C # contains generic classes, generic methods, generic interfaces, and generic delegation. The first three types are introduced below. 1. generic classes and generic methods: 1 /// 2 /// generic class and generic method 3 /// 4 /// 5 class

When commissioned in the era of C #1, it is estimated that no one can expect such a huge impact on the C # language. C #1 create a delegated instance. The delegate type and operation must be specified. Declare to delegate Public Delegate bool
