Description

Do not throw exceptions in special methods such as ToString(), Dispose() or GetHashCode.

Non-Compliant Code Examples

class MyClass {
    public override string GetHashCode()
    {
        if (something)
        {
            throw new Exception();
        }
        throw new Exception();
    }
}

class MyClass {
    public override string ToString()
    {
        if (something)
        {
            throw new Exception();
        }
        throw new Exception();
    }
}

Compliant Code Examples

class MyClass {
    // Safe: no exceptions thrown in special methods
    public override string ToString()
    {
        return "MyClass instance";
    }

    public override int GetHashCode()
    {
        return base.GetHashCode();
    }
}
