can be used in custom generic?..

Answer / kishore.a

To restrict a type in Generic just specify the constraint
immediately following the method header, prior to the curly
braces of the method block:

For EX: you can restrict a type parameter to implement
IComparable

public class ConsoleTreeControl
{
// Generic method Show<T>
public static void Show<T>(BinaryTree<T> tree, int indent)
where T : IComparable
{
//Your Code

}
}

So this cannot implement IComparable interface.
