四、删除 Delete

文档目录

开始使用  初始化查询实例:

LambdaToSql.SqlClient DB = new LambdaToSql.SqlClient();

删除单个实体,通过Guid主键删除

var guid = Guid.Parse("5ed14b29-bf79-4a59-8ec4-9440f245dc10");
var entity = DB.QueryTable<EntityModel.System_UserInfo>(ex => ex.Guid == guid).FirstOrDefault();
var i = DB.DeleteTble<EntityModel.System_UserInfo>(entity).ExecuteNonQuery();

var i = DB.DeleteTble<EntityModel.System_UserInfo>(ex => ex.Guid == Guid.Parse("9c1d1247-cd2c-424d-be14-ef8abae655a4")).ExecuteNonQuery();

条件删除

var i = DB.DeleteTble<EntityModel.System_UserInfo>(ex => ex.PassWord == "").ExecuteNonQuery();

var item = new string[] { "", "", "", "", "" }.ToList();
var i1 = DB.DeleteTble<EntityModel.System_UserInfo>(ex => item.NotContains(ex.LoginName)).ExecuteNonQuery();
