Question

我一直在讨论一个愚蠢的问题，当我尝试在特定命令中使用变量时，我得到一个错误，但是如果我使用实际的变量值而不是它的工作原理。为什么我不能在这里使用变量以及解决方法是什么？请帮忙。变量都具有正确的值。我确认一切正常，直到最后一行执行...

（此代码中的最后一行会引发错误...）

#####################################################################
# Prompt for user input regarding deleted and destination mailboxes #

显然import com.neomades.app.Application; import com.neomades.app.Controller; import java.util.ArrayList; import java.util.List; import org.junit.runner.JUnitCore; import org.junit.runner.Result; import org.junit.runner.notification.Failure; /** * Entry point */ public class UnitTestsApp extends Application { public void onStart(Controller controller) { // first screen controller.pushScreen(UnitTestsScreen.class); controller.runOnBackgroundThread(new Runnable(){ public void run() { List<Class> testCases = new ArrayList(); //Add test cases testCases.add(JSONConverterTests.class); JUnitCore core = new JUnitCore(); core.addListener(new TestRunListener()); for (Class testCase : testCases) { RunTestCase(testCase); } } }); } private static void RunTestCase(Class testCase) { Result result = JUnitCore.runClasses(testCase); } }是一个列表，而不是单个元素。从列表中选择一个元素：

$DeletedGUID

或在循环中运行New-MailboxRestoreRequest -SourceMailbox $DeletedGUID[0] ...：

New-MailboxRestoreRequest

另外，替换

$DeletedGUID | ForEach-Object {
  New-MailboxRestoreRequest -SourceMailbox $_ ...
}

与

...| Select ExchangeGUID | FT -HideTableHeaders

Select -Expand ExchangeGUID cmdlet用于输出格式，不适用于您想要进一步处理的内容。

命令抛出错误
