SpinLock(Boolean) 构造函数

定义

命名空间:
System.Threading
程序集:
mscorlib.dll, System.Threading.dll
程序集:
mscorlib.dll
程序集:
System.Threading.dll
程序集:
netstandard.dll

使用用于跟踪线程 ID 以改进调试的选项初始化结构的新实例 SpinLock 。

public:
 SpinLock(bool enableThreadOwnerTracking);
public SpinLock(bool enableThreadOwnerTracking);
new System.Threading.SpinLock : bool -> System.Threading.SpinLock
Public Sub New (enableThreadOwnerTracking As Boolean)

参数

enableThreadOwnerTracking
Boolean

是否捕获和使用线程 ID 进行调试。

示例

以下示例演示如何使用 SpinLock。

// C#
public class MyType
{
    private SpinLock _spinLock = new SpinLock();

    public void DoWork()
    {
        bool lockTaken = false;
        try
        {
           _spinLock.Enter(ref lockTaken);
           // do work here protected by the lock
        }
        finally
        {
            if (lockTaken) _spinLock.Exit();
        }
    }
}

' Visual Basic

Class MyType
   Private _spinLock As New SpinLock()

   Public Sub DoWork()
      Dim lockTaken As Boolean = False
      Try
         _spinLock.Enter(lockTaken)
         ' do work here protected by the lock
      Finally
         If lockTaken Then _spinLock.Exit()
      End Try
   End Sub
End Class

注解

用于跟踪线程所有权的 SpinLock 无参数构造函数。
