filehelpers

I built a program using FileHelpers to parse CSV files and it works wonders, except I'm running into an issue. Some of the files - but not all - have a number of extra lines in the end with information that does not pertain to actual fields. like so ... 31,4104019, ,,1043,,,0,,Ventas Total Credito,1,1,277.98,0,0,0,0,21.5040000000,V, 31, ,11212302,,1043,,,0,,Ventas Total Credito,1,1,33.28,0,0,0,0,21.5040000000,V, 31, ,11212307,,1043,,,0,,Ventas Total Credito,1,1,277.98,0,0,0,0,21.5040000000,V, ;Importado="01/11/2013" //blank line here too I know FileHelpers has the [IgnoreLast(3)] public class

I am using FileHelpers to import data from a CSV file. Problem is, some versions of the CSV file have more fields than others. As such, I have marked the fields that are sometimes missing as being optional, but this does not seem to work as instead of just ignoring when fields are missing (which it seems to do ok) it is also always chopping the last character off of the last field that is present. For example... a row containing "ABC,DEF,GHI" (without the quotes) imports as "ABC", "DEF" & "GHI" a row containing "ABC,DEF" (again without the quotes) imports as "ABC" & "DE" My record format is

I try to read a csv file. my fifth record contans a date: 03/11/2008 This is a piece of my code: [FieldConverter(ConverterKind.Date, "dd/MM/yyyy")] public DateTime datum_5; My code crashs on this: Result[] results= (Result[])engine.ReadFile(@"..\Data\expo.txt"); And with this exception: Line: 1. Column: 41. Field: datum_5. Error Converting '03/11/2008' to type: 'DateTime'. Using the format: 'dd/MM/yyyy' When i do this: [FieldConverter(typeof(ConvertDate))] public DateTime datum_5; with this: internal class ConvertDate : ConverterBase { /// <summary> /// different forms for date separator : .

This morning I embarked on what I thought would be a quick exercise to use custom field attributes. Having tried many things and searching many examples (most involving class rather than field attributes), I'm officially stuck. My code is below. One peculiarity is that the class is built in FileHelpers using the classbuilder. My various partially successful attempts did manage to get the fieldnames from this class though, so I believe that part works fine. What I want to do (per the comment in the code) is a) Run through the fields, b) for each, see if the DBDataTypeAttribute Attribute exists,

I'm using version 2.0 of the FileHelpers library which is documented as being able to handle .NET 2.0 Nullable types. I'm using the code given in the example from the documentation: [DelimitedRecord("|")] public class Orders { public int OrderID; public DateTime? OrderDate; [FieldConverter(ConverterKind.Date, "ddMMyyyy")] public DateTime? RequiredDate; public int? ShipVia; } With a FileHelperEngine I can successfully read in a file which has no value for the OrderDate, RequiredDate or ShipVia fields. The file looks like: 1||| However, I cannot then write out the resulting Orders[] to file -

Code below is used to read fixed width uploaded file content text file using FileHelpers in ASP .NET MVC2 First and last line lengths are smaller and ReadStream causes exception due to this. All other lines have proper fixed width. How to skipt first and last lines or other way to read data without exception ? [FixedLengthRecord()] class Bank { [FieldFixedLength(4)] public string AINETUNNUS; [FieldFixedLength(16)] public string TEKST1; [FieldFixedLength(3)] public string opliik; [FieldFixedLength(2)] public string hinnalis; }; [AcceptVerbs(HttpVerbs.Post)] [Authorize] public ActionResult

I'm looking to export a large SQL Server table into a CSV file using C# and the FileHelpers library. I could consider C# and bcp as well, but I thought FileHelpers would be more flexible than bcp. Speed is not a special requirement. OutOfMemoryException is thrown on the storage.ExtractRecords() when the below code is run (some less essential code has been omitted): SqlServerStorage storage = new SqlServerStorage(typeof(Order)); storage.ServerName = "SqlServer"; storage.DatabaseName = "SqlDataBase"; storage.SelectSql = "select * from Orders"; storage.FillRecordCallback = new FillRecordHandler
