推荐答案

这是可能的，但您必须将按钮属性的范围更改为 Public ，例如在窗体设计器中。然后你可以这样做：

It's possible, but you will have to change the scope of the button property to Public, e.g. in the Forms Designer. Then you can do this:

Form2.Button1.Enabled = False;

当然还有其他更复杂的方法......



好​​的，我会详细说明一下：

Of course there are also other more complicated ways ...

Ok, I will elaborate a bit more:

private void button1_Click(object sender, EventArgs e)
{
    var form2 = new Form2();

    // The 'Modifiers' property of button2 has been set to Public in the Forms designer.
    form2.button2.Enabled = false;
    form2.Show();
}

或者如果您需要在使用Form2时更改按钮：

Or if you need to change the button while Form2 is in use:

public partial class Form1 : Form
{
    Form2 form2 = new Form2();

    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        form2.Show();
    }

    private void buttonDisable_Click(object sender, EventArgs e)
    {
        // The 'Modifiers' property of button2 has been set to Public in the Forms designer.
        form2.button2.Enabled = false;
    }
}
