如何获取 NewQuestion 按钮中的检查变量以更改表单检查变量

Question

如何在 NewQuestion 按钮中获取检查变量以更改表单检查变量。

我正在考虑在此按钮更改后在另一个按钮中使用检查值。

public Form1()
{
    InitializeComponent();
}

int check = 0;

private void btnNewQuestion_Click(object sender, EventArgs e)
{
    int check = 1;
}

我不确定您的主要目标，我认为可能有更好的方法来完成您想要做的事情。也就是说，您可以根据需要在同一个表单中简单地引用您的表单级别变量。

public Form1()
{        
    InitializeComponent();
}

int check = 0; // form level variable

private void btnNewQuestion_Click(object sender, EventArgs e)
{
    // int check = 1; // don't do this; this will create another 'check' variable that is only scoped within the button event
    check = 1; // to set the form level check value, just reference the form level variable like so
}

private void btnSomeOtherButton_Click(object sender, EventArgs e)
{
    // then reference it in the other button where you need it
    if(check == 1)
    {
        // do some stuff
    }
}
