Beispiele
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;
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);
}
}
}

Dim app As Application = New Application()
Dim pkg As Package = app.LoadPackage(mySample,Nothing)
' Get the LogProviders collection from the package.
Dim logProvs As LogProviders = pkg.LogProviders
'Create the Enumerator.
Dim myEnumerator As LogProviderEnumerator = logProvs.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
Sample Output:
The collection contains the following values:
[0] SSIS log provider for Text files
