c# - if 语句可以与使用模式匹配的变量赋值相结合吗？

Question

我正在谈论的代码示例:

if (sender is Panel p)
{
    if (p.Enabled == false)
    {
        AMButton.Checked = false;
        PMButton.Checked = false;
        currentSelectedTime = null;
    }
}

一旦变量 p 在第一个 if 语句中被强制转换从而组合两个语句，是否有可能对变量 p “做更多的事情”？

Answer 1

Something such as if(sender is Panel p.Enabled). Combining the two if statements into one line like that. Does that make sense?

if(sender is Panel p && p.Enabled)

或者变得丑陋

if(sender is Panel p && (p.Enabled = somethingElse) == ((someInt = anotherInt) == 5))
