I have sentence having csv values from table like 'PROVIDENT FUND,Employee Contribution to PF,PF,Employee PF ' .Now I want to match exact word '

HTML

Employee Contribution to PF

' exist in this sentence or not without splitting and mapping each values .Because this sentence may increases .And with Splitting and mapping may decrease performance .So how to match exact word in simple way ?

What I have tried:

I get string values in loop after splitting then I mapped.For this I made two for loops in which outer loop gets every row csv values rows and then loop on csv field after splitting.Now i want proper solution for this without for loop as performance decreases as values increases in both inner and outer loop values.
How to resolve this?Thanks in advance ......

To be honest, I'd use an existing CSV reader: A Fast CSV Reader[^] is good.
You can then just use string.Contains to find your matches.

Do you write this because you know another way that perform better ? if so, program it.

- Simple minded method: Take the sentence and search a given word using standard function. Search "fund" in "I have made a crowdfunding.", you will have a match, but is it what you want ? You need to check for spaces before and after the word unless it is the first or last one. Is it still the easy way.

- split method: you split the sentence in words only once. Each list entry is a word, you just have to check if a list entry is equal to a word or not, no special cases.

Use the split method. when you think of a better method, try it and compare the performance results. and tell us.
