C#多线程编程之使用ReaderWriterLock类实现多用户读与单用户写同步

System.Console.ReadKey(); }

//读数据 static void Read()

{ for (int i = 0; i < 3; i++)

{ try

{ //申请读操作锁，如果在1000ms内未获取读操作锁，则放弃

rwl.AcquireReaderLock(1000); Console.WriteLine("开始读取数据，theResource = {0}", theResource);

Thread.Sleep(10); Console.WriteLine("读取数据结束，theResource = {0}", theResource);

//释放读操作锁 rwl.ReleaseReaderLock();

} catch (ApplicationException)

{ //获取读操作锁失败的处理

} }

} //写数据

static void Write() {

for (int i = 0; i < 3; i++) {

try {

//申请写操作锁，如果在1000ms内未获取写操作锁，则放弃 rwl.AcquireWriterLock(1000);

Console.WriteLine("开始写数据，theResource = {0}", theResource); //将theResource加1

theResource++; Thread.Sleep(100);

Console.WriteLine("写数据结束，theResource = {0}", theResource); //释放写操作锁

rwl.ReleaseWriterLock(); }

catch (ApplicationException) {

//获取写操作锁失败 }

} }
