C Iterate through Class properties

Question

I m currently setting all of the values of my class object Record   This is the code that I m using to populate the record at the moment  property by property      Loop through each field in the result set for  int i   0  i  lt   resultItems Length  i           Record newRecord   new Record                     itemtype     resultItems i -  fieldCount - 0                itemdesc     resultItems i -  fieldCount - 1                prodcode     resultItems i -  fieldCount - 2                proddesc     resultItems i -  fieldCount - 3                curstat      resultItems i -  fieldCount -4                totfree      resultItems i -  fieldCount -5                totphys      resultItems i -  fieldCount -6                pcolgroup    resultItems i -  fieldCount -7                scolgroup    resultItems i -  fieldCount -8                totpo        resultItems i -  fieldCount - 9                totso        resultItems i -  fieldCount - 10                quality      resultItems i -  fieldCount - 11                statusdesc   resultItems i -  fieldCount - 12                groupcode    resultItems i -  fieldCount - 13                qualitydes   resultItems i -  fieldCount - 14                pcoldesc     resultItems i -  fieldCount - 15                scoldesc     resultItems i -  fieldCount - 16                pgroupdesc   resultItems i -  fieldCount - 17               Can I iterate through each of the properties dynamically without hard coding all of the property names   Something like so      Create new Record instance Record newRecord   new Record     for  int e   0  e  lt  propertyCount Length - 1  e          newRecord fieldname    resultItems i -  fieldCount - e

You could possibly use Reflection to do this. As far as I understand it, you could enumerate the properties of your class and set the values. You would have to try this out and make sure you understand the order of the properties though. Refer to this MSDN Documentation for more information on this approach.

For a hint, you could possibly do something like:

Record record = new Record();

PropertyInfo[] properties = typeof(Record).GetProperties();
foreach (PropertyInfo property in properties)
{
    property.SetValue(record, value);
}

Where value is the value you're wanting to write in (so from your resultItems array).

Yes  you could make an indexer on your Record class that maps from the property name to the correct property  This would keep all the binding from property name to property in one place eg   public class Record       public string ItemType   get  set         public string this string propertyName                set                       switch  propertyName                                case  itemType                       ItemType   value                      break                         etc                                      Alternatively  as others have mentioned  use reflection

I tried what Samuel Slade has suggested  Didn t work for me  The PropertyInfo  list was coming as empty  So  I tried the following and it worked for me       Type type   typeof Record       FieldInfo   properties   type GetFields        foreach  FieldInfo property in properties           Debug LogError property Name

the index of each item in fieldNames must correspond to     the correct index in resultItems var fieldnames   new     itemtype    etc etc      for  int e   0  e  lt  fieldNames Length - 1  e          newRecord         GetType           GetProperty fieldNames e           SetValue newRecord  resultItems e
