    NotBeUpperCased Method
    In This Topic

    Syntax
    public AndConstraint<TAssertions> NotBeUpperCased( 
   string because,
   params object[] becauseArgs
)

    Parameters

    because
    A formatted phrase as is supported by System.String.Format(System.String,System.Object[]) explaining why the assertion is needed. If the phrase does not start with the word because, it is prepended automatically.

    because
    Remarks
    Numbers, special characters, and many Asian characters don't have casing, so NotBeUpperCased will ignore these and will fail only if the string contains cased characters and they are all upper-case.
