DbConnection.DataSource Property

Gets the name of the database server to which to connect.

Namespace:  System.Data.Common
Assembly:  System.Data (in System.Data.dll)
public abstract string DataSource { get; }

Property Value

Type: System.String
The name of the database server to which to connect. The default value is an empty string.

If the connection to the database is closed, the DataSource returns whatever is contained in the ConnectionString for the DataSource keyword. If the connection is open and the ConnectionString data source keyword's value starts with "|datadirectory|", the property returns whatever is contained in the ConnectionString for the DataSource keyword only. If the connection to the database is open, the property returns what the native provider returns for the DBPROP_INIT_DATASOURCE, and if that is empty, the native provider's DBPROP_DATASOURCENAME is returned.
