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);

                     }
