在C#Windows窗体应用程序中，每次单击时按钮文本都会发生更改 在按钮上，通过下面的方法“m1”，按钮的首次点击文本应为“01”

通过下面的方法“m2”，按钮的第二次点击文本应为“02”

第三次点击“01”

再次点击“02”

等等

您可以尝试以下方法：

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

这可能对你有帮助

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;
}

如果你想调用这个函数

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

像这样的东西应该适合你

   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";

    }

方法m1和m2似乎是私有的，但标记为公共的。这可以通过计算点击次数来实现。如果这是asp.net，则单击次数应存储在数据库或会话中。如果这是WPF，那么点击次数可以存储在一个静态变量中。代码应该是这样的

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

这是asp.net吗？如果是，请在问题和标签中添加更多详细信息。请在回答中添加解释，以帮助未来用户。

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

    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";}

}

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


        if (b)
        {
            m1();

        }
        else 
        {
            m2();

        }
        b = !b;

    }
