Compiler Warning (level 2) CS0652

Comparison to integral constant is useless; the constant is outside the range of type 'type'

The compiler detected a comparison between a constant and a variable where the constant is out of the range of the variable.

The following sample generates CS0652:

C#

// CS0652.cs  
// compile with: /W:2  
public class Class1  
{  
   private static byte i = 0;  
   public static void Main()  
   {  
      short j = 256;  
      if (i == 256)   // CS0652, 256 is out of range for byte  
         i = 0;  
   }  
}
