DTSReadOnlyCollectionBase.GetEnumerator DTSReadOnlyCollectionBase.GetEnumerator DTSReadOnlyCollectionBase.GetEnumerator Method

Definition

Returns an enumerator that can iterate through the DTSReadOnlyCollectionBase instance.

public:
 virtual System::Collections::IEnumerator ^ GetEnumerator();
public System.Collections.IEnumerator GetEnumerator ();
Public Function GetEnumerator () As IEnumerator

Returns

Returns an IEnumerator for the DTSReadOnlyCollectionBase instance.

Examples

The following code example uses the LogProviders class to demonstrate the use of GetEnumerator. The LogProviders collection inherits from DTSReadOnlyCollectionBase, and overrides the GetEnumerator to provide an appropriate enumerator for its collection.

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

    class Program  
    {  
        static void Main(string[] args)  
        {  
            // The package is one of the SSIS Samples. The package  
            // was modified in the designer to log to the SSIS log  
             // provider for Text files before being loaded  
            // for this code example.  
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";  
            // Create the Application, and load the sample.  
            Application app = new Application();  
            Package pkg = app.LoadPackage(mySample, null);  
  
            // Get the LogProviders collection from the package.  
            LogProviders logProvs = pkg.LogProviders;  
  
            //Create the Enumerator.  
            LogProviderEnumerator myEnumerator = logProvs.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);  
        }  
    }  
}

            End While

Sample Output:

The collection contains the following values:

[0] SSIS log provider for Text files
