创建featureclass，为它赋别名，并移动到数据集下

 if (pOutFtrClass == null)

                     {

                         //continue;

 //创建featureclass

                         //得到规范的字段集

                         IFields pFields = pFeatureClass.Fields;

                         //在目标工作空间中创建要素类

                         IFieldChecker fieldChecker = new FieldCheckerClass();

                         IEnumFieldError enumFieldError = null;

                         IFields validatedFields = null;

                         fieldChecker.ValidateWorkspace = pDataset.Workspace;

                         fieldChecker.Validate(pFields, out enumFieldError, out validatedFields);

 pOutFtrClass = (pDataset.Workspace as IFeatureWorkspace).CreateFeatureClass((pFeatureClass as IDataset).Name, validatedFields, null, null, esriFeatureType.esriFTSimple, "SHAPE", "");

 //为此featureclass赋别名

                         IClassSchemaEdit classedit = pOutFtrClass as IClassSchemaEdit;

                         string aliasName = pFeatureClass.AliasName;

                         if (!string.IsNullOrEmpty(aliasName))

                         {

                                //如果是表格要加上这句，添加一个oid
　　　　　　　　　　　　　　　　　　　　//classedit.RegisterAsObjectClass("OBJECTID", null);
　　　　　　　　　　　　　　　　　　　　classedit.AlterAliasName(aliasName);

                         }

 //把此featureclass移动到目标数据集下

                         (pDataset as IDatasetContainer).AddDataset(pOutFtrClass as IDataset);

                     }
