DtsProperties.GetEnumerator 方法

定义

返回枚举器,用于迭代集合 DtsProperties

public:
 Microsoft::SqlServer::Dts::Runtime::PropertyEnumerator ^ GetEnumerator();
public Microsoft.SqlServer.Dts.Runtime.PropertyEnumerator GetEnumerator();
override this.GetEnumerator : unit -> Microsoft.SqlServer.Dts.Runtime.PropertyEnumerator
Public Function GetEnumerator () As PropertyEnumerator

返回

一个用于迭代集合 DtsProperties 的枚举器。

示例

以下代码示例创建了 PropertyEnumerator,然后展示了 和 Current 方法在集合上的移动MoveNext方式。

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

namespace DtsProperties_API  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            Package pkg = new Package();  

            // Get the Properties collection from the package.  
            // This shows the default properties set on new packages.  
            DtsProperties pkgProperties = pkg.Properties;  

           // Create the enumerator.  
            PropertyEnumerator myEnumerator = pkgProperties.GetEnumerator();  

            // Show the use of the Contains method.  
            Boolean containsCertObj = pkgProperties.Contains("CertificateObject");  
            Console.WriteLine("Contains CertificateObject? {0}", containsCertObj);  

            // Show the use of the item[x] syntax.  
            String aName = pkgProperties[5].Name;  
            Console.WriteLine("Property 5 is {0}", aName);  

            // Show the use of the MoveNext and Current methods.  
            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 DtsProperties_API  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            Dim pkg As Package =  New Package()   

            ' Get the Properties collection from the package.  
            ' This shows the default properties set on new packages.  
            Dim pkgProperties As DtsProperties =  pkg.Properties   

           ' Create the enumerator.  
            Dim myEnumerator As PropertyEnumerator =  pkgProperties.GetEnumerator()   

            ' Show the use of the Contains method.  
            Dim containsCertObj As Boolean =  pkgProperties.Contains("CertificateObject")   
            Console.WriteLine("Contains CertificateObject? {0}", containsCertObj)  

            ' Show the use of the item[x] syntax.  
            Dim aName As String =  pkgProperties(5).Name   
            Console.WriteLine("Property 5 is {0}", aName)  

            ' Show the use of the MoveNext and Current methods.  
            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
