If the class implements two interfaces and these two interfaces contain members with the same signature, implementing this member in the class will result in both interfaces using this member as their implementation. For example:Interface iControl { Void paint (); } Interface isurface { Void paint (); } Class sampleclass: iControl, isurface { // Both isurface. Paint and

default. In Java, a method definition can carry a public modifier (even if this is not necessary), but in C #, explicitly specifying a public modifier for an interface method is invalid. For example, the following C # interface will generate a compilation error.

Look at the following example:Using System;Interface IControl {void Paint ();}Interface Itextbox:icontrol {void SetText (string text);}Interface Ilistbox:icontrol {void Setitems (string[] items);}Interface Icombobox:itextbox, IListBox {}Here, the interface IComboBox inherits ITextBox and IListBox. The class TextBox not only implements the interface ITextBox, but also implements the parent interface

interfaces cannot include variable members , only properties, events, methods, indexers (only two properties for the example above)3 The class implementing the interface must be implemented in strict accordance with the definition of the interface4 implementing an interface can be implemented implicitly and explicitlyFor example:Interface IControl//interface 1{void Paint ();}Interface ISurface//interface 2{void Paint ();}Note: Both of these interface
