使用gp工具追加數據

/// <summary>        /// 追加數據        /// </summary>        /// <param name="inputPath">源數據對象</param>        /// <param name="targetPath">目標數據對象</param>        public static void GPAppend(AppendFeature inputPath, IFeatureClass targetPath)        {            GeoPRocessor mGeoprocessor = new Geoprocessor();            mGeoprocessor.OverwriteOutput = true;            Append mAppend = new Append();            mAppend.inputs = inputPath.FeatureClass;            mAppend.target = targetPath;            mAppend.schema_type = "NO_TEST";            //mAppend.field_mapping = GetFieldMapping(inputPath.FileFullPath);            string mMessageGP = "";            mGeoprocessor.Execute(mAppend, null);            for (int pMessageCount = 0; pMessageCount < mGeoprocessor.MessageCount; pMessageCount++)            {                mMessageGP += mGeoprocessor.GetMessage(pMessageCount);            }        }    schema_type 在NO_Text情況下，追加后發現即使字段名相同也不能使屬性值導入。通過比較ArcMap下Append工具的應用發現，選擇NO_TEXT選項后，在Field_Mapping中自動出現對象關系。查找ArcEngine幫助文檔發現此選項接收類型為IGPFiledMapping集合，集合為源對象字段與目標對象字段的對應關系，經分析如果字段名稱一樣的情況下，只要匹配源對象字段就可以解決屬性值不能導入的問題。
解決屬性字段不能導入問題
public static IGPFieldMapping GetFieldMapping(string ExInputPath)        {            IGPUtilities mGPUtilities = new GPUtilitiesClass();            IDETable mDETable = (IDETable)mGPUtilities.MakeDataElement(ExInputPath, null, null);            IArray mArray = new ArrayClass();            mArray.Add(mDETable);            IGPFieldMapping mGPFieldMapping = new GPFieldMappingClass();            mGPFieldMapping.Initialize(mArray, null);            //create new fieldmap            IGPFieldMap mGPFieldMap = new GPFieldMapClass();            //mGPFieldMap.OutputField = mFC1.Fields.get_Field(1);            //match field            int fieldmap_index = mGPFieldMapping.FindFieldMap("BSM");            IGPFieldMap mGPFNew = mGPFieldMapping.GetFieldMap(fieldmap_index);            int field_index = mGPFNew.FindInputField(mDETable, "BSM");            IField mField = mGPFNew.GetField(field_index);            mGPFieldMap.AddInputField(mDETable, mField, -1, -1);            mGPFieldMapping.AddFieldMap(mGPFieldMap);            return mGPFieldMapping;        }    其中GPUtilities類獲取表集合IDETable，IDETable猜測為源對象表，沒有經過嚴格測試，只是IDETable作為源對象表可以解決產生的問題。IGPFieldMapping類是對應關系集合。IGPFieldMap對應關系，需要匹配輸入字段與輸出字段，匹配后添加到IGPFieldMapping。
