C# compare expected result with actual result

I'm writing a test which will generate an output for me from a linux file.

I've got code to read a linux file which will give me an ouput. For example the output will be 1,333,44,5. I want to compare this the expected result which i have stored in a excel file.

Is there code i can use which will help me compare the output from the linux file with the expected result which i have in my excel sheet. Comparing the two will allow me to see whether the test is passing or failing.
