==== Noncompliant code example

[source,csharp,diff-id=1,diff-type=noncompliant]
----
[Serializable]
public class Foo
{
    [OnSerializing]
    public void OnSerializing(StreamingContext context) {} // Noncompliant: should be private

    [OnSerialized]
    int OnSerialized(StreamingContext context) {} // Noncompliant: should return void

    [OnDeserializing]
    void OnDeserializing() {} // Noncompliant: should have a single parameter of type StreamingContext

    [OnSerializing]
    public void OnSerializing2<T>(StreamingContext context) {} // Noncompliant: should have no type parameters

    [OnDeserialized]
    void OnDeserialized(StreamingContext context, string str) {} // Noncompliant: should have a single parameter of type StreamingContext
}

==== Compliant solution

[source,csharp,diff-id=1,diff-type=compliant]
----
[Serializable]
public class Foo
{
    [OnSerializing]
    private void OnSerializing(StreamingContext context) {}

    [OnSerialized]
    private void OnSerialized(StreamingContext context) {}

    [OnDeserializing]
    private void OnDeserializing(StreamingContext context) {}

    [OnDeserialized]
    private void OnDeserialized(StreamingContext context) {}
}
