unity3d-有没有在c#中创建自定义关键字的方法？

我创建了这个简单的类，它的性能类似于if语句，但只有在其被触发时：

/// 

    /// Triggers the specified code in the execution block the first time that the paramaters return true
    /// 
    /// 
    /// 
    public When(Func validator, Action executor)
    {
        this.validator = validator;
        
        this.executor = executor;
        
        //Creates an object to start the coroutine
        GameObject dummyObj = new GameObject("_WhenClassDummyGameObjectForCoroutine");
        dummyObj.AddComponent().StartCoroutine(WhenCoRo());
        dummyObj.hideFlags = HideFlags.HideInHierarchy;
        
    }




    public IEnumerator WhenCoRo()
    {
        yield return null;
        while (true)
        {
            if (validator.Invoke())
            {
                executor.Invoke();
                yield break;
            }
            yield return null;
        }
    }

问题是，你需要以一种非常复杂的方式调用它：

When when = new When(() => b > a,
            () =>
            {
                Debug.Log("When Has Been Triggered");
            }
            );

我想做的是：

when (b > a)
{
    Debug.Log("When Has Been Triggered");
}

有人知道如何做到这一点吗？
