Osservazioni

The ScriptTask class defines the Script task and handles the interaction of the Script task with the runtime and with Visual Studio for Applications.

Esempi

The following code sample, implemented in a console application, adds a ScriptTask to the package and displays the default values of some of its properties.

using System;
using Microsoft.SqlServer.Dts.Runtime;

namespace ScriptTaskCS
{
  class Program
  {
    static void Main(string[] args)
    {
      Package pkg = new Package();
      string newLine = System.Environment.NewLine;

      Executable exe = pkg.Executables.Add("STOCK:ScriptTask");
      TaskHost thTask = (TaskHost)exe;

      string taskInfo;
      taskInfo = 
        
        "Entry point: " + 
        thTask.Properties["EntryPoint"].GetValue(thTask) + newLine + 
        "Script Language: " + 
        thTask.Properties["ScriptLanguage"].GetValue(thTask) + newLine + 
        "ReadOnlyVariables: " + 
        thTask.Properties["ReadOnlyVariables"].GetValue(thTask) + newLine + 
        "ReadWriteVariables: " + 
        thTask.Properties["ReadWriteVariables"].GetValue(thTask);

      Console.WriteLine(taskInfo);
      Console.Read();
    }
  }
}

Imports Microsoft.SqlServer.Dts.Runtime

Module Module1

  Sub Main()

    Dim pkg As New Package
    Dim newLine As String = System.Environment.NewLine

    Dim exe As Executable = pkg.Executables.Add("STOCK:ScriptTask")
    Dim thTask As TaskHost = CType(exe, TaskHost)

    Dim taskInfo As String
    taskInfo = 
      
      "Entry point: " & _
      thTask.Properties("EntryPoint").GetValue(thTask) & newLine & _
      "Script Language: " & _
      thTask.Properties("ScriptLanguage").GetValue(thTask) & newLine & _
      "ReadOnlyVariables: " & _
      thTask.Properties("ReadOnlyVariables").GetValue(thTask) & newLine & _
      "ReadWriteVariables: " & _
      thTask.Properties("ReadWriteVariables").GetValue(thTask)

    Console.WriteLine(taskInfo)
    Console.Read()

  End Sub

End Module
