How to validate a .csv file before storage in C#?

Question

I have some .csv files which I am parsing before storing in database.

I would like to make application more robust, and perform validation upon the .csv files before

Thank you for your response to my question.

I solved my problem by writing a solution to validate my .csv file myself.

It's quite possible a more elegant solution could be made by making use of adrianm's code, but I didn't do that, but I am encouraging to give adrianm's code a look.

I am validating the list below.

• Empty file new FileInfo(dto.AbsoluteFileName).Length == 0

• Wrong formatting of file lines. string[] items = line.Split('\t'); if (items.Count() == 20)

• Wrong datatype in line fields. int number; bool isNumber = int.TryParse(dataRow.ItemArray[0].ToString(), out number);

• Missing required line fields. if (dataRow.ItemArray[4].ToString().Length < 1)

To work through the contents of the .csv file I based my code on this code example:
