使用gp工具追加数据

/// <summary>        /// 追加数据        /// </summary>        /// <param name="inputPath">源数据对象</param>        /// <param name="targetPath">目标数据对象</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情况下，追加后发现即使字段名相同也不能使属性值导入。通过比较ArcMap下Append工具的应用发现，选择NO_TEXT选项后，在Field_Mapping中自动出现对象关系。查找ArcEngine帮助文档发现此选项接收类型为IGPFiledMapping集合，集合为源对象字段与目标对象字段的对应关系，经分析如果字段名称一样的情况下，只要匹配源对象字段就可以解决属性值不能导入的问题。
解决属性字段不能导入问题
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类获取表集合IDETable，IDETable猜测为源对象表，没有经过严格测试，只是IDETable作为源对象表可以解决产生的问题。IGPFieldMapping类是对应关系集合。IGPFieldMap对应关系，需要匹配输入字段与输出字段，匹配后添加到IGPFieldMapping。
