Maybe someone would explain the difference between a shallow copy and a deep copy in C #: A shallow copy is a copy of an address to a reference type and a direct copy of a value type. It cannot be said that it is completely wrong, but at least not

Issue 1: Virtual methodsFirst, look at the following code.namespacecsharptest{classA Public void Fun() {Console.WriteLine ("This is the parent class method"); } }classb:a { Public void Fun() {Console.WriteLine ("This is a subclass method"); }

First we move the item and force it to a>b.And then we can draw an image like this.We found that the absolute value of x, Y is incremented at the intersection of the segment L and the x-axis, so we don't consider the minimum point at the bottom.Then
