Use readonly : Readonly : Class C# Examples

Use readonly

You can create a read-only field in a class by declaring it as readonly.
A readonly field can be initialized, but not changed after that.




    
using  System;  
  
class  MainClass  {  
    public  static  readonly  int  SIZE  =  10;  
    
    public  static  void  Main()  {  
        int[]  nums  =  new  int[MainClass.SIZE];  
  
        //  MainClass.SIZE  =  100;  //  Error!!!  can't  change  
    }  
}
