condition语句不起作用。我必须根据变量中提供的vm提供的数量创建执行扩展块。我正在使用此模板创建多个虚拟机。 我试过下面的条件代码，但没有运气。我想基于numberofvm变量值执行块。完整的模板代码如下。

我在部署时遇到错误。 '模板参考 'vm-nic-3'无效：找不到模板资源或资源 用此名称复制。请参阅 https://aka.ms/arm-template-expressions/#reference了解使用情况的详细信息。'。
答案 0 :(得分：2)
此错误与您的情况无关，它发生在其他地方，您引用了称为vm-nic-1的资源。它不存在，所以很可能叫做别的东西。
好吧，看着您的模板，我想我了解您要执行的操作，您正在尝试根据模板中的情况应用不同的扩展名。但是条件在评估模板后仍然有效，因此会出现此错误（对于3个vms，仅创建nic 0,1,2，它也在寻找nic 3和4）。解决此问题的最简单方法是将扩展名移至单独的资源，具体取决于vmloop，因此它不会在意创建了多少个vm，它还会为每个vm创建一个扩展名。如果您希望扩展中发生不同的事情，可以使用模板中的if()函数来定义它们。

ps。我从VM定义中删除了不起作用的部分，并且您的脚本扩展名定义也是错误的。
