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.

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.
