I know that I can cast my linq query to an array or list but this doesn't seem to help.
Here is my query:
var bracct = from DataRow x in _checkMasterFileNew.Rows
select new {BranchAccount = string.Format("{0}{1}", x["Branch"], x["AccountNumber"])};
When I attempt to convert it to a list or array:
List<string> tstx = bracct.ToList();
or this:
string[] stx = bracct.ToArray();
If give me this:
I am assuming I need to change my query but I'm not sure the best way to hanlde it. How do I get it to a generic collection of strings?
It won't work because you've created an anonymous type with 1 property which is a string. Instead, If all you want is to convert it into a List<string>
do:
var bracct = (from DataRow x in _checkMasterFileNew.Rows
select string.Format("{0}{1}", x["Branch"], x["AccountNumber"])).ToList();
And if using c# 6.0 you can use string interpolation:
var bracct = (from DataRow x in _checkMasterFileNew.Rows
select $"{x["Branch"]}{x["AccountNumber"]}").ToList();
Your query is creating an anonymous type with a single member BranchAccount
. If you actually just want a string
, then just select that instead:
var bracct =
from DataRow x in _checkMasterFileNew.Rows
select string.Format("{0}{1}", x["Branch"], x["AccountNumber"]);
And now your ToList()
call will return List<string>
:
List<string> tstx = bracct.ToList();
You must select the property you are assigning the string to before performing ToList()
, or remove the anonymous type and select string.Format()
directly
Try this:
List<string> tstx = bracct.Select( x => x.BranchAccount ).ToList();
