A user-defined object.
Замечания
The ExecutionValue property of the task is a read-only object property that enables the task to expose information regarding the results of its execution, post messages, or return the DTSExecResult return value. For example, if a task deletes rows from a table as part of its Execute method, it might return the number of rows deleted as the ExecutionValue. Clients of the task could then use this value to establish precedence constraints between tasks.
Tasks override the base implementation of the ExecutionValue property, and override the value that is set by the task during its Execute method.
Примеры
The following code example creates an FtpTask, then shows the default values it contains after creation. Some fields are empty, and must be explicitly set before the task is executed in the package.

Executable exec1 = pkg.Executables.Add("STOCK:FTPTask");
TaskHost th = exec1 as TaskHost;
// List the default values of the FTP task
// using the Properties collection of the TaskHost.
Console.WriteLine("Connection {0}", th.Properties["Connection"].GetValue(th));
