推荐答案

首先，您应该学习如何使用Visual Studio调试器。您可以在抛出异常的行上放置一个断点，然后从Visual Studio运行该应用程序。

First, you should learn how to use the Visual Studio debugger. You could put a breakpoint on the line that throws the exception and then run the app from Visual Studio.

其次，您的测试只是检查reqFields字符串中是否有任何字符串数组为null或空。如果是，则抛出异常。

Second, your test is simply checking to see if any of the strings in the reqFields string array are null or empty. If they are then the exception is thrown.

这是你的意图吗？
