使用Dapper参数化查询（二）

查询封装

/// <summary>
    /// 分页查询条件
    /// </summary>
    public class PageWhere
    {
        /// <summary>
        /// 
        /// </summary>
        public QueryWhere queryWhere { get; set; }
        /// <summary>
        /// 每页显示数量
        /// </summary>
        public int pageSize { get; set; }
        /// <summary>
        /// 第几页
        /// </summary>
        public int pageIndex { get; set; }
        /// <summary>
        /// 排序字段
        /// </summary>
        public string filedOrder { get; set; }
    }

    /// <summary>
    /// 查询条件
    /// </summary>
    public class QueryWhere
    {
        public QueryWhere()
        {
            listWhere = new List<string>();
            dicWhere = new List<DicWhere>();
        }
        /// <summary>
        /// 查询条件
        /// </summary>
        public List<string> listWhere { get; set; }
        /// <summary>
        /// 赋值
        /// </summary>
        public List<DicWhere> dicWhere { get; set; }
    }

    /// <summary>
    /// 字段==值
    /// </summary>
    public class DicWhere
    {
        /// <summary>
        /// 字段
        /// </summary>
        public string filed { get; set; }
        /// <summary>
        /// 对应值
        /// </summary>
        public object value { get; set; }
    }

转换为dapper的dy

QueryParameter qp = new QueryParameter();
qp.listWhere = pageWhere.queryWhere.listWhere;
pageWhere.queryWhere.dicWhere.ForEach(item =>
{
   qp.dynamicParameter.Add(item.filed, item.value);
});
return _prerecordBLL.GetList(qp, pageWhere.pageSize, pageWhere.pageIndex, pageWhere.filedOrder);

调用

if (!string.IsNullOrWhiteSpace(gltxtcinput.Text))
{
   qw.listWhere.Add(" a.cinput=@cinput ");
   qw.dicWhere.Add(new DicWhere() { filed = "@cinput", value = gltxtcinput.EditValue });
}
