Gendarme.Rules.Correctness.FinalizersShouldCallBaseClassFinalizerRule(2.10)

FinalizersShouldCallBaseClassFinalizerRule

Assembly: Gendarme.Rules.Correctness
Version: 2.10

Description

This rule is used to warn the developer that a finalizer does not call the base class finalizer. In C#, this is enforced by compiler but some .NET languages (like IL) may allow such behavior.

Examples

Bad example (IL):

.assembly extern mscorlib
{
    .ver 1:0:5000:0
    .publickeytoken = (B7 7A 5C 56 19 34 E0 89 )
}
.class public auto ansi beforefieldinit BadFinalizer extends [mscorlib]System.Object
{
    .method family virtual hidebysig instance void Finalize() cil managed
    {
        // no base call so rule will fire here
    }
}

Good example (C#):

public class GoodFinalizer {
    ~GoodFinalizer ()
    {
        // C# compiler will insert base.Finalize () call here
        // so any compiler-generated code will be valid
    }
}
