Question

I want to convert this LINQ code

var x = from nm in names 
        select MyClass.SomeMethod(nm).TrimStart(',');
foreach (var vv in x)
{
    // I want to group and count different types of vv here
}

to use shorter syntax, one where they do x => x in LINQ. I also want to group and count ‘vv’ (there could be number of similar vv’s)

Answer 1

Well, the “dot notation” or “fluent notation” for the above is:

var x = names.Select(nm => MyClass.SomeMethod(nm).TrimStart(','));

For grouping:

var x = names.Select(nm => MyClass.SomeMethod(nm).TrimStart(','));
             .GroupBy(vv => vv, 
                      (key, group) => new { Key = key, Count = group.Count() });
