DTSReadOnlyCollectionBase インスタンスに含まれる要素の数を取得します。

名前空間:  Microsoft.SqlServer.Dts.Runtime
アセンブリ:  Microsoft.SqlServer.ManagedDTS (Microsoft.SqlServer.ManagedDTS.dll)

構文

'宣言
Public ReadOnly Property Count As Integer
    Get
'使用
Dim instance As DTSReadOnlyCollectionBase
Dim value As Integer

value = instance.Count

public int Count { get; }

public:
virtual property int Count {
    int get () sealed;
}

abstract Count : int
override Count : int

final function get Count () : int

プロパティ値

型: System. . :: . .Int32
DTSReadOnlyCollectionBase インスタンスに含まれる要素の数を表す整数です。

実装

ICollection. . :: . .Count

使用例

次のコード例は、継承クラスである LogProviders コレクションで Count プロパティを使用する方法を示しています。

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

namespace LogProviders_Tests
{
    class Program
    {
        static void Main(string[] args)
        {
            // The package is one of the SSIS Samples.
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx";

            // Create the Application, and load the sample.
            Application app = new Application();
            Package pkg = app.LoadPackage(mySample, null);
            LogProviders logProvs = pkg.LogProviders;

            // Count the number of providers in the package.
            int countProvs = logProvs.Count;
            Console.WriteLine("Initial number of log providers: {0}", countProvs);

            // Since the package that was loaded only contained the
            // SSIS Log provider for Text files, let's add the SQL
            // Server log provider.
            LogProvider logProv = pkg.LogProviders.Add("DTS.LogProviderSQLServer.2");

            // Count how many log providers are in the collection now.
            countProvs = logProvs.Count;
            Console.WriteLine("The number of log providers now: {0}", countProvs);
            Console.WriteLine("----------------------------");

            foreach (LogProvider lp in logProvs)
            {
                Console.WriteLine("Log Provider Name: {0}", lp.Name);
            }
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace LogProviders_Tests
    Class Program
        Shared  Sub Main(ByVal args() As String)
            ' The package is one of the SSIS Samples.
            Dim mySample As String =  "C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx" 
 
            ' Create the Application, and load the sample.
            Dim app As Application =  New Application() 
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing) 
            Dim logProvs As LogProviders =  pkg.LogProviders 
 
            ' Count the number of providers in the package.
            Dim countProvs As Integer =  logProvs.Count 
            Console.WriteLine("Initial number of log providers: {0}", countProvs)
 
            ' Since the package that was loaded only contained the
            ' SSIS Log provider for Text files, let's add the SQL
            ' Server log provider.
            Dim logProv As LogProvider =  pkg.LogProviders.Add("DTS.LogProviderSQLServer.2") 
 
            ' Count how many log providers are in the collection now.
            countProvs = logProvs.Count
            Console.WriteLine("The number of log providers now: {0}", countProvs)
            Console.WriteLine("----------------------------")
 
            Dim lp As LogProvider
            For Each lp In logProvs
                Console.WriteLine("Log Provider Name: {0}", lp.Name)
            Next
        End Sub
    End Class
End Namespace

サンプルの出力 :

Initial number of log providers: 1

The number of log providers now: 2

----------------------------

Log Provider Name: {FCA3ACD4-C080-4B67-A1AA-45118D3DA672}

Log Provider Name: SSIS log provider for Text files
