扩展使用
ToEntity1st(查询数据,并将首条数据转换为数据实例)
// ToEntity1st(查询数据,并将首条数据转换为数据实例) using JCoder.Db4Net; using JCoder.Db4Net.ORM; IDbOperator _operator = new MsSqlFactoryOperator() { ConnectionString = "Server=127.0.0.1;Database=test;Uid = user; Pwd=testpassword;" }; return this.Operator.ToEntity1st<T>("select top 1 * from table1;");
ToEntities(查询数据,并转换为数据实体列表)
// ToEntities(查询数据,并转换为数据实体列表) using JCoder.Db4Net; using JCoder.Db4Net.ORM; IDbOperator _operator = new MsSqlFactoryOperator() { ConnectionString = "Server=127.0.0.1;Database=test;Uid = user; Pwd=testpassword;" }; return this.Operator.ToEntities<T>("select top 10 * from table1;");
CRUD(增删查改)
using JCoder.Db4Net; using JCoder.Db4Net.ORM; // Test Entity Class [DbTable("t_table_test")] public class TestEntity { [DbPrimaryKey] [DbAutoIncrement] public int Key001 { get; set; } [DbPrimaryKey] [DbField(IsUnique=true)] public string Key002 { get; set; } [DbIndex("idx01")] public string C003 { get; set; } } IDbOperator _operator = new MsSqlFactoryOperator() { ConnectionString = "Server=127.0.0.1;Database=test;Uid = user; Pwd=testpassword;" }; TestEntity x = new TestEntity() { Key001 = 101, Key002 = "Test PK", }; // Insert Data(新增数据) this.Operator.Insert<TestEntity>(x); // Update Data(更新数据) x.C003 = "Update Test"; this.Operator.Update<TestEntity>(x); // Delete Data(删除数据) this.Operator.Delete<TestEntity>(x); // Select Data(查询数据) this.Operator.Select1st<TEntity>(" and Key001=101 and Key002-'Test PK'");
Create\Drop Table From Entity(由实体类创建\删除数据库的数据表)
using JCoder.Db4Net; using JCoder.Db4Net.ORM; // Test Entity Class [DbTable("t_table_test")] public class TestEntity { [DbPrimaryKey] [DbAutoIncrement] public int Key001 { get; set; } [DbPrimaryKey] [DbField(IsUnique =true)] public string Key002 { get; set; } [DbIgnore] public string Key003 { get; set; } [DbIndex] [DbField(AllowNull = false, Default = "", Description = "Test Comment")] public string C001 { get; set; } [DbIndex("idx01")] public string C002 { get; set; } [DbIndex("idx01")] public string C003 { get; set; } [DbIgnore] public int C004 { get; set; } [DbField(AllowNull = false, Default = "0", Description = "Test Comment2")] public int C005 { get; set; } [DbNumberFieldExt(Precision = 11, Scale = 2)] public double C006 { get; set; } [DbField(AllowNull = false, Default = "", Description = "Test Comment2")] public string C007 { get; set; } public string C008 { get; set; } [DbTimeFieldExt(UpdateTimeOnCreate = true, UpdateTimeOnUpdate = true)] public DateTime C009 { get; set; } } IDbOperator _operator = new MsSqlFactoryOperator() { ConnectionString = "Server=127.0.0.1;Database=test;Uid = user; Pwd=testpassword;" }; this.Operator.CreateTable<TestEntity>(); this.Operator.DropTable<TestEntity>();
Orm工具类使用
转换首条数据为实体对象(支持DbDataReader、DataTable)
var _table = new DataTable(); // ToEntity1st JCoder.Db4Net.ORM.Orm.ToEntity1st<T>(_table); // ToObject1st JCoder.Db4Net.ORM.Orm.ToObject1st<T>(_table); JCoder.Db4Net.ORM.Orm.ToObject1st<T>(_table, OrmMappingMode.OnlyProperty); JCoder.Db4Net.ORM.Orm.ToObject1st<T>(_table, OrmMappingMode.OnlyDbAttribute); JCoder.Db4Net.ORM.Orm.ToObject1st<T>(_table, OrmMappingMode.DbAttributeFirst);
将数据转换为实体对象(支持DataRow、IDictionary<string, string>、IDictionary<string, object>))
var _dict = new Dictionary<string, string>(); // ToEntity JCoder.Db4Net.ORM.Orm.ToEntity<T>(_dict); // ToObject JCoder.Db4Net.ORM.Orm.ToObject<T>(_dict); JCoder.Db4Net.ORM.Orm.ToObject<T>(_dict, OrmMappingMode.OnlyProperty); JCoder.Db4Net.ORM.Orm.ToObject<T>(_dict, OrmMappingMode.OnlyDbAttribute); JCoder.Db4Net.ORM.Orm.ToObject<T>(_dict, OrmMappingMode.DbAttributeFirst);
将数据源转换为实体对象列表(支持DbDataReader、DataTable)
var _table = new DataTable(); // ToEntities JCoder.Db4Net.ORM.Orm.ToEntities<T>(_table); // ToObjects JCoder.Db4Net.ORM.Orm.ToObjects<T>(_table); JCoder.Db4Net.ORM.Orm.ToObjects<T>(_table, OrmMappingMode.OnlyProperty); JCoder.Db4Net.ORM.Orm.ToObjects<T>(_table, OrmMappingMode.OnlyDbAttribute); JCoder.Db4Net.ORM.Orm.ToObjects<T>(_table, OrmMappingMode.DbAttributeFirst);
将数据填充到已有的实体对象里(支持DbDataReader、DataRow、IDictionary<string, string>、IDictionary<string, object>)
var _source = new DbDataReader(); var _target = new T(); JCoder.Db4Net.ORM.Orm.FillToObject<T>(_target, OrmMappingMode.OnlyProperty, _source); JCoder.Db4Net.ORM.Orm.FillToObject<T>(_target, OrmMappingMode.OnlyDbAttribute, _source); JCoder.Db4Net.ORM.Orm.FillToObject<T>(_target, OrmMappingMode.DbAttributeFirst, _source);
将实体对象转换为DataTable
// 实体对象转换为DataTable DataTable _table = JCoder.Db4Net.ORM.Orm.EntityToDataTable(new T()); DataTable _table = JCoder.Db4Net.ORM.Orm.ObjectToDataTable(new T()); // 实体对象列表转换为DataTable DataTable _table = JCoder.Db4Net.ORM.Orm.EntitiesToDataTable(new List<T>()); DataTable _table = JCoder.Db4Net.ORM.Orm.ObjectsToDataTable(new List<T>());
将实体对象转换为Dictionary<string,string>
// 实体对象转换为Dictionary<string,string> Dictionary<string, string> _dict = JCoder.Db4Net.ORM.Orm.EntityToDict(new T()); Dictionary<string, string> _dict = JCoder.Db4Net.ORM.Orm.ObjectToDict(new T());
