Unity之Specified cast is not valid.报错

Unity之Specified cast is not valid.报错

foreach (Gameobject child in Instance.slotGrid.gameObject.transform)
{
    Destroy(child.gameObject);
}

我调试了一会儿，发现百思不得其解，就百度了下这个错误，然后大概猜出这应该是个类型导致的错误。

foreach (Transform child in Instance.slotGrid.gameObject.transform)
{
    Destroy(child.gameObject.gameobject);
}

再在Unity中运行，没有报错了！

总结：Unity 报错“Specified cast is not valid”，是类型错误。
