Property Value

RunningPackage

A RunningPackage object.

Examples

The following code example creates an enumerator to iterate over the running packages.

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

namespace RunningPackages  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            Application app = new Application();  
            RunningPackages pkgs = app.GetRunningPackages("YOURSERVER");  

            int pkgsRunning = pkgs.Count;  
            Console.WriteLine("Packages before stop: " + pkgsRunning);  

            // Get the RunningPackages collection from the package.  
            RunningPackages runPkgs = app.GetRunningPackages("YOURSERVER ");  

            //Create the Enumerator.  
            RunningPackagesEnumerator myEnumerator = runPkgs.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.PackageDescription);  
        }  
    }  
}

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

Namespace RunningPackages  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            Dim app As Application =  New Application()   
            Dim pkgs As RunningPackages =  app.GetRunningPackages("YOURSERVER")   

            Dim pkgsRunning As Integer =  pkgs.Count   
            Console.WriteLine("Packages before stop: " + pkgsRunning)  

            ' Get the RunningPackages collection from the package.  
            Dim runPkgs As RunningPackages =  app.GetRunningPackages("YOURSERVER ")   

            'Create the Enumerator.  
            Dim myEnumerator As RunningPackagesEnumerator =  runPkgs.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

Remarks

After an enumerator is created, or after a call to the Reset method, the MoveNext method must be called to advance the enumerator to the first element of the collection before the enumerator can read the value of the Current property; otherwise, Current is undefined and throws an exception.

Current also throws an exception if the last call to MoveNext returned false, which indicates the end of the collection.

Current does not move the position of the enumerator, and consecutive calls to Current return the same object until either MoveNext or Reset is called.

An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is invalidated and becomes irrecoverable; thus, the next call to MoveNext or Reset throws an InvalidOperationException. However, if the collection is modified between calls to MoveNext and Current, Current returns the element that it is set to, even if the enumerator has been invalidated.
