DBProviderInfos.GetEnumerator 方法

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

返回用于遍历 DBProviderInfos 集合的枚举器。

public:
 Microsoft::SqlServer::Dts::Runtime::DBProviderInfoEnumerator ^ GetEnumerator();

public Microsoft.SqlServer.Dts.Runtime.DBProviderInfoEnumerator GetEnumerator ();

override this.GetEnumerator : unit -> Microsoft.SqlServer.Dts.Runtime.DBProviderInfoEnumerator

Public Function GetEnumerator () As DBProviderInfoEnumerator

返回

DBProviderInfoEnumerator

一个 DBProviderInfoEnumerator 枚举器。

示例

下面的代码示例使用 GetEnumerator 方法创建 ，DBProviderInfoEnumerator然后循环访问 集合。

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

namespace DBProvInfos_GetEnum  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            Application app = new Application();  
            DBProviderInfos dbprovInfos = app.DBProviderInfos;  

            //Create the Enumerator.  
            DBProviderInfoEnumerator myEnumerator = dbprovInfos.GetEnumerator();  
            Console.WriteLine("The collection contains the following values:");  
            int i = 0;  
            while ((myEnumerator.MoveNext()) && (myEnumerator.Current != null))  
                Console.WriteLine("[{0}] {1}", i++, myEnumerator.Current.Name);  
        }  
    }  
}  

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

Namespace DBProvInfos_GetEnum  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            Dim app As Application =  New Application()   
            Dim dbprovInfos As DBProviderInfos =  app.DBProviderInfos   

            'Create the Enumerator.  
            Dim myEnumerator As DBProviderInfoEnumerator =  dbprovInfos.GetEnumerator()   
            Console.WriteLine("The collection contains the following values:")  
            Dim i As Integer =  0   
            While (myEnumerator.MoveNext()) &&(myEnumerator.Current <> Nothing)  
            Console.WriteLine("[{0}] {1}",i = Console.WriteLine("[{0}] {1}",i + 1  
            End While  
        End Sub  
    End Class  
End Namespace
