c# - Custom order by in sql query

Question

I am working a report which require custom order by statement. I have 5 categories which I am using for the order by clause. These are my column names student expenses, petty cash expenses, home expenses, daily expenses, Fair expenses. I want to order them in report in this manner:

Pettycash
DailyExpense
Home Expense
Fair Expense
Cash Expense

Also if new categories are added that wont effect this order and added in the last. I have tried order by asc and desc also searched some forums but it didnt cleared my concept. Thank you.
