C＃Windows Form应用程序中每次单击时按钮文本的更改

Question

• 通过以下方法“ m1”，按钮上的首次单击文本应为“ 01”

• 通过以下方法“ m2”，按钮的第二次单击按钮上的文本应为“ 02”

• 然后第三次点击“ 01”

• 再次点击“ 02”
• 依此类推

private void button1_Click(object sender, EventArgs e)
{
}

public void m1()
{
    button1.Text = "01";
}

public void m2()
{
    button1.Text = "02";
}

Answer 1

这可能对您有帮助

public bool dirtyBool = true; //Initialize it on contructor
private void button1_Click(object sender, EventArgs e)
{
    if(dirtyBool)
    {
        button1.Text = "01";
    }
    else
    {
        button1.Text = "02";
    }
    dirtyBool = !dirtyBool;
}

如果要调用该函数，则

private void button1_Click(object sender, EventArgs e)
{
    if(dirtyBool)
    {
        m1()
    }
    else
    {
        m2()
    }
    dirtyBool = !dirtyBool;
}

Answer 2

public Boolean b = true;
    private void button1_Click(object sender, EventArgs e)
    {


        if (b)
        {
            m1();

        }
        else 
        {
            m2();

        }
        b = !b;

    }

Answer 3

您可以尝试这样的事情：

private void button1_Click(object sender, EventArgs e)
{
    button1.Text == "01" ? m2() : m1();
}

Answer 4

这样的事情应该为您工作。

   private bool isEvenClick;
   private void button1_Click(object sender, EventArgs e)
    {
        if (!isEvenClick)
        {
            m1();
            isEvenClick = true;
        }
        else
        {
            m2();
            isEvenClick = false;
        }
    }

    public void m1()
    {
        button1.Text = "01";

    }

    public void m2()
    {
        button1.Text = "02";

    }

Answer 5

方法m1和m2似乎是私有的，但已标记为公开。 这可以通过计算点击次数来实现。 如果是asp.net，则应将点击次数存储在数据库或会话中。 如果这是WPF，则点击次数可以存储在静态变量中。 该代码应如下所示。

private void button1_Click(object sender, EventArgs e)
{
  int numOfClicks = GetClickCount();
  button1.Text = numOfClicks % 2 == 0 ? "02" : "01";
}

Answer 6

    private void button1_Click(object sender, EventArgs e)
    {            
        count++;   //increment the variable on every button click that is declared globally 
        if(count%2==0)//checking the condition
            m2();//calling the method if the condition is true
        else  m1(); //else calling another method

    }
    public void m1()//method1
    { button1.Text = "01";}      
    public void m2()//method2
    {button1.Text = "02";}

}
