我已经创建了一个自定义ToolStrip控件和ToolStripControl控件，以便我可以完全自定义它们的所有部分主要是悬停事件，但是我在Designer中遇到了一个问题，它会抛出此错误：
'child'不是此父级的子控件
这是我添加控件时的代码
CheckType我上面引用的private bool CheckType(Type check, Type checkType)
{
if (check == checkType)
{
return true;
}
else
{
if (check.BaseType != null)
{
return CheckType(check.BaseType, checkType);
}
else
{
return false;
}
}
}

我认为其他一切只是VisualStudio和设计师的内容。我可能错了，但这应该让我知道我的情况。
