//生成简单查询脚本
var sqlProvider = SqlProvider.CreateProvider();

////ado.net 使用例子
string connectionString = ConfigurationManager.ConnectionStrings["DbConnection"].ConnectionString;
AdoProvider dbProvider = AdoProvider.CreateProvider(connectionString, ProviderType.SqlServer);
var adort = dbProvider.Query(new DbExecuteParameter()
{
CommandText = "select * from [user]"
});
DataTable dt = new DataTable();
var qrt = dbProvider.QueryToTable(new DbExecuteParameter("select * from [user]"), dt);
//entity framework 使用例子
IOrmProvider ormProvider = OrmProvider.CreateProvider("DbConnection");
try
{
User item = ormProvider.GetById <User>(1);
UserDto ud = new UserDto()
{
UserName = "******"
};
var query = ormProvider.Query <User>().FirstOrDefault();
//使用mapper修改对象
EntityMapper.MapTo <UserDto, User>(ud, item);
ormProvider.Update(item);
//保存修改
int rt = ormProvider.SaveChanges();
}
catch (Exception ex)
{
Console.Write(ex.Message);
