net下的半自动orm+linq的《SqlBatis》

 //for xml query
 var resovle = new XmlResovle();
 resovle.Load(@"E:\SqlBatis\SqlBatis.Test", "*.xml");
 //普通sql
 var sql1 = resovle.Resolve("namespace.id");
 //动态sql
 var sql2 = resovle.Resolve("namespace.id",new { Id=(int?)null,Age=2});
            

 四、配置DbContext

  方式1

public class MysqlDbConrext : DbContext
{
    public IDbQuery<Student> Students { get => new DbQuery<Student>(this); }
    private static readonly IXmlResovle resovle;
    static MysqlDbConrext()
    {
        //不要为每一个DbContext加载配置
        resovle = new XmlResovle();
        resovle.Load(@"E:\SqlBatis\SqlBatis.Test","*.xml");
    }
    protected override void OnLogging(string message, object parameter = null, int? commandTimeout = null, CommandType? commandType = null)
    {

    }
    protected override DbContextBuilder OnConfiguring(DbContextBuilder builder)
    {
        ILoggerFactory factory = LoggerFactory.Create(b => { b.AddConsole(); b.AddDebug(); b.SetMinimumLevel(LogLevel.Debug); });
        builder.Connection = new MySql.Data.MySqlClient.MySqlConnection("server=127.0.0.1;user id=root;password=1024;database=test;");
        builder.XmlResovle = null;
        return builder;
    }
    public MysqlDbConrext()
    {
        Students = new DbQuery<Student>(this);
    }
}

 方式2

var db = new DbContext(new DbContextBuilder()
{ 
    DbContextType=DbContextType.Mysql,
    ...
});

五、XML+Linq

using (var db = new SqlDbContext())
{
    //linq
    var row = db.Students.Delete();
    var (list, count) = db.Students
        .Page(1, 2)
        .SelectMany();
    //dynamic
    var p = new { Id = (int?)null, Name = "zs" };
    var dylist = db.Students
       .Where(a => a.Id == 1, p.Id != null)
       .Where(a => a.Name == p.Name, p.Name != null)
       .SelectMany();
    //xml
    row = db.From("sutdent.add", new Student()
    {
        Age = 20,
        IsDelete = true,
        Name = "xml"
    }).ExecuteNonQuery();
    //dynamic：注意由于内部会缓存表达式创建的委托，因此同一个动态的xml命令不能用不同的参数去获取它
    //建议如果获取的xml命令是动态的，则应保证整个项目只有一次获取的代码，或者使用同一种参数类型
    row = db.From("stutdent.list-dynamic", p).ExecuteNonQuery();
    //多结果集查询，xml方式同样支持
    using (var muti = db.ExecuteMultiQuery("select * from student;select count(1) from student;"))
    {
        //第一个结果集
        var list = muti.GetList<Student>();
        //第二个结果集
        var count = muti.Get<int>();
    }
}
