Question

我在第50行和第89行遇到“空跳过参数已传递到参数位置1”错误，我想将目标/源模块名称放入跳过列表。我知道循环仅在分别有out / in链接时才执行，那么它怎么有null参数呢？我还检查模块名称是否为空，但是该检查不会使错误框弹出。两个循环都针对一定数量的对象执行，然后在到达不喜欢的特定点时停止。任何提示将不胜感激。

这是一个非常简单的问题-

我要进行的更改-替换为：

delete(OinLinks)        //reset the OinLinks list so we can start fresh for the next object     
delete(OoutLinks)       //reset the OoutLinks list so we can start fresh for the next object

与此：

    for count in OinLinks do //reset the OinLinks list so we can start fresh for the next object     
    {
        delete ( OinLinks , ( string key OinLinks ) )
    }

    for count in OoutLinks do //reset the OoutLinks list so we can start fresh for the next object
    {
        delete ( OoutLinks , ( string key OoutLinks ) )
    }

作为每个对象循环的一部分，您正在删除整个跳过列表，而不是清空列表。这意味着在随后的循环中，程序无法找到“跳过”列表并抛出错误。最好重用跳过而不是每次都重新分配它们，但是您必须清空内容，而不是在跳过句柄上调用delete。

祝你好运，如果还有其他问题，请告诉我！
