通过

SpinLock(Boolean) 构造函数

  • 参考

定义

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

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

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

是否捕获线程 ID 并将其用于调试目的。

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 SpinLock 跟踪线程所有权的无参数构造函数。
