Csharp 通过将静态字段作为方法参数传递来更新静态字段

如果您允许调用者传递一个表达式树(Expression<Func<bool>>)，则可以这样做，然后您可以获得由表达式树引用的字段FieldInfo.

async void ToggleAbility(Expression<Func<bool>> field, bool value) {
    if (field.Body is MemberExpression memberExpression &&
        memberExpression.Member is FieldInfo fieldInfo) {
        
        // instead of field.Body, you can also use fieldInfo.Name for a simple name
        Logger.Write($@"{field.Body} = {fieldInfo.GetValue(null)}");

        // this sets the field's value
        fieldInfo.SetValue(null, value);

        // if you want to set it back asynchronously some time later...
        // await Task.Delay(...);
        // fieldInfo.SetValue(null, !value);
    } else {
        // the expression tree is not an access to a public static field
        // you could e.g. throw an exception 
    }
}

用途:

ToggleAbility(() => Hero1.awesomeAbility, true);

将字段设置为SetValue并不是很快.如果这对你来说是个问题，你可以 Select "野战二传手"Action<bool>

async void ToggleAbility(Action<bool> setter, bool value) {
    setter(value)
    await Task.Delay(...);
    setter(!vakue)
}

ToggleAbility(x => Hero1.awesomeAbility = x, true);

但是，您不能使用此方法访问字段名称或其当前值(以ToggleAbility为单位)，除非您还将它们作为附加参数传递:

ToggleAbility(
    x => Hero1.awesomeAbility = x, 
    true,
    nameof(Hero1.awesomeAbility),
    Hero1.awesomeAbility);

如果您的方法不需要是异步的，您还可以将该字段作为ref参数传递，如lidqy的答案所示.
