UserCancellationException Constructor (String, Exception)
Initializes an instance of the UserCancellationException class with the specified error message and a reference to the inner exception that is the cause of this exception.
Assembly: System.IdentityModel.Selectors (in System.IdentityModel.Selectors.dll)
An exception that is thrown as a direct result of a previous exception should include a reference to the previous exception in the InnerException property. The InnerException property returns the same value that is passed into the constructor, or a null reference (Nothing in Visual Basic) if the InnerException property does not supply the inner exception value to the constructor.
