示例
以下示例演示导致系统引发 的错误 ThreadStateException
。
using namespace System;
using namespace System::Threading;
ref class ThreadWork
{
public:
static void DoWork()
{
Console::WriteLine( "Working thread..." );
}
};
int main()
{
ThreadStart^ myThreadDelegate = gcnew ThreadStart( ThreadWork::DoWork );
Thread^ myThread = gcnew Thread( myThreadDelegate );
myThread->Start();
Thread::Sleep( 0 );
Console::WriteLine( "In main. Attempting to restart myThread." );
try
{
myThread->Start();
}
catch ( ThreadStateException^ e )
{
Console::WriteLine( "Caught: {0}", e->Message );
}
}
using System;
using System.Threading;
public class ThreadWork
{
public static void DoWork()
{
Console.WriteLine("Working thread...");
}
}
class ThreadStateTest
{
public static void Main()
{
ThreadStart myThreadDelegate = new ThreadStart(ThreadWork.DoWork);
Thread myThread = new Thread(myThreadDelegate);
myThread.Start();
Thread.Sleep(0);
Console.WriteLine("In main. Attempting to restart myThread.");
try
{
myThread.Start();
}
catch (ThreadStateException e)
{
Console.WriteLine("Caught: {0}", e.Message);
}
}
}
Imports System.Threading
Public Class ThreadWork
Public Shared Sub DoWork()
Console.WriteLine("Working thread...")
End Sub
End Class
Class ThreadStateTest
Public Shared Sub Main()
Dim myThreadDelegate As New ThreadStart(AddressOf ThreadWork.DoWork)
Dim myThread As New Thread(myThreadDelegate)
myThread.Start()
Thread.Sleep(0)
Console.WriteLine("In main. Attempting to restart myThread.")
Try
myThread.Start()
Catch e As ThreadStateException
Console.WriteLine("Caught: {0}", e.Message)
End Try
End Sub
End Class
此代码生成以下输出:
In main. Attempting to restart myThread.
Working thread...
Caught: Thread is running or terminated. Cannot restart.
注解
创建线程后,它至少处于其中一种状态, ThreadState 直到它终止。 ThreadStateException
由由于线程的当前状态而无法执行所请求操作的方法引发。 例如,尝试通过在已终止的线程上调用 Start 来重启中止的线程会 ThreadStateException引发 。
ThreadStateException 使用 HRESULT COR_E_THREADSTATE,其值0x80131520。
有关实例的初始属性值的列表ThreadStateException,请参阅ThreadStateException构造函数。
构造函数
ThreadStateException() |
使用默认属性初始化 ThreadStateException 类的新实例。 |
ThreadStateException(SerializationInfo, StreamingContext) |
用序列化数据初始化 ThreadStateException 类的新实例。 |
ThreadStateException(String) |
用指定的错误消息初始化 ThreadStateException 类的新实例。 |
ThreadStateException(String, Exception) |
使用指定的错误消息和对作为此异常原因的内部异常的引用来初始化 ThreadStateException 类的新实例。 |
属性
Data |
获取键/值对的集合,这些键/值对提供有关该异常的其他用户定义信息。 (继承自 Exception) |
HelpLink |
获取或设置指向与此异常关联的帮助文件链接。 (继承自 Exception) |
HResult |
获取或设置 HRESULT(一个分配给特定异常的编码数字值)。 (继承自 Exception) |
InnerException |
获取导致当前异常的 Exception 实例。 (继承自 Exception) |
Message |
获取描述当前异常的消息。 (继承自 Exception) |
Source |
获取或设置导致错误的应用程序或对象的名称。 (继承自 Exception) |
StackTrace |

方法
Equals(Object) |
确定指定对象是否等于当前对象。 (继承自 Object) |

ToString() |
创建并返回当前异常的字符串表示形式。 (继承自 Exception) |
事件
SerializeObjectState |
已过时.
当异常被序列化用来创建包含有关该异常的徐列出数据的异常状态对象时会出现该问题。 (继承自 Exception) |
