Question

在编写C＃时，我是新手，所以请不要对我太苛刻。我以前用ActionScript编码，并注意到它非常相似。

无论如何，我需要基本上构建一个简单的应用程序，其中2个字符互相给予“钱”......或整数。字符名称应该是动态的，按钮应该起到名称的作用。

请帮忙！这就是我到目前为止所做的：

namespace Lab_2
{
    public partial class Form1 : Form
    {
        Guy firstName;
        Guy secondName;
        int bank = 100;

        public Form1()
        {
            InitializeComponent();

            firstName = new Guy() { Cash = 100, Name = "Joe" };
            secondName = new Guy() { Cash = 50, Name = "Bob" };

            firstName = textBox1.Text;
            secondName = textBox2.Text;

            UpdateForm();
        }

        public void UpdateForm()
        {
            name1CashLabel.Text = firstName.Name + " has $" + firstName.Cash;
            name2CashLabel.Text = secondName.Name + " has $" + secondName.Cash;
            bankCashLabel.Text = "The bank has $" + bank;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            button1.Text = "Give $10 to " + firstName.Name;

            if (bank >= 10)
            {
                bank -= firstName.ReceiveCash(10);
                UpdateForm();
            }
            else
            {
                MessageBox.Show("The bank is out of money.");
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            bank += secondName.GiveCash(5);
            UpdateForm();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            secondName.ReceiveCash(firstName.GiveCash(10));
            UpdateForm();
        }

        private void button4_Click(object sender, EventArgs e)
        {
            firstName.ReceiveCash(secondName.GiveCash(5));
            UpdateForm();
        }

        private void name1_Click(object sender, EventArgs e)
        {
            firstName.Name = textBox1.Text;
        }
    }
}

Answer 1

关键位似乎是name1_Click方法，它将firstName对象的Name更新为文本框的内容。完成后，您需要刷新按钮的标题。

我会创建一个新方法：

public void RefreshButtonCaptions()
{
    button1.Text = "Give $10 to " + firstName.Name;
    button2.Text = "Give $10 to " + secondName.Name;
}

然后从name1_Click：

调用它

private void name1_Click(object sender, EventArgs e)
{
    firstName.Name = textBox1.Text;
    RefreshButtonCaptions()
}

Answer 2

如果您想在按钮上显示新名称，可以像下面这样简单地更新它们：

private void name1_Click(object sender, EventArgs e) 
{ 
    firstName.Name = textBox1.Text; 
    button1.Text = "Give $10 to " + firstName.Name;
}

对于name2_click（如果有的话）可能相同：

private void name2_Click(object sender, EventArgs e) 
{ 
    secondName.Name = textBox2.Text; 
    button2.Text = "Give $10 to " + secondName.Name;
}

在C＃中，如何使按钮的文本动态化？
