public class DB {
public static readonly DbSession Context = new DbSession("DosConn");
}
var list = DB.Context.From<Dos.Model.TableName>().ToList();
四、使用示例html
全局配置: public class DB { public static readonly DbSession Context = new DbSession("DosConn"); } 查詢示例(Lambda表達式寫法): DB.Context.From<Dos.Model.TableName>() .Select(d => new { d.ID, d.Price }) //select ID,Price from TableName .Where(d => (d.ID == 2 && d.Name != "itdos" && d.Name.In("com","net","cn") && ) || d.Sex != null) // where (id=2 and Name<>'itdos' and Name in('com','net','cn')) or Sex is not null .GroupBy(d => new { d.Name, d.Sex }) //group by Name,Sex .OrderBy(d => new { d.CreateTime, d.Name }) //order by CreateTime,Name .Having(d => d.Name != '') //having Name<>'' .Top(5) .Page(10, 2) //分頁返回結果 每頁10條返回第2頁數據 .ToList(); //返回實體列表 //.ToFirst(); //返回第一個實體 //.ToFirstDefault(); //返回第一個實體,若是爲null,則默認實例化一個 //.ToDataSet(); //返回DataSet //.ToDataReader(); //返回IDataReader //.ToDataTable(); //返回DataTable //.ToScalar(); //返回單個值 插入示例: //單個實體插入 var newModel = new Dos.Model.TableName(){ ID = Guid.NewGuid(), Name = "ITdos.com" }; var count1 = DB.Context.Insert<Dos.Model.TableName>(newModel);
//批量插入 var newList = new List<Dos.Model.TableName>(); newList.Add(new Dos.Model.TableName(){ ID = Guid.NewGuid(), Name = "ITdos.com" }); var count2 = DB.Context.Insert<Dos.Model.TableName>(newList);
刪除示例: var count1 = DB.Context.Delete<Dos.Model.TableName>(d => d.ID == 1);
修改示例: var uptModel = DB.Context.From<Dos.Model.TableName>().Where(d => d.ID == 1).ToFirst(); uptModel.Attach(); uptModel.Name = "ITdos.net"; var count1 = DB.Context.Update<Dos.Model.TableName>(uptModel);
