   9 // ReflectionTypeLoadException is thrown when multiple TypeLoadExceptions may occur.
  10 //
  11 // <OWNER>Microsoft</OWNER>
  12 //  Specifically, when you call Module.GetTypes() this causes multiple class loads to occur.
  13 //  If there are failures, we continue to load classes and build an array of the successfully
  14 //  loaded classes.  We also build an array of the errors that occur.  Then we throw this exception
  15 //  which exposes both the array of classes and the array of TypeLoadExceptions.
