MessageBox.Showダイアログで「はい」および「いいえ」ボタンのボタンテキストを変更する方法

メッセージボックスコントロールボタンYesContinueに、NoCloseに変更する必要があります。ボタンのテキストを変更するにはどうすればよいですか?

ここに私のコードがあります:

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

新しいフォームを追加し、ボタンとラベルを追加するだけです。表示する値とボタンのテキストなどをコンストラクターで指定し、プロジェクト内の任意の場所から呼び出します。

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

いくつかのラベルとボタンを追加します。

コンストラクターで値を初期化し、どこからでも呼び出します。

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();

そんなに簡単だとは思いませんでした!このリンクにアクセスしてください: https://www.codeproject.com/Articles/18399/Localizing-System-MessageBox

ソースをダウンロードします。 MessageBoxManager.csファイルを取得して、プロジェクトに追加します。コードに一度登録するだけで(たとえば、Program.csファイル内のMain()メソッドで)、MessageBox.Show()を呼び出すたびに機能します。

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

MessageBoxManager.cs のソースコードについては、 この回答 を参照してください。

これは最もきれいではないかもしれませんが、MessageBoxManagerを使用したくない場合(これは素晴らしいです):

 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;
    }
