代码说明：

  ArcEngine中的ILegend和ILegendItem使用起来总觉得不让人满意，特别是AdjustColumns和Item。因此把PageLayout的图例想象成很多Element的组合，基于IElement重新实现了图例类。图例类的类图可以参考附件中的图例绘制.bmp。 另外，附件中有示例程序，示例mxd，还有源码。(ArcEngine in ILegend and ILegendItem people to use do not always feel satisfied, especially AdjustColumns and Item. So imagine the legend PageLayout lot Element combination, to re-implement a legend based on IElement class. Legend class class diagram can refer to the attached drawing legend. Bmp. In addition, in the annex to the sample program, sample mxd, there is source code.)
