Voorbeelden

In het volgende codevoorbeeld ziet u enkele van de methoden in Char.

using System;

public class CharStructureSample
{
    public static void Main()
    {
        char chA = 'A';
        char ch1 = '1';
        string str = "test string";

        Console.WriteLine(chA.CompareTo('B'));          //-----------  Output: "-1" (meaning 'A' is 1 less than 'B')
        Console.WriteLine(chA.Equals('A'));             //-----------  Output: "True"
        Console.WriteLine(Char.GetNumericValue(ch1));   //-----------  Output: "1"
        Console.WriteLine(Char.IsControl('\t'));        //-----------  Output: "True"
        Console.WriteLine(Char.IsDigit(ch1));           //-----------  Output: "True"
        Console.WriteLine(Char.IsLetter(','));          //-----------  Output: "False"
        Console.WriteLine(Char.IsLower('u'));           //-----------  Output: "True"
        Console.WriteLine(Char.IsNumber(ch1));          //-----------  Output: "True"
        Console.WriteLine(Char.IsPunctuation('.'));     //-----------  Output: "True"
        Console.WriteLine(Char.IsSeparator(str, 4));    //-----------  Output: "True"
        Console.WriteLine(Char.IsSymbol('+'));          //-----------  Output: "True"
        Console.WriteLine(Char.IsWhiteSpace(str, 4));   //-----------  Output: "True"
        Console.WriteLine(Char.Parse("S"));             //-----------  Output: "S"
        Console.WriteLine(Char.ToLower('M'));           //-----------  Output: "m"
        Console.WriteLine('x'.ToString());              //-----------  Output: "x"
    }
}

open System

Opmerkingen

Zie Aanvullende API-opmerkingen voor Char voor meer informatie over deze API.

Veiligheid thread

Alle leden van dit type zijn thread-veilig. Leden die de exemplaarstatus lijken te wijzigen, retourneren daadwerkelijk een nieuw exemplaar dat is geïnitialiseerd met de nieuwe waarde. Net als bij elk ander type moet lezen en schrijven naar een gedeelde variabele die een exemplaar van dit type bevat, worden beveiligd door een vergrendeling om de veiligheid van threads te garanderen.
