- [Instructor] The last collection type…I want to show you in C# is a dictionary.…So far we have seen the use of lists…and arrays and in those cases,…we were able to create, for example,…a list and this case we'll make a new list of strings.…We would add things to that.…
I'll say C# is awesome, and then…we would get that value back based…on its position, so in this case…it would test list zero, because…it's the first thing in the list,…but what if you could do this without…dealing with the numerical index?…Wouldn't it be cooler if you had…some way of making a list that allowed…you to use a key value pair situation…so you could, instead of a number,…assign some meaningful string here?…That is effectively what a dictionary is.…
An example of a dictionary might look like this.…To really drive the point home,…I think I'll actually create something…that looks exactly like a dictionary.…Why don't I create a variable called dictionaryWords…and I'll set it equal to a new dictionary.…We can see our diamond there, just like…
