Question

I’m using a tool called filehelpers, which defines a class on the fly for purposes of file import. The class file might look like:

[DelimitedRecord(",")]
[IgnoreFirst(1)]
public class TestNoPrimaryKey
{

[FieldConverter(ConverterKind.Decimal, ".")]
[FieldQuoted()]
public decimal Value;

[FieldQuoted('"', QuoteMode.OptionalForRead, MultilineMode.AllowForRead)]
public String aString;

}

This is correctly created in code from what I can see. Next I need to create a datatable in a comparable format, so I can do a SQL insert. Through kind help on SO I have this code which accepts the type (defined above) and purports to generate the typed datatable columns for me:

public static DataTable TypeToEmptyDataTable(Type myType)
{
    DataTable dt = new DataTable();

    foreach (PropertyInfo info in myType.GetProperties())
    {
        dt.Columns.Add(new DataColumn(info.Name, info.PropertyType));
    }

    return dt;
}

Unfortunately, it does not find any properties and returns a datatable with no columns. Now I’m thinking – if the get; set; etc isn’t specified in the class maybe they aren’t ‘properties’ per se. Maybe getMembers is what I need? I tried that but returning info.MemberType did not work.

Any thoughts on how to get the names/types out of my class? I don’t believe I can add the get/set because that class layout is required by the filehelpers tool I’m using.

Thanks!

You haven’t written any properties in the code above – you’ve declared fields. The get and set does indeed make a very significant difference 🙂

If you want to get fields, just use GetFields – but I’d recommend that you make them properties instead. Properties work better in terms of binding etc, as well as generally being a better start towards encapsulation.
