C#Copy Code
using (DebugLocking<SimpleReadWriteLocking> l = new DebugLocking<SimpleReadWriteLocking>(
    false, 0, 1, false, 1))
{
    Assert.IsFalse(l.CaptureStack);

    Assert.AreEqual(0, l.CurrentReaderCount);
    Assert.AreEqual(0, l.LocalReaderCount);
    Assert.AreEqual(0, l.MaxReaderCount);

    using (l.Read())
    {
        Assert.AreEqual(1, l.CurrentReaderCount);
        Assert.AreEqual(1, l.LocalReaderCount);
        using (l.Read(0))
        {
            Assert.AreEqual(2, l.CurrentReaderCount);
            Assert.AreEqual(2, l.LocalReaderCount);
        }
    }

    Assert.AreEqual(0, l.CurrentReaderCount);
    Assert.AreEqual(0, l.LocalReaderCount);
    Assert.AreEqual(2, l.MaxReaderCount);
}
VB.NETCopy Code
Using l As New DebugLocking(Of SimpleReadWriteLocking)(False, 0, 1, False, 1)
    Assert.IsFalse(l.CaptureStack)

    Assert.AreEqual(0, l.CurrentReaderCount)
    Assert.AreEqual(0, l.LocalReaderCount)
    Assert.AreEqual(0, l.MaxReaderCount)

    Using l.Read()
        Assert.AreEqual(1, l.CurrentReaderCount)
        Assert.AreEqual(1, l.LocalReaderCount)
        Using l.Read(0)
