示例

在控制台应用程序中实现的以下代码示例将一个 ScriptTask 添加到包中，并显示其某些属性的默认值，包括 ReadOnlyVariables 该属性。

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
