예제

다음 예제에서는 모든 공급자의 데이터 원본을 열거할 수 있는 코드를 사용하여 사용 가능한 모든 SQL Server 데이터 원본 목록을 표시합니다.

using System;
using System.Data;
using System.Data.Common;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        // List all SQL Server instances:
        ListServers(SqlClientFactory.Instance);

        Console.WriteLine();
        Console.WriteLine("Press any key to continue...");
        Console.ReadKey();
    }
    private static void ListServers(DbProviderFactory factory)
    {
        // This procedure is provider-agnostic, and can list
        // instances of any provider's servers. Of course,
        // not all providers can create a data source enumerator,
        // so it's best to check the CanCreateDataSourceEnumerator
        // property before attempting to list the data sources.
        if (factory.CanCreateDataSourceEnumerator)
        {
            DbDataSourceEnumerator instance =
                factory.CreateDataSourceEnumerator();
