Question

I’m just getting started with LINQ, and I’m having some troubles.

Say I wanted to do something like this:

IEnumerable<String[]> = from s in listOfStrings
                      where () => {
                          int sum = 0;
                          for (int i=0; i<s.Length(); i++)
                          {
                              sum += s[i];
                          }
                          return sum < 50;
                      }
                      select () =>
                      {
                          String[] t = new String[s.Length()];
                          for (int i=0; i<s.Length(); i++)
                          {
                              t[i] = s[i].toString();
                          }
                          return t;
                      }

Basically I want to get an array of characters as string values in from strings in listOfStrings that have a sum smaller than 50.

This is just an example though, It would be hard to think of a more useless function huh, I’m just trying to find out how to execute stuff in lambda functions within linq, without making a new function to do it.

Thanks!

If you use the method-chaining syntax instead of the query syntax (i.e. listOfStrings.Where(...)), you can stick the lambda in there.
