Join 方法

Adds an existing container or task object to the Executables collection.

命名空间：  Microsoft.SqlServer.Dts.Runtime
程序集：  Microsoft.SqlServer.ManagedDTS（在 Microsoft.SqlServer.ManagedDTS.dll 中）

语法

声明
Public Sub Join ( _
    executable As Executable _
)
用法
Dim instance As Executables
Dim executable As Executable

instance.Join(executable)

public void Join(
    Executable executable
)

public:
void Join(
    Executable^ executable
)

member Join : 
        executable:Executable -> unit 

public function Join(
    executable : Executable
)

参数

• executable
  类型：Microsoft.SqlServer.Dts.Runtime. . :: . .Executable
  The name of the existing TaskHost for the container or task.

注释

Use Join when you move a container or task from one container (source) to another (destination). You must remove the object from the source container using Remove before calling Join on the destination.

示例

The following example creates a Bulk Insert Task and sets some properties. The Bulk Insert Task is then removed from the first package, and added to the second package. The properties set while it was part of the first package remain unchanged.

                      // Join the task from pkg to pkg2.
                      pkg2.Executables.Join(myTask);
                      // Show the number of executables in the second collection after Join.
                      Console.WriteLine("The second package now contains {0} executables", p2Execs.Count);
        }

Sample Output:

The first package now contains 0 executables

The second package initially contains 0 executables

The second package now contains 1 executables
