C# Split Function - Splitting String Delimited Files

I am having problems with the .split function.

token_list = line.Split(',');

My input data is a CSV file that contains numbers and strings totaling 5 columns. The strings are string delimited...

1, 2, "Test", 1, "Test" 5 columns
1, 2, "Test", 1, "Test" 5 columns
1, 2, "Test, Test", 1, "Test" 6 columns!!
1, 2, "Test", 1, "Test" 5 columns

The split function as it is written above is splitting the third line into 6 columns because there is a comma in the data. Is there a way for me to tell the split function to ignore commas in strings?
