ConnectionInfos.Contains(Object) 方法

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

返回一个布尔值，该值指示是否可以 ConnectionInfo 使用名称、索引、ID 或标识参数作为索引来访问集合中的 ConnectionInfos 项。

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

集合中要匹配的对象的名称、索引、ID 或标识。

返回

Boolean

true 指示可以使用语法 ConnectionInfos[index]检索项;false 指示索引不能用于从 ConnectionInfos 集合中检索项。

示例

以下示例演示了对连接“DTS 连接管理器 for Files”的集合的搜索。 搜索中使用的名称是在属性中 Name 返回的名称。

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
