如何在 dapper 扩展中使用 DESC 顺序根据 Order by 子句对数据进行排序?
How to Sort data according to Order by clause using DESC order in dapper extensions?
我想按降序排列数据。这是我的代码:
var predicate = Predicates.Sort<myPoco>(x => x.name, false);
var result = GetList<myPoco>(predicate).ToList();
protected IEnumerable<T> GetList<T>(object predicate, IList<ISort> sort = null, IDbTransaction transaction = null, int? commandTimeout = null, bool buffered = false) where T : class
{
var result = connection.GetList<T>(predicate, sort, transaction, commandTimeout, buffered);
return
}
使用 Dapper Extensions,我无法对数据进行排序。上面的代码抛出以下错误:
PropertyName was not found for...
我正在使用 Dapper Extension 的 ClassMapper
映射 myPoco
属性。
您可以在 Dapper Extension 中使用 ISort
对数据进行排序。
List<ISort> sortList = new List<ISort>();
sortList.Add(Predicates.Sort<myPoco>(x => x.Name, false));
var result = GetList<myPoco>(null, sortList).ToList();
return result;
protected IEnumerable<T> GetList<T>(object predicate, IList<ISort> sort = null, IDbTransaction transaction = null, int? commandTimeout = null, bool buffered = false) where T : class
{
var result = connection.GetList<T>(predicate, sort, transaction, commandTimeout, buffered);
return result;
}
