Connections.Item[Object] 属性

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

从 ConnectionManager 集合中获取一个 Connections 对象。

public:
 property Microsoft::SqlServer::Dts::Runtime::ConnectionManager ^ default[System::Object ^] { Microsoft::SqlServer::Dts::Runtime::ConnectionManager ^ get(System::Object ^ index); };

public Microsoft.SqlServer.Dts.Runtime.ConnectionManager this[object index] { get; }

member this.Item(obj) : Microsoft.SqlServer.Dts.Runtime.ConnectionManager

Default Public ReadOnly Property Item(index As Object) As ConnectionManager

参数

index

Object

要返回的 ConnectionManager 对象的名称、标识、ID 或索引。

属性值

ConnectionManager

来自集合的一个 ConnectionManager 对象。

示例

下面的代码示例使用两种方法从集合中检索项。 第一种方法使用 conns[0] 语法检索位于集合的第一位置的整个对象，并将其放入变量中 myConnMgr 。 现在可以像往常一样检索 myConnMgr 所有属性。 第二种方法使用 conns[0].<property> 语法从集合中的第一个对象检索特定属性。

using Microsoft.SqlServer.Dts.Runtime;  

namespace Connections_Item  
{  
    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\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx";  

            // Create an application and load the sample.  
            Application app = new Application();  
            Package pkg = app.LoadPackage(mySample, null);  
            Connections conns = pkg.Connections;  

            //Using the Item method syntax of [x], obtain the  
            // entire first entry, and then just the name.  
            ConnectionManager myConnMgr = conns[0];  
            String nameOfFirstItem = conns[0].Name;  

            //Print the name of the connection manager located at position [0].  
            Console.WriteLine("The ID of the first connection info is: {0}", myConnMgr.ID);  
            Console.WriteLine("The Name of the first connection info is: {0}", nameOfFirstItem);  
        }  
    }  
}  

Imports System  
Imports System.Collections.Generic  
Imports System.Text  
Imports Microsoft.SqlServer.Dts.Runtime  

Namespace Connections_Item  
    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\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx"   

            ' Create an application and load the sample.  
            Dim app As Application =  New Application()   
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing)   
            Dim conns As Connections =  pkg.Connections   

            'Using the Item method syntax of [x], obtain the  
            ' entire first entry, and then just the name.  
            Dim myConnMgr As ConnectionManager =  conns(0)   
            Dim nameOfFirstItem As String =  conns(0).Name   

            'Print the name of the connection manager located at position [0].  
            Console.WriteLine("The ID of the first connection info is: {0}", myConnMgr.ID)  
            Console.WriteLine("The Name of the first connection info is: {0}", nameOfFirstItem)  
        End Sub  
    End Class  
End Namespace  

示例输出：

The ID of the first connection info is: {B52C0D78-5402-4544-BFEC-2BE203900C91}

The Name of the first connection info is: Create_Execute_Process_Dest.sql

注解

如果对方法的 Contains 调用返回 true，则可以使用语法 Connections[index]访问集合中的指定元素。 Contains如果该方法返回false，此属性将引发异常。 在 C# 中，此属性是 Connections 类的索引器。
