提示对话框中的Windows窗体 [英] Prompt Dialog in Windows Forms

问题描述

我使用 System.Windows.Forms的，但奇怪的是没有建立它们的能力。

I am using System.Windows.Forms but strangely enough don't have the ability to create them.

我怎么能得到这样一个JavaScript提示对话框，没有JavaScript的？

How can I get something like a javascript prompt dialog, without javascript?

的MessageBox是好的，但也没有办法为用户输入的输入。

MessageBox is nice, but there is no way for the user to enter an input.

推荐答案

您需要创建自己的提示对话框。也许你可以为此创建一个类。

You need to create your own Prompt dialog. You could perhaps create a class for this.

public static class Prompt
{
    public static string ShowDialog(string text, string caption)
    {
        Form prompt = new Form();
        prompt.Width = 500;
        prompt.Height = 150;
        prompt.FormBorderStyle = FormBorderStyle.FixedDialog;
        prompt.Text = caption;
        prompt.StartPosition = FormStartPosition.CenterScreen;
        Label textLabel = new Label() { Left = 50, Top=20, Text=text };
        TextBox textBox = new TextBox() { Left = 50, Top=50, Width=400 };
        Button confirmation = new Button() { Text = "Ok", Left=350, Width=100, Top=70, DialogResult = DialogResult.OK };
        confirmation.Click += (sender, e) => { prompt.Close(); };
        prompt.Controls.Add(textBox);
        prompt.Controls.Add(confirmation);
        prompt.Controls.Add(textLabel);
        prompt.AcceptButton = confirmation;

        return prompt.ShowDialog() == DialogResult.OK ? textBox.Text : "";
    }
}

和调用它：

string promptValue = Prompt.ShowDialog("Test", "123");
