Declare a member function as static. Such functions can access only static variables. The static functions exist even before the object is created.
A static class cannot be instantiated and can only contain static members.
Static methods is set using static keyword −
public static int getNum() {
return num;
}下面的示例演示了静态和非静态方法的使用 −
示例
using System;
namespace StaticVarApplication {
class StaticVar {
public static int num;
public void count() {
num++;
}
public static int getNum() {
return num;
}
}
class StaticTester {
static void Main(string[] args) {
StaticVar s = new StaticVar();
s.count();
s.count();
s.count();
s.count();
s.count();
s.count();
Console
