Singulink.Threading.ReadWriteGuard provides disposable guards for ReaderWriterLockSlim that simplify entering and reliably exiting locks by allowing you to use the using statement.

We are a small team of engineers and designers dedicated to building beautiful, functional and well-engineered software solutions. We offer very competitive rates as well as fixed-price contracts and welcome inquiries to discuss any custom development / project support needs you may have.

This package is part of our Singulink Libraries collection. Visit https://github.com/Singulink to see our full list of publicly available libraries and other open-source projects.

Simply install the Singulink.Threading.ReadWriteGuard package from NuGet into your project.

Supported Runtimes: Anywhere .NET Standard 2.0+ is supported, including:

• .NET Core 2.0+
• .NET Framework 4.6.1+
• Mono 5.4+
• Xamarin.iOS 10.14+
• Xamarin.Android 8.0+

When you import the Singulink.Threading namespace, 3 new extension methods appear on ReaderWriterLockSlim instances:

• EnterReadGuard()
• EnterWriteGuard()
• EnterUpgradeableReadGuard()

You can view the API on FuGet.

var lock = new ReaderWriterLockSlim();

// Locks are acquired inside the using blocks and released at the end:

using (lock.EnterReadGuard())
{
    // Safe to read here
    ReadData();
}

using (lock.EnterWriteGuard())
{
    // Safe to write here
    WriteData();
}

using (var upgradeableGuard = lock.EnterUpgradeableReadGuard())
{
    // Safe to read here
    ReadData();

    if (someCondition)
    {
        upgradeableGuard.UpgradeToWriteGuard();
        // Safe to write here
        WriteData();
    }
}
