[英]Array comparison and sorting to list c#
I have data table with column "Subject", row 1 [subject] column in data table "ABC / Vesse / 11371503 /C report " row 2 [subject] column in data table "Value/BEY/11371503/A report" I need to compare the values inside subject column based on / and if the value before / is same,i should look for next value before next slash and sort..我有包含“主题”列的数据表,数据表“ABC / Vesse / 11371503 / C 报告”中的第 1 [主题] 列数据表“值/BEY/11371503/A 报告”中的第 2 行 [主题] 列我需要比较基于 / 的主题列内的值,如果 / 之前的值相同,我应该在下一个斜杠之前查找下一个值并排序..
As suggested, I'm splitting based on /
strSubSplit.正如建议的那样,我基于
/
strSubSplit 进行拆分。 Can please help how to sort and add to the list after comparing.可以请帮助如何排序和比较后添加到列表中。 Thanks a lot.
非常感谢。
if (ds.Tables[0].Rows.Count > 0)
{
foreach (DataRow row in ds.Tables[0].Rows)
{
string strSubject = row["Subject"].ToString();
string strEmailFrom = row["EmailFrom"].ToString();
string strEmailTo = row["EmailTo"].ToString();
string strEmailCC = row["EmailCc"].ToString();
string strEmailContent = row["EmailContent"].ToString();
// Do proper error handling here
DateTime strCreatedOn = DateTime.Parse(row["CreatedOn"].ToString());
string[] strSubSplit= row["Subject"].ToString().Split(new[] {'/'},StringSplitOptions.RemoveEmptyEntries);
mailInfoList.Add(new Tuple<string, string, string, string, string, DateTime>(strSubject, strEmailFrom, strEmailTo, strEmailCC, strEmailContent, strCreatedOn));
var newList = mailInfoList.OrderBy(x => x.Item1).ThenBy(x => x.Item6).ToList();
}
}
First Row contains ABC / Vesse / 11371503 /C report
and Second contains Value /BEY /11371503 /A report
第一行包含
ABC / Vesse / 11371503 /C report
,第二行包含Value /BEY /11371503 /A report
Try,尝试,
string strSubject = string.Join("/",row["Subject"]
.ToString()
.Split(new[] { '/' },
StringSplitOptions.RemoveEmptyEntries
).ToList().OrderBy(x => x));
now updated values are contains现在更新的值包含
Row 1 11371503 /ABC /C report/Vesse
Row 2 11371503 /A report/BEY /Value
Row 1
11371503 /ABC /C report/Vesse
Row 2 11371503 /A report/BEY /Value
and in your newList variables sorted again based on the subject,并在您的 newList 变量中根据主题再次排序,
var newList = mailInfoList.OrderBy(x => x.Item1).ThenBy(x => x.Item6).ToList();
Which give your final result becomes这给你的最终结果变成
Row 1 11371503 /A report/BEY /Value
Row 2 11371503 /ABC /C report/Vesse
Row 1
11371503 /A report/BEY /Value
Row 2 11371503 /ABC /C report/Vesse
Try this:尝试这个:
// assuming you'll already have the subjects of the emails
var subjects = new List<string>
{
"ABC / Vesse / 11371503 /C report",
"Value/BEY/11371503/A report"
};
var listOfItems = new List<Tuple<string, string, int, string>>();
subjects.ForEach(s =>
{
var splits = s.Split(new[] {'/'}, StringSplitOptions.RemoveEmptyEntries).Select(x => x.Trim()).ToArray();
// Do proper error checking before the int.Parse and make sure every array has 4 elements
listOfItems.Add(
new Tuple<string, string, int, string>(splits[0],
splits[1],
int.Parse(splits[2]),
splits[3]));
});
var newList = listOfItems
.OrderBy(x => x.Item3) // the number
.ThenBy(x => x.Item4) // {x} report
.ToList();
