已更新的文本：2005 年 12 月 5 日

The value used for the connectionType parameter in this method is the value that is shown in the ConnectionManagerType property in the Designer. SQL Server (SSIS) includes several common connection types, including the following connection manager types:

• ADO for accessing Microsoft ActiveX Data Objects (ADO) objects

• ADO.NET for accessing ADO.NET objects

• FILE for accessing files

• FLATFILE for accessing data in flat files

• HTTP for accessing a Web server

• OLEDB for accessing relational data sources using OLE DB

• ODBC for accessing databases using ODBC

• Windows Management Instrumentation (WMI) for accessing a server and specifying the scope of management on the server

• FTP for accessing a server to send and receive files

• MSOLAP90 for accessing an instance of Microsoft SQL Server 2005 Analysis Services or an Analysis Services project

示例

The following code sample adds an ADO.NET connection manager to a package that contains two existing connections.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

namespace ConnMgr_GetEnum_Current
{
    class Program
    {
        static void Main(string[] args)
        {
            // The package is one of the SSIS Samples.
            string mySample = @"C:\Program Files\Microsoft SQL Server\90\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";
            // Create an application and load the sample.
            Application app = new Application();
            Package pkg = app.LoadPackage(mySample, null);

            // Get the Connections collection from the package.
            Connections conns = pkg.Connections;

            // Count the number of connections in the package.
            int myConns = conns.Count;
            Console.WriteLine("The number of connections is: {0}", myConns);

            //Add a new connection manager to the collection.
            conns.Add("ADO.NET");
            myConns = conns.Count;
            Console.WriteLine("The number of connections now is: {0}", myConns);
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace ConnMgr_GetEnum_Current
    Class Program
        Shared  Sub Main(ByVal args() As String)
            ' The package is one of the SSIS Samples.
            Dim mySample As String =  "C:\Program Files\Microsoft SQL Server\90\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx" 
            ' Create an application and load the sample.
            Dim app As Application =  New Application() 
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing) 
 
            ' Get the Connections collection from the package.
            Dim conns As Connections =  pkg.Connections 
 
            ' Count the number of connections in the package.
            Dim myConns As Integer =  conns.Count 
            Console.WriteLine("The number of connections is: {0}", myConns)
 
            'Add a new connection manager to the collection.
            conns.Add("ADO.NET")
            myConns = conns.Count
            Console.WriteLine("The number of connections now is: {0}", myConns)
        End Sub
    End Class
End Namespace

Sample Output:

The number of connections is: 2

The number of connections now is: 3
