add a static property to a class in csharp

}

In the above example, we've added a static property MyStaticProperty to the class MyClass. This property can be accessed using the class name, rather than an instance of the class.

main.cs
MyClass.MyStaticProperty = 1;
int myValue = MyClass.MyStaticProperty;

Note that static properties are shared across all instances of the class and can be accessed even if no instances of the class have been created.
