Wie ändere ich den Schaltflächentext für die Schaltflächen "Ja" und "Nein" im Dialogfeld "MessageBox.Show"?

Ich muss die Meldungsfeld-Steuertasten Yes in Continue und No in Close ändern. Wie ändere ich den Schaltflächentext?

Hier ist mein Code:

 DialogResult dlgResult = MessageBox.Show("Patterns have been logged successfully", "Logtool", MessageBoxButtons.YesNo, MessageBoxIcon.Information);

Fügen Sie einfach ein neues Formular hinzu und fügen Sie Schaltflächen und eine Beschriftung hinzu. Geben Sie den anzuzeigenden Wert und den Text der Schaltfläche usw. in den Konstruktor ein und rufen Sie ihn an einer beliebigen Stelle im Projekt auf.

In project -> Add Component -> Windows Form and select a form

Fügen Sie einige Beschriftungen und Schaltflächen hinzu.

Initialisieren Sie den Wert im Konstruktor und rufen Sie ihn von überall auf.

public class form1:System.Windows.Forms.Form
{
    public form1()
    {
    }

    public form1(string message,string buttonText1,string buttonText2)
    {
       lblMessage.Text = message;
       button1.Text = buttonText1;
       button2.Text = buttonText2;
    }
}

// Write code for button1 and button2 's click event in order to call 
// from any where in your current project.

// Calling

Form1 frm = new Form1("message to show", "buttontext1", "buttontext2");
frm.ShowDialog();

Ich hätte nicht gedacht, dass es so einfach sein würde! Gehen Sie zu diesem Link: https://www.codeproject.com/Articles/18399/Localizing-System-MessageBox

Laden Sie die Quelle herunter. Nehmen Sie die MessageBoxManager.cs-Datei und fügen Sie sie Ihrem Projekt hinzu. Registrieren Sie es jetzt einfach einmal in Ihrem Code (zum Beispiel in der Main () -Methode in Ihrer Program.cs-Datei) und es funktioniert jedes Mal, wenn Sie MessageBox.Show () aufrufen:

    MessageBoxManager.OK = "Alright";
    MessageBoxManager.Yes = "Yep!";
    MessageBoxManager.No = "Nope";
    MessageBoxManager.Register();

Siehe diese Antwort für den Quellcode hier für MessageBoxManager.cs .

Dies ist möglicherweise nicht die schönste, aber wenn Sie den MessageBoxManager nicht verwenden möchten (was fantastisch ist):

 public static DialogResult DialogBox(string title, string promptText, ref string value, string button1 = "OK", string button2 = "Cancel", string button3 = null)
    {
        Form form = new Form();
        Label label = new Label();
        TextBox textBox = new TextBox();
        Button button_1 = new Button();
        Button button_2 = new Button();
        Button button_3 = new Button();

        int buttonStartPos = 228; //Standard two button position


        if (button3 != null)
            buttonStartPos = 228 - 81;
        else
        {
            button_3.Visible = false;
            button_3.Enabled = false;
        }


        form.Text = title;

        // Label
        label.Text = promptText;
        label.SetBounds(9, 20, 372, 13);
        label.Font = new Font("Microsoft Tai Le", 10, FontStyle.Regular);

        // TextBox
        if (value == null)
        {
        }
        else
        {
            textBox.Text = value;
            textBox.SetBounds(12, 36, 372, 20);
            textBox.Anchor = textBox.Anchor | AnchorStyles.Right;
        }

        button_1.Text = button1;
        button_2.Text = button2;
        button_3.Text = button3 ?? string.Empty;
        button_1.DialogResult = DialogResult.OK;
        button_2.DialogResult = DialogResult.Cancel;
        button_3.DialogResult = DialogResult.Yes;


        button_1.SetBounds(buttonStartPos, 72, 75, 23);
        button_2.SetBounds(buttonStartPos + 81, 72, 75, 23);
        button_3.SetBounds(buttonStartPos + (2 * 81), 72, 75, 23);

        label.AutoSize = true;
        button_1.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;
        button_2.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;
        button_3.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;

        form.ClientSize = new Size(396, 107);
        form.Controls.AddRange(new Control[] { label, button_1, button_2 });
        if (button3 != null)
            form.Controls.Add(button_3);
        if (value != null)
            form.Controls.Add(textBox);

        form.ClientSize = new Size(Math.Max(300, label.Right + 10), form.ClientSize.Height);
        form.FormBorderStyle = FormBorderStyle.FixedDialog;
        form.StartPosition = FormStartPosition.CenterScreen;
        form.MinimizeBox = false;
        form.MaximizeBox = false;
        form.AcceptButton = button_1;
        form.CancelButton = button_2;

        DialogResult dialogResult = form.ShowDialog();
        value = textBox.Text;
        return dialogResult;
    }
