CA1513: Use ObjectDisposedException throw helper - .NET

Code checks if an object is disposed and then conditionally throws an ObjectDisposedException.

Object checks have a substantial impact on code size and often dominate the code for small functions and property setters. These checks prevent inlining and cause substantial instruction-cache pollution. Throw-helper methods such as ThrowIf are simpler and more efficient than if blocks that construct a new exception instance.

The following code snippet shows a violation of CA1513:

class C
{
    private bool _disposed = false;
    void M()
    {
        if (_disposed)
            throw new ObjectDisposedException(GetType().Name);
    }
}

The following code snippet shows the fix:

class C
{
    private bool _disposed = false;
    void M()
    {
        ObjectDisposedException.ThrowIf(_disposed, this);
    }
}

Replace the if block that throws the exception with a call to ThrowIf. Or, in Visual Studio, use the lightbulb menu to fix your code automatically.

It's safe to suppress a violation of this rule if you're not concerned about the maintainability of your code. It is also fine to suppress violations that are identified to be false positives.

If you just want to suppress a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

#pragma warning disable CA1513
// The code that's violating the rule is on this line.
#pragma warning restore CA1513

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.

[*.{cs,vb}]
dotnet_diagnostic.CA1513.severity = none
