C# 前台多个查询。In 参数化。分隔前台输入值

Posted 2021-01-08 邓振振 - HandLoong

  // 空白（空格、换行、tab）和逗号分隔的字符串，变成用逗号分隔
    function getSplitString(str) {
        var arr = str.split(",");
        var resources = "";
        for (var i = 0; i < arr.length; i++) {
            var arr1 = arr[i].split(/\s+/);

            for (var j = 0; j < arr1.length; j++) {
                if (jQuery.trim(arr1[j]) != "") {
                    resources += jQuery.trim(arr1[j]) + ",";
                }
            }
        }
        return resources;
    }

　　上面这个方法百度搜的,可以把类似  1  2 3 4   5,8 转换成 1,2,3,4,5,8

 

后台In拼接SQL参数化:

 

//串号
            if (!queryParam["IMEI"].IsEmpty())
            {
                hasWhere=strSql.AppendWhereOrAnd(hasWhere, @" 
 A.IMEI IN (");

                var arrImei = queryParam["IMEI"].ToString().TrimEnd(‘,‘);
                var imies = arrImei.Split(‘,‘);
                var strImeis = new StringBuilder();
                for (int i = 0; i < imies.Length; i++)
                {
                    strImeis.Append([email protected]"@imei_parm_justOne_{i},");
                    parameter.Add(DbParameters.CreateDbParameter([email protected]"@imei_parm_justOne_{i}", imies[i].Trim(), DbType.String));
                }
                strSql.Append(strImeis.ToString().TrimEnd(‘,‘));
                strSql.Append(") ");
            }
