ReaderWriterLockSlim.WaitingReadCount 属性

定义

命名空间:

System.Threading

程序集:

System.Threading.dll

Source:

ReaderWriterLockSlim.cs

获取等待进入读取模式锁定状态的线程总数。

public:
 property int WaitingReadCount { int get(); };

public int WaitingReadCount { get; }

member this.WaitingReadCount : int

Public ReadOnly Property WaitingReadCount As Integer

属性值

Int32

等待进入读取模式的线程总数。

示例

以下示例演示如何在被阻止的线程数（等待进入读取模式）超过阈值时使用 WaitingReadCount 属性生成事件日志条目。

using (ReaderWriterLockSlim rwLock = new ReaderWriterLockSlim()) {

Using rwLock As New ReaderWriterLockSlim()

int waitingReadCt = rwLock.WaitingReadCount;
if (waitingReadCt > READ_THRESHOLD)
{
    performanceLog.WriteEntry(String.Format(
        "{0} blocked reader threads; exceeds recommended maximum.", 
        waitingReadCt));
}

Dim waitingReadCt As Integer = rwLock.WaitingReadCount
If waitingReadCt > READ_THRESHOLD Then
    performanceLog.WriteEntry(String.Format( _
        "{0} blocked reader threads; exceeds recommended maximum.", _
        waitingReadCt))
End If

注解

此属性仅用于调试、分析和日志记录目的，而不用于控制算法的行为。 结果一经计算就可更改。 因此，基于此属性做出决策是不安全的。
