示例1: ReaderWriterLock
// The complete code is located in the ReaderWriterLock class topic.
using System;
using System.Threading;
public class Example
{
static ReaderWriterLock rwl = new ReaderWriterLock();
// Define the shared resource protected by the ReaderWriterLock.
static int resource = 0;

示例2: UpgradeDowngrade
// Requests a reader lock, upgrades the reader lock to the writer
// lock, and downgrades it to a reader lock again.
static void UpgradeDowngrade(int timeOut)
{
try {
rwl.AcquireReaderLock(timeOut);
try {
// It's safe for this thread to read from the shared resource.
Display("reads resource value " + resource);
Interlocked.Increment(ref reads);
// To write to the resource, either release the reader lock and
// request the writer lock, or upgrade the reader lock. Upgrading
// the reader lock puts the thread in the write queue, behind any
// other threads that might be waiting for the writer lock.
try {
LockCookie lc = rwl.UpgradeToWriterLock(timeOut);
try {
// It's safe for this thread to read or write from the shared resource.
resource = rnd.Next(500);
Display("writes resource value " + resource);
Interlocked.Increment(ref writes);
}
finally {
// Ensure that the lock is released.
rwl.DowngradeFromWriterLock(ref lc);
}
}
catch (ApplicationException) {
// The upgrade request timed out.
Interlocked.Increment(ref writerTimeouts);
}
// If the lock was downgraded, it's still safe to read from the resource.
Display("reads resource value " + resource);
Interlocked.Increment(ref reads);
}
finally {
// Ensure that the lock is released.
rwl.ReleaseReaderLock();
}
}
catch (ApplicationException) {
// The reader lock request timed out.
Interlocked.Increment(ref readerTimeouts);
}
}
