Pobiega•10mo ago

using (TextFieldParser parser = new TextFieldParser(@"C:\Users\SemvanHaaften\source\repos\Vehicles\CollectionClasses\cars.csv"))
            {
                parser.TextFieldType = FieldType.Delimited;
                parser.SetDelimiters(";");
                while (!parser.EndOfData)
                {
                    //Processing row
                    string[] fields = parser.ReadFields();
                    Console.WriteLine(parser.ReadLine());


                    Console.WriteLine();
                }
            }

          
using (TextFieldParser parser = new TextFieldParser(@"C:\Users\SemvanHaaften\source\repos\Vehicles\CollectionClasses\cars.csv"))
            {
                parser.TextFieldType = FieldType.Delimited;
                parser.SetDelimiters(";");
                while (!parser.EndOfData)
                {
                    //Processing row
                    string[] fields = parser.ReadFields();
                    Console.WriteLine(parser.ReadLine());


                    Console.WriteLine();
                }
            }

okay, and you are trying to write parser.ReadFields();?

Zomboos•10mo ago

no that part is something i forgot to remove to be honest i was seeing what fields were and looking at everything parser can do wait i think uve actually helped me

Pobiega•10mo ago

uhm.. is TextFieldParser actually Microsoft.VisualBasic.FileIO.TextFieldParser?

Zomboos•10mo ago

now i think about it i can split the string into an array with the ; ye

Pobiega•10mo ago

oh, okay. I mean, I thought you were writing a csv parser from scratch TFP is essentially feature complete, if a bit more basic than CsvHelper ReadFields should handle the splitting for you remember that string.Split returns string[] just like ReadFields does

Zomboos•10mo ago

alright thanks that will help me on my way ye so reading the line and then reading the fields worked thanks
