Custom Fields Only From Sharepoint List

Is it possible to loop through field collection of a sharepoint list and retrieve only our custom fields and not the sharepoint built-in fields.

using (SPSite site = new SPSite("http://localhost/"))
{
   using (SPWeb web = site.OpenWeb())
   {
       SPList list = web.Lists["My List"];
       foreach (SPField field in list.Fields)
       {
           //We also get sharepoint built-in column here. And we don't want that, just our
           //custom created fields.
       }
   }
}

Any help would be appreciated.

Thanks

You have two options:

  1. Check if the field is a built-in field: SPBuiltInFieldId.Contains(field.Id)
  2. Check on the SPField.SourceId (from MSDN):

Gets either the namespace that defines a built-in field or, if it a custom field, the GUID that identifies the list or Web site where it was created.

Here's a contrived (and currently untested) way:

string fieldTypeClass = field.FieldTypeDefinition.FieldTypeClass;

if (!(string.IsNullOrEmpty(fieldTypeClass) || fieldTypeClass.StartsWith("Microsoft.SharePoint"))) {
//Only custom fields here
}

I don't know if its really what you're looking for, of if LINQ is still "smiled upon" by .net digirati, but using LINQ to Sharepoint might work for you.
