Windows 窗体中的提示对话框

问题描述

我正在使用 System.Windows.Forms 但奇怪的是没有能力创建它们.

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

如何在没有 javascript 的情况下获得类似 javascript 提示对话框的内容?

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

MessageBox 不错，但用户无法输入.

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

我希望用户输入任何可能的文本输入.

I want the user to enter any text input possible.

推荐答案

您需要创建自己的提示对话框.您也许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()
        {
            Width = 500,
            Height = 150,
            FormBorderStyle = FormBorderStyle.FixedDialog,
            Text = caption,
            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 : "";
    }
}

并称它为:

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

更新:

添加了默认按钮(输入键)和基于评论的初始焦点和另一个问题.

Added default button (enter key) and initial focus based on comments and another question.
