I'm currently trying to parse a value from a csv file that is a boolean. We've noticed that the value will successfully parse Yes and Y (in any case) but will not parse No and N I'm mapping the value in the classmap like this: Map(m => m.Enabled).Name("Enabled").TypeConverterOption(false, string.Empty); Is there a reason why this would read Yes but not No and is there a way to add the ability to parse no ? In version 4.0.3, this works. void Main() { using (var stream = new MemoryStream()) using (var writer = new StreamWriter(stream)) using (var reader = new StreamReader(stream)) using (var csv

When parsing a csv file, how do i define that a specific field is mandatory. Essentially, I want to make sure that a given field is never empty, and if it is then I would like an exception thrown. Here is the mapping class: public sealed class DataMapper : CsvClassMap<DataType> { public DataMapper() { Map(m => m.Field1).Name("FirstField"); Map(m => m.Field2).Name("SecondField"); Map(m => m.Field3).Name("ThirdField"); // this field should be mandatory } } and the usage: List<DataType> data; using (var sr = new StreamReader(localFilePath)) { var reader = new CsvReader(sr); reader.Configuration

If I have some LF converted (using N++) CSV files, everytime I write data to them using JoshClose's CsvHelper the line endings are back to CRLF. Since I'm having problems with CLRF ROWTERMINATORS in SQL Server, I whish to keep my line endings like the initital status of the file. Couldn't find it in the culture settings, I compile my own version of the library. How to proceed? From what I can tell, the line terminator isn't controlled by CvsHelper. I've gotten it to work by adjusting the File writer I pass to CsvWriter. TextWriter tw = File.CreateText(filepathname); tw.NewLine = "\n";

I would like to be able to iterate through all records in a CSV file and add all the good records to one collection and handle all the "bad" ones separately. I don't seem to be able to do this and I think I must be missing something. If I attempt to catch the BadDataException then subsequent reads will fail meaning I cannot carry on and read the rest of the file - while (true) { try { if (!reader.Read()) break; var record = reader.GetRecord<Record>(); goodList.Add(record); } catch (BadDataException ex) { // Exception is caught but I won't be able to read further rows in file // (all further

I'm using CsvHelper class to write rows in DataTable to a csv file. The code works but I can't get it to write the headers. How can I add the headers manually without creating a Class Map? http://joshclose.github.io/CsvHelper/ DataTable dt = GetDataTableFromDB(); System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(); System.IO.StreamWriter streamWriter = new System.IO.StreamWriter( memoryStream ); CsvHelper.CsvWriter writer = new CsvHelper.CsvWriter( streamWriter ); foreach ( DataColumn column in properties.Columns ) writer.WriteHeader( column.ColumnName ); //<--- How do I write

I have a worker with various fields that are fetched from server. I am using CSVHelper package to convert this class to an excel sheet. Worker has Fields like : class Worker { string name; string phone; string age; Dictionary<string,object> customerField; } I can map the name, phone, number like class WorkerMap : CsvClassMap<Worker> { public WorkerMap() { Map(m => m.name); Map(m => m.phone); Map(m => m.age); } } And I generate the map by : csv.Configuration.RegisterClassMap<WorkerMap>(); Write the list of workers by : csv.WriteRecords(workerList); How can I map the customerField dictionary to
