问题描述
Thanks。
解决方案
您不需要使用 LINQ
,可以使用 FindIndex $ c
:
$ b $ pre $ code $> code>列表< T>
I am new to Linq. I have a Customers table.ID,FullName,Organization,Location being the columns. I have a query in Sqlite returning me 2500 records of customers. I have to find the index of the customer where ID=150 for example from this result set. Its a List of Customers. The result set of the query is ordered by organization. I tried with FindIndex and IndexOf but getting errors for the former and -1 for the latter. So, how should it be done? Thanks.
解决方案
You don't need to use LINQ
, you can use FindIndex
of List<T>
:
int index = customers.FindIndex(c => c.ID == 150);
