Task 构造函数

定义

初始化 Task 类的新实例。

protected:
 Task();
protected Task ();
Protected Sub New ()

示例

下面的代码示例使用构造函数创建一个新 BulkInsertTask 代码。

BulkInsertTask myTask = new BulkInsertTask();  
Dim myTask As BulkInsertTask =  New BulkInsertTask()  

注解

对于继承自 Task的任务,每个任务的“示例”部分中的代码示例演示如何调用任务构造函数。 但是,在大多数情况下,你将创建任务作为包的成员。 有关强制转换任务的详细信息,请参阅中的 Add备注。

Package pkg = new Package();  
Executable exec1 = pkg.Executables.Add("STOCK:BulkInsertTask");  
TaskHost th = exec1 as TaskHost;  
// You can cast the InnerObject of the TaskHost  
// to the specific class.  
// For the code samples, the task properties are accessed using  
// the Properties of the TaskHost.  
//BulkInsertTask myTask = th.InnerObject as BulkInsertTask;  
Dim pkg As Package =  New Package()   
Dim exec1 As Executable =  pkg.Executables.Add("STOCK:BulkInsertTask")   
Dim th As TaskHost =  exec1 as TaskHost   
' You can cast the InnerObject of the TaskHost  
' to the specific class.  
' For the code samples, the task properties are accessed using  
' the Properties of the TaskHost.  
'BulkInsertTask myTask = th.InnerObject as BulkInsertTask;  

可以使用变量th的属性和方法。BulkInsertTaskTaskHost
