Property Value

The name of the instance of SQL Server to which to connect. The default value is an empty string.

NoteNote:

  The DataSource property returns a null reference (Nothing in Visual Basic) if the connection string for the SqlConnection is "context connection=true".

The following example creates a SqlConnection and displays some of its read-only properties.

private static void OpenSqlConnection(string connectionString)
{
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        connection.Open();
        Console.WriteLine("ServerVersion: {0}", connection.ServerVersion);
        Console.WriteLine("DataSource: {0}", connection.DataSource);
    }
}
