I cannot believe I am having trouble with this following string

String filter = "name=Default;pattern=%%;start=Last;end=Now";

This is a short and possibly duplicate question, but how would I split this string to get:

string Name = "Default";
string Pattern = "%%" ;
string start = "Last" ;
string end = "Now" ;

Reason why I ask is my deadline is very soon, and this is literally the last thing I must do. I'm Panicking, and I'm stuck on this basic command. I tried:

pattern = filter.Split(new string[] { "pattern=", ";" },
                       StringSplitOptions.RemoveEmptyEntries)[1]; //Gets the pattern
startDate = filter.Split(new string[] { "start=", ";" },
                         StringSplitOptions.RemoveEmptyEntries)[1]; //Gets the start date

I happen to get the pattern which I needed, but as soon as I try to split start, I get the value as "Pattern=%%"

What can I do?

Forgot to mention The list in this string which needs splitting may not be in any particular order . this is a single sample of a string which will be read out of a stringCollection (reading these filters from Properties.Settings.Filters
