'<method1>' cannot override '<method2>' because they differ by the default values of optional parameters

  • Article

You have attempted to override a method with another method that differs from the first in the default values of its optional parameters, meaning that their signatures differ. A type may override an inherited overridable method by declaring a method with the same name and signature, and marking the declaration with the Overrides modifier.

Error ID: BC30307

To correct this error

  • Make sure the two methods have the same signature.
