    Get domain string from a field
    public string GetDomainStringFromField(Row row, Field field)
    {
      // Get the table and table definition from the Row
      using (Table table = row.GetTable())
      using (TableDefinition tableDefinition = table.GetDefinition())
      {
        // Get name of subtype field
        string subtypeFieldName = tableDefinition.GetSubtypeField();
    
        // Get subtype, if any
        Subtype subtype = null;
    
        if (subtypeFieldName.Length != 0)
        {
          // Get value of subtype field for this row
          object varSubtypeCode = row[subtypeFieldName];
          long subtypeCode = (long)varSubtypeCode;
    
          // Get subtype for this row
          subtype = tableDefinition.GetSubtypes().First(x => x.GetCode() == subtypeCode);
        }
    
        // Get the coded value domain for this field
        CodedValueDomain domain = field.GetDomain(subtype) as CodedValueDomain;
    
        // Return the text string for this field
        if (domain != null)
        {
          return domain.GetName(row[field.Name]);
        }
        else
        {
