# V6022. Parameter is not used inside method's body.

The analyzer detected a suspicious situation when one parameter of a method is never used while another parameter is used several times. It may be a sign of an error.

Consider the following example:

    private static bool CardHasLock(int width, int height)
    {
      const double xScale = 0.051;
      const double yScale = 0.0278;

      int lockWidth  = (int)Math.Round(height * xScale);
      int lockHeight = (int)Math.Round(height * yScale);
      ....
    }

The 'width' parameter is never used in the method body while the 'height' parameter is used twice, including the initialization of the 'lockWidth' variable. This code is very likely to contain an error and the 'lockWidth' variable should be actually initialized in the following way:

    int lockWidth = (int)Math.Round(width * xScale);

This diagnostic is classified as:

CERT-MSC56-J
