参数
- taskHost
类型：Microsoft.SqlServer.Dts.Runtime.TaskHost
A nullnull 引用（在 Visual Basic 中为 Nothing） value.
- progressDescription
类型：System.String
A string that describes the progress event that is raised.
- percentComplete
类型：System.Int32
An integer used to indicate how much of the task has completed.
- progressCountLow
类型：System.Int32
An integer that contains the low 32-bits of the units completed.
- progressCountHigh
类型：System.Int32
An integer that contains the high 32-bits of the units completed.
- subComponent
类型：System.String

注释
Called any time a task experiences measurable progress. Each task has its own requirements, but as a general rule, a task reports progress in increments of 1 percent. OnProgress is called by the task at predetermined intervals to update listening clients about the progress of a particular task.
