Why does C # not accept logical operators in the form of words ("and", "or", "not", etc.) with current operators?

Question

Mine if stetement:

if (!string.IsNullOrEmpty(Person.Name))
        // some code

I think that "!" the operator is less readable when writing imperative code,

Do you agree with me, is the following code more readable?

if (not string.IsNullOrEmpty(Person.Name))
            // some code

I'm not talking about replacing current operators, but where is the problem if the language accepts them?

Answer 1

There are several good reasons:

• , . , AND , (& vs &). VB (ish) AND AndAlso. . , .

• . , , , - , , , .

• , C, Java, Objective-C ++. 40 (?) - . , .

• "", "" "" - ! && & .

Answer 4

. . , AND (& &), - false, , , OR (||), - true, .

//...
// Position is a class
private bool checkMate(ref int numberOfPlies, ref ChessPosition position, int maxNumberOfPlies, List<Move> moves)
{
    if (numberOfPlies > maxNumberOfPlies)
        return false;
    position.makeMove(moves[numberOfPlies]);
    if (!(position.getSuccessOfLastMove())))
        return false;
    numberOfPlies++;
    return ((
            ((isCheckMate()) ||
            ((checkMate(ref numberOfPlies, ref position, maxNumberOfPlies, moves)))
           ));
}
