4. arcengine拓扑：要素类复制实现

1. 方法实现

using ESRI.ArcGIS.Geoprocessor;
using ESRI.ArcGIS.Geoprocessing;
using ESRI.ArcGIS.DataManagementTools;
using ESRI.ArcGIS.AnalysisTools;
public static bool CopyFeatureClass(string inputPaths, string outputPath)
        {
            Geoprocessor gp = null;
            IGeoProcessorResult result = null;
            try
            {
                Copy pCopy = new Copy(inputPaths, outputPath);
                gp = new Geoprocessor();
                gp.OverwriteOutput = true;
                gp.TemporaryMapLayers = false;
                result = (IGeoProcessorResult)gp.Execute(pCopy, null);
                if (result != null)
                    return true;
                else
                    return false;
               
            }
            catch
            {
                string str = ReturnMessages(gp);
                return false;
            }
            finally
            {
                if (gp != null)
                {

                    gp = null;

                }
                GC.Collect();
                GC.WaitForFullGCComplete();
            }
        }

        /// <summary>
        /// 处理错误信息
        /// </summary>
        /// <param name="gp"></param>
        /// <returns></returns>
        private static string ReturnMessages(Geoprocessor gp)
        {
            string ms = "";
            if (gp.MessageCount > 0)
            {
                for (int Count = 0; Count <= gp.MessageCount - 1; Count++)
                {
                    ms += "$" + gp.GetMessage(Count) + "\n\n";
                }
            }

            if (ms.Contains("Succeeded") || ms.Contains("成功"))
            {
                //MarkConfig(true);
                return "";
            }
            return ms;
        }

2. 使用方式

CopyFeatureClass(strpath + "\\" + GT_COMMONNOUN.NJQ + "_" + strMC + "_" + strDM, strpath + "\\" + GT_COMMONNOUN.hz_njq);
