true if the property is a key property for an element of the collection; otherwise, false. The default is false.

Examples

The following example shows how to use the IsKey property.

C#

[ConfigurationProperty("name", DefaultValue = "Contoso",
    IsRequired = true, IsKey = true)]
public string Name
{
    get
    {
        return (string)this["name"];
    }
    set
    {
        this["name"] = value;
    }
}

Remarks

The IsKey property applies only if the property you decorate is a collection. It does not have any effect if the property is not a collection. Multiple elements can be marked as IsKey.
