AttributeArgumentsShouldHaveAccessorsRule

Assembly: Gendarme.Rules.Design
Version: git

Description

This rule fires if a parameter to an Attribute constructor is not exposed using a properly cased property. This is a problem because it is generally not useful to set state within an attribute without providing a way to get at that state.

Examples

Bad example:

[AttributeUsage (AttributeTargets.All)]
public sealed class AttributeWithRequiredProperties : Attribute {
    private int storedFoo;
    private string storedBar;
    // we have no corresponding property with the name 'Bar' so the rule will fail
    public AttributeWithRequiredProperties (int foo, string bar)
    {
        storedFoo = foo;
        storedBar = bar;
    }
    public int Foo {
        get {
            return storedFoo;
        }
    }
}

Good example:

[AttributeUsage (AttributeTargets.All)]
public sealed class AttributeWithRequiredProperties : Attribute {
    private int storedFoo;
    private string storedBar;
    public AttributeWithRequiredProperties (int foo, string bar)
    {
        storedFoo = foo;
        storedBar = bar;
    }
    public int Foo {
        get {
            return storedFoo;
        }
    }
    public string Bar {
        get {
            return storedBar;
        }
    }
}
