Hi Romeo,

You'll want something like this:

    private IEnumerable<Record> GetEntries(Guid formId, Guid fieldId, string requiredValue)
    {
        using (var formStorage = new FormStorage())
        {
            using (var recordStorage = new RecordStorage())
            {
                Form form = formStorage.GetForm(formId);
                // get all records (entries) for that form
                IEnumerable<Record> records = recordStorage.GetAllRecords(form);

                return records.Where(x => x.RecordFields[fieldId].ValuesAsString() == requiredValue);
            }
        }
    }

For this you'll need the Guid for the form, and for the field which you wish to query. You'll also need usings for Umbraco.Forms.Core and Umbraco.Forms.Data.Storage.

Regards,

Tim
