以另一种形式更改按钮的颜色C＃

Question

我有2个窗体，名为Form1和Form2。

每个窗体都有3个按钮同名：Button1，Button2和Button3。

我想要的是当Form1中按钮的每种颜色都改变了，然后Form 2中按钮的每种颜色也改变了。例如，Form 1中的Button 1是绿色的，因此Form 1中的Button 1也是绿色的。

我该怎么做？这是我做了什么，它不工作

Form1中

Form2 form2 = new Form2();  

private void Klik_Click(object sender, EventArgs e) 
    { 
     counter++; 
     if(counter==1) 
     { 
     Button1.BackColor = Color.Red; 
     Button2.BackColor = Color.Red; 
     Button3.BackColor = Color.Red; 
     form2.Button1.BackColor = Color.Red; 
     form2.Button2.BackColor = Color.Red; 
     form2.Button3.BackColor = Color.Red; 
     } 
     if (counter > 1) 
     { 
     Button1.BackColor = Color.Green; 
     Button2.BackColor = Color.Green; 
     Button3.BackColor = Color.Green; 
     form2.Button1.BackColor = Color.Green; 
     form2.Button2.BackColor = Color.Green; 
     form2.Button3.BackColor = Color.Green; 
     counter = 0; 
     } 
    } 

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

Answer 1

你可以试试这个：

在窗口2创建一个属性调用ButtonColor public Color ButtonColor = new Color();

在form2_paint方法加入以下内容

Button1.BackColor = ButtonColor; 
Button2.BackColor = ButtonColor; 
Button3.BackColor = ButtonColor; 

将form1更改为

Form2 form2 = new Form2();  

private void Klik_Click(object sender, EventArgs e) 
    { 
     counter++; 
     if(counter==1) 
     { 
     Button1.BackColor = Color.Red; 
     Button2.BackColor = Color.Red; 
     Button3.BackColor = Color.Red; 
     form2.ButtonColor = Color.Red; 
     } 
     if (counter > 1) 
     { 
     Button1.BackColor = Color.Green; 
     Button2.BackColor = Color.Green; 
     Button3.BackColor = Color.Green; 
     form2.ButtonColor = Color.Green; 
     counter = 0; 
     } 
     form2.Show(); 
     form2.Refresh(); 
    }
