返回一个布尔值，指示集合中的项ConnectionInfos是否ConnectionInfo可以通过使用名称、索引、ID或身份参数作为索引访问。

public:
 bool Contains(System::Object ^ index);

public bool Contains(object index);

member this.Contains : obj -> bool

Public Function Contains (index As Object) As Boolean

参数

index

Object

集合中对象的名称、索引、ID 或身份，以匹配。

返回

Boolean

true表示您可以使用语法ConnectionInfos[index]检索该项;false 表示索引不能用于从集合中检索项目 ConnectionInfos 。

示例

以下示例展示了对“DTS 连接管理器 for Files”连接的搜索。 搜索中使用的名称即为物业中返回的 Name 名称。

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

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

            // Search for the File connection in the collection  
            if (connectionInfos.Contains("DTS Connection Manager for Files"))  
                Console.WriteLine("The collection contains the FILE connection");  
            else  
                Console.WriteLine("The collection does not contain the FILE connection");  
            Console.WriteLine();  
        }  
    }  
}  

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

Namespace ConnInfosTest  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            Dim dtsApplication As Application =  New Application()   
            Dim connectionInfos As ConnectionInfos =  dtsApplication.ConnectionInfos   

            ' Search for the File connection in the collection  
            If connectionInfos.Contains("DTS Connection Manager for Files") Then  
                Console.WriteLine("The collection contains the FILE connection")  
            Else   
                Console.WriteLine("The collection does not contain the FILE connection")  
            End If  
            Console.WriteLine()  
        End Sub  
    End Class  
End Namespace  

示例输出：

The collection contains the FILE connection
