How to change the button text for 'Yes' and 'No' buttons in the MessageBox.Show dialog?

I need to change the message box control buttons Yes to Continue and No to Close. How do I change the button text?

Here is my code:

 DialogResult dlgResult = MessageBox.Show("Patterns have been logged successfully", "Logtool", MessageBoxButtons.YesNo,开发者_如何转开发 MessageBoxIcon.Information);

I didn't think it would be that simple! go to this link: https://www.codeproject.com/Articles/18399/Localizing-System-MessageBox

Download the source. Take the MessageBoxManager.cs file, add it to your project. Now just register it once in your code (for example in the Main() method inside your Program.cs file) and it will work every time you call MessageBox.Show():

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

See this answer for the source code here for MessageBoxManager.cs.

Just add a new form and add buttons and a label. Give the value to be shown and the text of the button, etc. in its constructor, and call it from anywhere you want in the project.

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

Add some label and buttons.

Initialize the value in constructor and call it from anywhere.

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();

This may not be the prettiest, but if you don't want to use the MessageBoxManager, (which is awesome):

 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;
    }
