包含应用程序特定的信息的对象。
示例
下面的代码示例演示如何将信息传递给正在中止的线程。
using System;
using System.Threading;
class Test
{
public static void Main()
{
Thread newThread = new Thread(new ThreadStart(TestMethod));
newThread.Start();
Thread.Sleep(1000);
// Abort newThread.
Console.WriteLine("Main aborting new thread.");
newThread.Abort("Information from Main.");
// Wait for the thread to terminate.
newThread.Join();
Console.WriteLine("New thread terminated - Main exiting.");
}
static void TestMethod()
{
try
{
while(true)
{
Console.WriteLine("New thread running.");
Thread.Sleep(1000);
}
}
catch(ThreadAbortException abortException)
{
Console.WriteLine((string)abortException.ExceptionState);
}
}
}
Imports System.Threading
Public Class Test
<MTAThread> _
Shared Sub Main()
Dim newThread As New Thread(AddressOf TestMethod)
newThread.Start()
Thread.Sleep(1000)
' Abort newThread.
Console.WriteLine("Main aborting new thread.")
newThread.Abort("Information from Main.")
' Wait for the thread to terminate.
newThread.Join()
Console.WriteLine("New thread terminated - Main exiting.")
End Sub
Shared Sub TestMethod()
Try
While True
Console.WriteLine("New thread running.")
Thread.Sleep(1000)
End While
Catch abortException As ThreadAbortException
Console.WriteLine( _
CType(abortException.ExceptionState, String))
End Try
End Sub
End Class
注解
此属性返回的对象是通过 stateInfo 方法的 Abort 参数指定的。 此对象的确切内容和用法由应用程序定义;它通常用于传达对中止的线程有意义的信息。
