member this.Executables : Microsoft.SqlServer.Dts.Runtime.Executables

Public ReadOnly Property Executables As Executables

Nilai Properti

Executables

Sebuah Executables koleksi.

Penerapan

Executables

Contoh

Contoh kode berikut membuat ForEachLoop dan mengatur beberapa properti menggunakan Properties koleksi. Dua tugas ditambahkan ke Executables koleksi, dan batasan prioritas diletakkan di antaranya.

// Create the package.  
Package package = new Package();  
// Add variables.  
package.Variables.Add("Id", false, "User", 0);  

// Create ForEachLoop task  
Executables executables = package.Executables;  
ForEachLoop forEachLoop = executables.Add("STOCK:FOREACHLOOP") as ForEachLoop;  

// The ForEachLoop is a container. Add some task executables and  
// create a precedence constraint. The tasks can run when  
// certain conditions in the loop are met.  
TaskHost thLoopMail = (TaskHost)forEachLoop.Executables.Add("STOCK:SendMailTask");  
TaskHost thLoopInsert = (TaskHost)forEachLoop.Executables.Add("STOCK:BulkInsertTask");  
Executables loopExecs = forEachLoop.Executables;  
Console.WriteLine("Number of Executables in ForLoop: {0}", loopExecs.Count);  

// Like other containers, precedence constraints can be set on the  
// contained tasks.  
PrecedenceConstraint pc = forEachLoop.PrecedenceConstraints.Add((Executable)thLoopMail, thLoopInsert);  
PrecedenceConstraints pcs = forEachLoop.PrecedenceConstraints;  
Console.WriteLine("Number of precedence constraints: {0}", pcs.Count);  

' Create the package.  
Dim package As Package =  New Package()   
' Add variables.  
package.Variables.Add("Id", False, "User", 0)  

' Create ForEachLoop task  
Dim executables As Executables =  package.Executables   
Dim forEachLoop As ForEachLoop =  executables.Add("STOCK:FOREACHLOOP") as ForEachLoop   

' The ForEachLoop is a container. Add some task executables and  
' create a precedence constraint. The tasks can run when  
' certain conditions in the loop are met.  
Dim thLoopMail As TaskHost = CType(forEachLoop.Executables.Add("STOCK:SendMailTask"), TaskHost)  
Dim thLoopInsert As TaskHost = CType(forEachLoop.Executables.Add("STOCK:BulkInsertTask"), TaskHost)  
Dim loopExecs As Executables =  forEachLoop.Executables   
Console.WriteLine("Number of Executables in ForLoop: {0}", loopExecs.Count)  

' Like other containers, precedence constraints can be set on the  
' contained tasks.  
Dim pc As PrecedenceConstraint =  forEachLoop.PrecedenceConstraints.Add(CType(thLoopMail,thLoopInsert, Executable))   
Dim pcs As PrecedenceConstraints =  forEachLoop.PrecedenceConstraints   
Console.WriteLine("Number of precedence constraints: {0}", pcs.Count)  

Contoh Output:

Jumlah Executable di ForLoop: 2

Jumlah batasan prioritas: 1
