Caller information attributes (``++CallerFilePathAttribute++``, ``++CallerLineNumberAttribute++``, and ``++CallerMemberNameAttribute++``) provide a way to get information about the caller of a method through optional parameters. But they only work right if their values aren't provided explicitly. So if you define a method with caller info attributes in the middle of the parameter list, you put your callers in a bad position: they are forced to use named arguments if they want to use the method properly.


== Noncompliant Code Example

----
void TraceMessage([CallerMemberName] string memberName = "",
  [CallerFilePath] string filePath = "",
  [CallerLineNumber] int lineNumber = 0,
  string message = null)  // Noncompliant
{
  /* ... */
}
----


== Compliant Solution

----
void TraceMessage(string message = null,
  [CallerMemberName] string memberName = "",
  [CallerFilePath] string filePath = "",
  [CallerLineNumber] int lineNumber = 0) 
{
  /* ... */
}
