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);

                    }
