Reading csv file into a DataTable using C#?
I have a number of Python scripts I wrote a while back, to do some data munging. I need to 'port' some of those scripts to C#.
Python provides a CSV module which facilitates importing CSV data from file into a dictionary. I want to have the same functionality in my library, but since I am new to C#, decided to come in here to ask for the best practices way to import CSV data into a DataTable.
Do I rol开发者_JS百科l my own, or is there a 'CSV module' ala Python?
I wouldn't try to roll your own. You'll have your work cut out trying to cope with all the weird corner-cases that CSV files can throw at you.
I would recommend Sébastien Lorion's Fast CSV Reader instead:
using (var csv = new CachedCsvReader(new StreamReader(filePath), true))
{
DataTable Table = new DataTable();
Table.Load(csv);
}
I didn't find any built-in .NET (this is when I coded my solution in .NET 2.0) features that satisfied my needs, so I used the open source link below. I process about 36000 files a month, it works well and I've yet to have an issue.
