Замечания

All classes that inherit from the ConnectionManager contain the same properties and methods. However, each connection type has additional properties that are specific to that connection type. When you obtain a connection manager from the collection and iterate through the properties, all properties that are not found in the ConnectionManager class are properties that are specific to that connection. To set a property that is unique to the connection, but is not part of the ConnectionManager, such as the RetainSameConnection property found on several connections, use the following line of code:

ConnectionManager.Properties("RetainSameConnection") = True

For more information about the type of connections available, see Connection Managers.

Примеры

The following code example obtains the Properties collection from the first connection manager in the Connections collection using the index syntax of [0]. The sample then writes the names of the properties found in the Properties collection.

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

namespace ConnMgr_Properties_Collection
{
    class Program
    {
        static void Main(string[] args)
        {
            // The package is one of the SSIS Samples.
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\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);
            Connections myConns = pkg.Connections;

            // Get the Properties collection from the connection
            // manager and iterate through the properties, 
            // printing the property names.
            ConnectionManager myConnMgr = myConns[0];
            DtsProperties connProperties = myConnMgr.Properties;

            foreach (DtsProperty connProp in connProperties)
                Console.WriteLine(connProp.Name);
        }
    }
}

            Dim mySample As String =  "C:\Program Files\Microsoft SQL Server\100\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) 
            Dim myConns As Connections =  pkg.Connections 
 
            ' Get the Properties collection from the connection
            ' manager and iterate through the properties, 
            ' printing the property names.
            Dim myConnMgr As ConnectionManager =  myConns(0) 
            Dim connProperties As DtsProperties =  myConnMgr.Properties 
 
            Dim connProp As DtsProperty
            For Each connProp In connProperties
                Console.WriteLine(connProp.Name)
            Next
        End Sub
    End Class
