csvhelper

I am trying to read a CSV file with CsvHelper, load each record into a DataTable, and then use SqlBulkCopy to insert the data into a database table. With the current code, I get an exception when adding a row to the DataTable. The exception is: "Unable to cast object of type 'MvcStockAnalysis.Models.StockPrice' to type 'System.IConvertible'.Couldn't store in Date Column. Expected type is DateTime." The example CSV file is from yahoo finance. For example: http://ichart.yahoo.com/table.csv?s=MMM&a=0&b=1&c=2010&d=0&e=17&f=2014&g=d&ignore=.csv The CSV file contains the following header: Date Open

I have some really lame Csv files I need to parse. I am using CsvHelper and it is working awesome. Except I have some lines that have whitespace where normaly I have a double. File: Text,SomeDouble,MoreText "Good",1.23,"Good" "Bad", ,"Bad" if I try and map this into public class Test { [CsvField(Name = "Text")] public string Text { get; set; } [CsvField(Name = "SomeDouble")] public double? SomeDouble{ get; set; } [CsvField(Name = "MoreText")] public string MoreText{ get; set; } } then I get an error like this: CsvHelper.CsvReaderException: An error occurred trying to read a record of type Row:

I am using the class CsvReader successfully and am happy with it, however, the file that I consume is being produced by a group which changes column formats without letting me know. So, one moment everything is working, then the next morning things break and the try catch block around csv.GetRecord<MyType>() catches the error and logs the error, however I can't gather any valuable info from the Exception instance. It just says: "The conversion cannot be performed." and the InnerException has nothing. Not very useful. I don't even know which one of my 150 columns are causing the problem. Can

I'm using CsvHelper to serialize a class to csv file - until here everything works well. Now I'm trying to find a way to convert the class's enum properties to their int value in the csv, so I could use the CSV for bulk insert later. I found out the EnumConverter class in CsvHelper but I can't figure out how to properly use it, as all my tries are failing. Here is my mapping class code public sealed class MyMapping : CsvClassMap<TradingCalendarException> { public MyMapping() { EnumConverter enumConverter = new EnumConverter(typeof(CalendarExceptionEntityType)); Map(m => m.ExceptionEntityType)

I am trying to use the CSVhelper plugin to read an uploaded CSV file. Here is my modelBinder class: public class SurveyEmailListModelsModelBinder : DefaultModelBinder { public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var csv = bindingContext.ValueProvider.GetValue(bindingContext.ModelName); var file = ((csv.RawValue as HttpPostedFileBase[]) ?? Enumerable.Empty<HttpPostedFileBase>()).FirstOrDefault(); if (file == null || file.ContentLength < 1) { bindingContext.ModelState.AddModelError( "", "Please select a valid CSV file" ); return
