	名稱	說明
	ScriptTask	Initializes a new instance of the ScriptTask class.

屬性

	名稱	說明
	BreakpointManager	Returns the BreakpointManager used for controlling breakpoints on this task.
	Breakpoints	Returns an array of breakpoints set on this task.
	DebugMode	Gets or sets a value indicating whether the task is running in debug mode, and whether it should raise the OnBreakpointHit event while the task is running.
	EntryPoint	Gets or sets the name of the class that is executed as the entry point.
	ExecutionValue	Returns a user-defined object. This field is read-only. (覆寫 Task. . :: . .ExecutionValue。)
	ReadOnlyVariables	Gets or sets the comma-delimited list of existing variables made available to the package by the user for read-only access.
	ReadWriteVariables	Gets or sets the comma-delimited list of existing variables made available to the package by the user for read/write access.
	ScriptingEngine	Gets the VSTATaskScriptingEngine class.
	ScriptLanguage	Gets or sets the programming language in which the script is written.
	ScriptLoaded	Gets a value indicating whether the task contains custom script.
	ScriptProjectName	Gets or sets the name of the script project.
	ScriptStorage	Gets the [VSTAScriptProjectStorage].
	SuspendRequired	Gets or sets a Boolean indicating whether a task should suspend execution when the task encounters a breakpoint. This value is set by the run-time engine for tasks and containers when a breakpoint is encountered.
	Version	* Member deprecated; see Remarks. * Returns the version of the task. This property is read-only. (繼承自 Task。)

	名稱	說明
	AcceptBreakpointManager	Passes a BreakpointManager to the task. This method is called by the runtime and is not used in code.
	CanUpdate	* Member deprecated; see Remarks. * A Boolean that indicates whether the new package XML can update the old package XML. (繼承自 Task。)
	Equals	Determines whether two object instances are equal. (繼承自 DtsObject。)
	Execute	Runs the Script task. (覆寫 Task. . :: . .Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object)。)
	Finalize	Releases all resources used by the ScriptTask. (覆寫 Object. . :: . .Finalize() () () ()。)
	GetConnectionID	Gets a String containing the ID of the connection. (繼承自 Task。)
	GetConnectionName	Gets a String containing the name of the connection. (繼承自 Task。)
	GetHashCode	Returns the hash code for this instance. (繼承自 DtsObject。)
	GetType	(繼承自 Object。)
	InitializeTask	Initializes the properties associated with the Script task. This method is called by the runtime and is not used in code. (覆寫 Task. . :: . .InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker)。)
	LoadFromXML	Loads the Script task data from XML. This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
	MemberwiseClone	(繼承自 Object。)
	ReportBreakpointChanges	基礎結構。
	ResumeExecution	Resumes execution of the task or container by the run-time engine after pausing.
	SaveToXML	Saves the Script task component to XML. This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
	SetUniqueScriptProjectName	Sets the unique name of the script project.
	SuspendExecution	Indicates that the executable must suspend execution. This method is called by the run-time engine.
	ToString	(繼承自 Object。)
	Update	* Member deprecated; see Remarks. * This method updates the old package XML with the new package XML if CanUpdate is set to true. (繼承自 Task。)
	Validate	Verifies that the component is correctly configured. (覆寫 Task. . :: . .Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging)。)

備註

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

範例

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
