DbConnectionStringBuilder.Keys Property

Gets an ICollection that contains the keys in the DbConnectionStringBuilder.

Namespace:  System.Data.Common
Assembly:  System.Data (in System.Data.dll)

[<BrowsableAttribute(false)>]
abstract Keys : ICollection
[<BrowsableAttribute(false)>]
override Keys : ICollection

Property Value

Type: System.Collections.ICollection
An ICollection that contains the keys in the DbConnectionStringBuilder.

Implements

IDictionary.Keys

The order of the values in the ICollection is unspecified, but it is the same order as the associated values in the ICollection returned by the Values property.

The returned ICollection is not a static copy; instead, the ICollection refers back to the keys in the original DbConnectionStringBuilder. Therefore, changes to the DbConnectionStringBuilder are reflected in the ICollection.

The following console application example creates a new DbConnectionStringBuilder, and adds some keys. The code loops through the ICollection returned by the Keys property displaying the key/value pairs, and then adds a new key. Because the Keys property returns a dynamic ICollection, the second loop displays all the key/value pairs, including the newest item.
