Splitting a string with VB.Net?

[Sheena777]

I am getting a string from a user and Would like to split the Data base on certain cinditions, I know how to split the sting with an Array and the Split method. I am fine if the user has put that string in correctly but if they use a different delimeter then the code does not pick that up just ignores any splitting and goes on with the program and the whole string instead of what I wanted.How can I force the Program to break if the string can't be split so that i can get and error message for this. My code is already in a try catch block and even when I do try to force the break the code seems to side step somthing. Any Help will be Appreciated thank

Well the .Split() method returns an array.
Simply look at the size of the array, if there are not X pieces (where X is the amount you need to be 'correctly split') then throw a new exception to trigger your try/catch blocks.
Or do a check with .IndexOf() or .Contains() to see if your delimeter is even in the string in the first place?
