字典c＃上的算术运算

Question

我将此词典对象设为： - Dictionary<string,string> lstTransList;

此对象的值为|Key={Id}|Value={|QTY=4|PICKEDUP=2}|

现在我想计算记录的数量，QTY和＆amp;的差异。每个记录的PICKEDUP，然后是QTY的总和，总和PICKEDUP＆amp;差异总和。 有没有使用LINQ执行这些算术运算的有效方法？

我算作： - int total_transactiondone = lstTransList.Count();

对于QTY的求和我想用键分割字典对象的值为＆＃39; QTY＆＃39; ＆安培; ＆＃39;拾取＆＃39;但不知道如何使用它。有什么建议??

考虑使用这样的东西：

decimal total_tickets = lstTransList.Sum(x => Convert.ToDecimal(x.Value));

修改：

现在我使用followin方法来完成这项任务。有没有其他有效的方法来做到这一点？请建议。

var lstTransList = objRedis.GetAllEntriesFromHash(strHashey);

DataTable dtTransList = new DataTable();
dtTransList.Columns.Add("TransId");
dtTransList.Columns.Add("Qty", typeof(int));
dtTransList.Columns.Add("PickedUp", typeof(int));
dtTransList.Columns.Add("UnPickedUp", typeof(int));

foreach (KeyValuePair<string, string> entry in lstTransList)
{
    DataRow DR = dtTransList.NewRow();
    if (!string.IsNullOrEmpty(entry.Key))
    {
        DR[0] = entry.Key;
    }
    if (!string.IsNullOrEmpty(entry.Value))
    {
        clsKeyValueParser objKV = new clsKeyValueParser(entry.Value);
        DR[1] = Convert.ToInt32(objKV.strGetValue("QTY", "0"));
        DR[2] = Convert.ToInt32(objKV.strGetValue("PICKEDUP", "0"));
        DR[3] = Convert.ToInt32(DR[1]) - Convert.ToInt32(DR[2]);
    }
    dtTransList.Rows.Add(DR);
}


int total_transactiondone = dtTransList.Rows.Count;
int total_tickets = dtTransList.AsEnumerable().Sum(x => x.Field<int>(1));
int total_ticketsunpickedup = dtTransList.AsEnumerable().Sum(x => x.Field<int>(3));
int total_pickeduptransaction = dtTransList.AsEnumerable().Count(row => row.Field<int>(3) == 0);
int total_unpickeduptransaction = dtTransList.AsEnumerable().Count(row => row.Field<int>(3) != 0);

Answer 1

尝试此操作以获得总数QTY

decimal total_tickets_qty = lstTransList.Sum(x => Convert.ToDecimal(Regex.Match(x.Value.Split('|')[1], @"\d+").Value);

PICKEDUP总计

decimal total_tickets_pickedup = lstTransList.Sum(x => Convert.ToDecimal(Regex.Match(x.Value.Split('|')[2], @"\d+").Value));

差异总和

decimal total_tickets = lstTransList.Sum(x => Convert.ToDecimal(Regex.Match(x.Value.Split('|')[1], @"\d+").Value) - Convert.ToDecimal(Regex.Match(x.Value.Split('|')[2], @"\d+").Value));
