hi i have the following struct

      public struct Camera
      {
            public Coordinate Coordinate;
            public int Pitch;
            public int Altitude;
            public int Direction;
            public int Distance;
      }

what i want to is when the value is set for Direction i want to only allow 1 to 360 positive range to be allowed, how would i do this within my sruct so that i do not have to include any validation code on all the pages which use the struct.

I hope this makes sence

    Hi,

    Might want to rewrite it using Direction as a property:

    struct Camera
    {
          private int direction;

          public int Direction
          {
                set
                {
                      if(value < 0 || value > 360)
                            throw new ArgumentException("Value must be between 0 and 360");
                      this.direction = value;
                }
          }
    }

    HTH,

    I'm not quite sure what you mean. You can just use this code for the struct and use it like you used the struct before. Is that what you want to know?

    Hope the lorry driver is ok ;)
