What we want to do now is to store each team and the goals they scored. When we meet a team for the first time we add the name as a Key and the number of goals as the Item. If the team has already been added then we add the goals they scored in the current match to their total. If the teams exists in the Dictionary, the current goals are added to the current total for that team.

If the team does not exist in the Dictionary then it will automatically add the team to the Dictionary and set the value to the goals. We obviously want the scores to be sorted.

It is much easier to read this way. There is no easy way to sort a Dictionary. The way to do it is to copy all the items to an array. Sort the array and copy the items back to a Dictionary. What we can do is sort the data once it has been written to the worksheet. We can use the following code to do this:. Teams ordered by number of goals scored. We are going to use the data from the Multiple Values section above.
