ArcEngine调用GP里的Merge工具传参问题

Merge工具inputs参数形式与Python中不同：

string startLayerPath= cpj.TempWs.PathName + @"" + datasetName + @"" + currentFc.Key + "start";

string endLayerPath= cpj.TempWs.PathName + @"" + datasetName + @"" + currentFc.Key + "end";

Merge mergeTool = new Merge();
mergeTool.inputs = """+startLayerPath+";"+endLayerPath+""";
