DbKey Class

Represents the connection information to a database for a CodeFirst model.

Syntax

Visual Basic
C#

'Declaration
 
<SerializableAttribute()>
Public Class DbKey 
   Inherits EdmKey
   Implements IdeaBlade.EntityModel.IDataSourceKey

'Usage
 
Dim instance As DbKey

[Serializable()]
public class DbKey : EdmKey, IdeaBlade.EntityModel.IDataSourceKey

Remarks

By default a DbKey is created from the connection information for a matching element in the ConnectionStrings section of your configuration file. You can override this default by specifying an EdmKey in the IdeaBlade section of the configuration file. You can also create an EdmKey at run-time by implementing a custom IdeaBlade.EntityModel.IDataSourceKeyResolver.

An DbKey differs from an EdmKey in that its connection string does not contain EDMX metadata information because a design-time model is not used. As with the EdmKey, the DbKey is used on only the server; your client application should use a ClientEdmKey when working with data source keys.

If the database does not exist or has changed it will be created when the DbKey is constructed, depending on the IDatabaseInitializer strategy in effect.
