How to split a string on the nth occurrence?

What I want to do is to split on the nth occurrence of a string (in this case it's "\t"). This is the code I'm currently using and it splits on every occurrence of "\t".

string[] items = input.Split(new char[] {'\t'}, StringSplitOptions.RemoveEmptyEntries);

If input = "one\ttwo\tthree\tfour", my code returns the array of:

• one
• two
• three
• four

But let's say I want to split it on every "\t" after the second "\t". So, it should return:

• one two
• three
• four
