ArcEngine常用代码

（不断更新中……）

1.获取要素所在的图层

pFeature.Class.AliasName.ToString()

2.GP中批量处理数据

            GP.SetEnvironmentValue("workspace", gdbPath);            IGpEnumList listFeatureClass = GP.ListFeatureClasses("", "", "");            string featureClass = listFeatureClass.Next();            while (featureClass != "" )             {                if (featureClass != "road" && featureClass != "boundary")                {                    Delete del = new Delete();                    del.in_data = gdbPath + featureClass;                    RunGPTool(GP, del, null);                }                featureClass = listFeatureClass.Next();            }
