SqlDataSourceEnumerator.Instance Property

Gets an instance of the SqlDataSourceEnumerator, which can be used to retrieve information about available SQL Server instances.

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

public static SqlDataSourceEnumerator Instance { get; }

The SqlDataSourceEnumerator class does not provide a constructor. Use the Instance property to retrieve an instance of the class instead.

The following console application displays a list of all the available SQL Server 2005 instances within the local network. This code uses the Select method to filter the rows in the table returned by the GetDataSources method.

using System.Data.Sql;

class Program
{
  static void Main()
  {
    // Retrieve the enumerator instance, and
    // then retrieve the data sources.
    SqlDataSourceEnumerator instance =
      SqlDataSourceEnumerator.Instance;
    System.Data.DataTable table = instance.GetDataSources();

    // Filter the sources to just show SQL Server 2005 instances.
    System.Data.DataRow[] rows = table.Select("Version LIKE '9%'");
    foreach (System.Data.DataRow row in rows)
    {
      Console.WriteLine(row["ServerName"]);
    }
    Console.WriteLine("Press any key to continue.");
    Console.ReadKey();
  }
}
