c# - Escaped patten causes compile error -

i have regex pattern:

r = new regex("^((\"(?:[^\"]|\"\")*\"|[^,]*)(,(\"(?:[^\"]|\"\")*\"|[^,]*))*)$"); 

this causing error: "cs1002: ; expected"

i can't see causing this.

if supposed c# have use lowercase new:

r = new regex("^((\"(?:[^\"]|\"\")*\"|[^,]*)(,(\"(?:[^\"]|\"\")*\"|[^,]*))*)$");
