Usage

Basic usage

Navigate to the directory of your .csproj and run the tool passing the source csv file to scaffold

csv2class -i myCsvFilePath.csv

By default, it assumes that your csv don't have a header, and the columns and properties will be named in sequence "Column 0", "Column 1"... If your csv has a header row, add the -h switch. The header is used to get the name of the properties and are used in the Display attribute from ASP.NET MVC and Name attribute from CsvHelper

csv2class -i myCsvFilePath.csv -h

The default delimiter is the current culture list separator from your system. To change that, use the -s option

csv2class -i myCsvFilePath.csv -s ;
csv2class -i myCsvFilePath.csv -s \t
csv2class -i myCsvFilePath.csv -s ,

The csproj file is used to guess the namespace. As an alternative, you can explicit set the namespace of the generated classes:

csv2class -i myCsvFilePath.csv -p MyNamespace

The csv file name will be used for the class name. You can specify your own class name with the -c option

csv2class -i myCsvFilePath.csv -c MyClass

To specify the output directory where the files will be saved, use the -o option. The directory will be created, if it doesn't exist.

csv2class -i myCsvFilePath.csv -o OutputDir

To guess the double and DateTime data types, it is used the Invariant Culture. To specify a culture, use the -t option

csv2class -i myCsvFilePath.csv -t en-US 

To generate the ASP.NET MVC Display attribute, use the -d switch

csv2class -i myCsvFilePath.csv -d 

To generate the CsvHelper Index and Name attributes, use the -x and/or n switches, respectively

csv2class -i myCsvFilePath.csv -x
csv2class -i myCsvFilePath.csv -n
csv2class -i myCsvFilePath.csv -xn

The default is to generate CsvHelper attributes. If you wish to use the ClassMap intead, use the -m switch. It will be generate a file in the same folder of the class file, with the name {Class}Map

csv2class -i myCsvFilePath.csv -xm
csv2class -i myCsvFilePath.csv -n -m
csv2class -i myCsvFilePath.csv -xnm
