Question

我有这个创建单选按钮的代码，当我单击按钮时，当单击按钮检查单选按钮时，有人可以向我显示单独选择每个按钮的代码吗？如何使每个单选按钮的文本不同？

private void createButtons()
        {
            flowLayoutPanel1.Controls.Clear();
            for(int i = 0;i <10;i++)
            {
                RadioButton b = new RadioButton();
                b.Name = i.ToString();
                b.Text = "radiobutton" + i.ToString();
                b.AutoSize = true;
                flowLayoutPanel1.Controls.Add(b);

            }
        }

每个按钮的文字已经不同了。当您在for循环中移动时，您将在末尾附加一个数字。听起来你只需要在动态创建的单选按钮的CheckedChanged事件上添加一个处理程序，这样你就可以根据点击的那个做一些事情。

您只需要将此行添加到for循环中的构建步骤：

b.CheckedChanged += RadioButtonClicked;

然后定义适当的方法：

private void RadioButtonClicked(object sender, EventArgs e)
{
    var radioButton = (RadioButton)sender;

    // Only run on checked items (per your comments).
    // This condition will cause the uncheck action/event to exit here.
    if (!radioButton.Checked)
    {
        return;
    }

    // Alternately, you could use a switch statement.
    if (radioButton.Name == "1")
    {
        // do something...
    }
    else if (radioButton.Name == "2")
    {
        // do something else...
    }
    // ...
}

根据您的评论，我建议您使用常规Button代替RadioButton。

以下是为每个消息显示唯一消息的实现：

private void createButtons()
{
    flowLayoutPanel1.Controls.Clear();
    for (int i = 1; i <= 65; i++)
    {
        Button b = new Button();
        b.Name = i.ToString();
        b.Text = "Translate" + i.ToString();
        b.Click += b_Click;
        flowLayoutPanel1.Controls.Add(b);
    }
}

void b_Click(object sender, EventArgs e)
{
    Button b = sender as Button;

    string TextBoxValue = string.Empty;

    switch (b.Name)
    {
        case "1":
            TextBoxValue = "Get the Translation for item # 1 here";
            break;
        case "2":
            TextBoxValue = "Get the Translation for item # 2 here";
            break;
        // ETC....  3,4,5
        default:
            TextBoxValue = "Button #(" + b.Name + ") is not handled";
            break;
    }

    MessageBox.Show(this, TextBoxValue, "Translation");
}

如何为单个单选按钮制作和if else语句？
