Public Shared ReadOnly Property Instance As SqlDataSourceEnumerator

Property Value

An instance of the SqlDataSourceEnumerator used to retrieve information about available SQL Server instances.

Examples

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.

Imports System.Data.Sql  

Module Module1  
  Sub Main()  
    ' Retrieve the enumerator instance, and  
    ' then retrieve the data sources.  
    Dim instance As SqlDataSourceEnumerator = _  
     SqlDataSourceEnumerator.Instance  
    Dim table As System.Data.DataTable = instance.GetDataSources()  

    ' Filter the sources to just show SQL Server 2005 instances.  
    Dim rows() As DataRow = table.Select("Version LIKE '9%'")  
    For Each row As DataRow In rows  
      Console.WriteLine(row("ServerName"))  
    Next  
    Console.WriteLine("Press any key to continue.")  
    Console.ReadKey()  
  End Sub  
End Module  

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();  
  }  
}  

Remarks

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