挂起线程，或者如果线程已挂起，则不起作用。

例外

PlatformNotSupportedException

仅限 .NET Core 和 .NET 5 及更高版本：在所有情况下。

ThreadStateException

线程尚未启动或已终止。

SecurityException

调用方没有适当的 SecurityPermission。

注解

如果线程已挂起，则此方法不起作用。

注意

不要使用 Suspend 和 Resume 方法来同步线程的活动。 在挂起线程时，你无法知道线程正在执行什么代码。 如果在安全权限评估期间暂停某个线程，而该线程持有锁，则 中的 AppDomain 其他线程可能会被阻止。 如果在线程执行类构造函数时挂起该线程，则会阻止尝试 AppDomain 使用该类的其他线程。 死锁很容易发生。

在线程上调用 Suspend 方法时，系统会注意到已请求线程挂起，并允许线程执行，直到它到达安全点，然后再实际挂起线程。 线程的安全点是可以执行垃圾回收的执行点。 一旦达到安全点，运行时就会确保暂停的线程在托管代码中不会进一步取得任何进展。 在托管代码外部执行的线程始终都可以安全执行垃圾回收，并继续执行到尝试恢复执行托管代码。
