示例1: AcquireReadWriteLocks_ReadWrite_Blocks
public void AcquireReadWriteLocks_ReadWrite_Blocks()
{
var name = Guid.NewGuid().ToString();
using (var sma = new Array<byte>(name, 10))
{
using (var smr = new Array<byte>(name))
{
// Acquire write lock
sma.AcquireWriteLock();
// Should block (and fail to reset write signal)
Assert.IsFalse(smr.AcquireReadLock(10));
sma.ReleaseWriteLock();
smr.AcquireReadLock();
// Should block (and fail to reset read signal)
Assert.IsFalse(sma.AcquireWriteLock(10));
smr.ReleaseReadLock();
}
}
