如何从 linq 查询结果中拆分变量

Question

I want to split the data result from linq query , let's say from this code where I write

            string[] items;
            var data = from c in db.CMRTables where c.Id.Equals(17776) select new {  c.Auth, c.amount };
            string s = String.Join(",", data);
            items = s.Split(',');
            MessageBox.Show(items[0]);

It will return { Auth = 80231252 , amount = 8888888 } , I want to split the value so I can store it to variable ,

My expected result is 80231252 and 8888888 only , when I split it , how to do it? and what I select is basically not 2 values , but more than 2 values or I can say like 19 values

Answer 1

Why cant you just,

var data = (from c in db.CMRTables where c.Id.Equals(17776) select new { c.Auth, c.amount }).FirstOrDefault();
var ExpectedResult = data.Auth + "," + data.amount;

Split on ',', then use enumerator to process each entry:

string[] items = s.Split(',')
                  .Select(keyVal => keyVal.Split('=')[1].Trim())
                  .ToArray();

This above:

• splits string s using separator ',' into temporary array ( Split() )

• for each item in this temporary array gets this item as keyVal string and process those using formula on right side of '=>' ( Select() )

• converts the result to string[] array.

You could use Regex for the purpose.

var numbers = Regex.Matches(str, @"\d+")
                   .Cast<Match>()
                   .Select(x=>x.Value);

If you want the result as List<Long>

var numbers = Regex.Matches(str, @"\d+")
                   .Cast<Match>()
                   .Select(x=>long.Parse(x.Value));
