ConnectionInfos.Item[Object] 屬性

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

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

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

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

參數

屬性值

集合中一個 ConnectionInfo 與參數中 index 名稱、索引、ID 或身份相符的物件。

範例

以下程式碼範例是透過兩種方法從集合中取得一個項目。 第一種方法是利用語 connectionInfos[0] 法擷取位於集合首位的整個物件，然後將其放入物件中 connInfo 。 你現在可以像平常一樣從物件中取得所有屬性 ConnectionInfo 。 第二種方法是從集合中的第一個物件取得特定屬性。

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

namespace ConnectionInfos_GetEnum  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            Application dtsApplication = new Application();  
            ConnectionInfos connectionInfos = dtsApplication.ConnectionInfos;  

            //Using the Item method syntax of [x], obtain the first entry and a name.  
            ConnectionInfo connInfo = connectionInfos[0];  
            String nameOfFirstItem = connectionInfos[0].Name;  

            //Print the name of the log provider object located at position [0].  
            Console.WriteLine("The ID of the first connection info is: {0}", connInfo.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 ConnectionInfos_GetEnum  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            Dim dtsApplication As Application =  New Application()   
            Dim connectionInfos As ConnectionInfos =  dtsApplication.ConnectionInfos   

            'Using the Item method syntax of [x], obtain the first entry and a name.  
            Dim connInfo As ConnectionInfo =  connectionInfos(0)   
            Dim nameOfFirstItem As String =  connectionInfos(0).Name   

            'Print the name of the log provider object located at position [0].  
            Console.WriteLine("The ID of the first connection info is: {0}", connInfo.ID)  
            Console.WriteLine("The Name of the first connection info is: {0}", nameOfFirstItem)  

        End Sub  
    End Class  
End Namespace  

範例輸出：

The ID of the first connection info is: {41F5EFE4-E91A-4EB0-BF10-D40FD48B3C03}

The Name of the first connection info is: DTS Connection Manager for Files

備註

如果呼叫 Contains 方法回傳 true，你可以透過語法 ConnectionInfos[index]存取集合中指定的元素。 若方法 Contains 回傳 false，此特性會拋出例外。 在 C# 中，這個屬性就是類別的 ConnectionInfos 索引器。
