It's good you got your code working !

I am going to respond with an example of using Linq that, imho, is valuable/educational because it illustrates using an index in a 'Select statement, dealing with the fact there is no equivalent to 'continue, or 'break, in a 'Select statement, and using 'GroupBy and 'ToDictionary to perform summation of the 'Value part of an 'IGroup:
string s = @"d1.8xlarge: 3 d1.xlarge: 0 c2.xlarge: 25
s1.medium: 1 c2.xlarge: 10 s1.large: 4 d1.8xlarge: 27";

string[] split = s.Split(new char[] {' ',':', '\r','\n'}, StringSplitOptions.RemoveEmptyEntries);

int limit = split.Length - 1;

var sorted = split.Select((string str, int ndx) => // declaration of auto-index
{
    int val;  // use of variable defined inside 'Select

    if (ndx < limit && int.TryParse(split[ndx + 1], out val))
    {
        return new {name = split[ndx], value = val};
    }
    else
    {
        return null; // you have to return something !
    }
})
.Where(itm => itm != null) // get rid of 'nulls
.GroupBy(itm => itm.name) // group on the 'name
.ToDictionary(grp => grp.Key, grp => grp.Sum(v => v.value)); // summation
I'm not claiming this is the best solution ! But, imho, the aspects of using Linq it demonstrates are very useful in many other situations.
