Switch.GetSupportedAttributes Method

Gets the custom attributes supported by the switch.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

protected internal virtual string[] GetSupportedAttributes()

Return Value

Type: System.String[]
A string array that contains the names of the custom attributes supported by the switch, or null if there no custom attributes are supported.

The default implementation for the GetSupportedAttributes method returns null. If a switch is added in a configuration file and custom attributes are specified that are not included in the string array returned by GetSupportedAttributes, a ConfigurationException is thrown when the switch is loaded.

Notes to Inheritors

When inheriting from the Switch class or a derived class, you can override the GetSupportedAttributes method to provide custom attributes for your class.

The following code sample shows an override of the GetSupportedAttributes method for a custom switch.

public class MySourceSwitch : SourceSwitch
{
    int sourceAttribute = 0;
    public MySourceSwitch(string n) : base(n) { }
    public int CustomSourceSwitchAttribute
    {
        get
        {
            foreach (DictionaryEntry de in this.Attributes)
                if (de.Key.ToString().ToLower() == "customsourceswitchattribute")
                    sourceAttribute = (int)de.Value;
            return sourceAttribute;
        }
        set { sourceAttribute = (int)value; }
    }

    protected override string[] GetSupportedAttributes()
    {
        return new string[] { "customsourceSwitchattribute" };
    }
}
