## Remarks  
 The query options are added to the resultant URI using `?name=value&name2=value2`… syntax where the name maps directly to the `name` parameter and the `value` is obtained by calling ToString on the `value` parameter. The `name` starts with `$`.  
  
 Non-WCF Data Services syntax does not start with `$`. Non-WCF Data Services query options can be added using this method. It is legal to add the same query option twice if the option is not an WCF Data Services query option. If a query option is added that is already present in the underlying URI, an exception is thrown.  
  
   
  
## Examples  
 The following example shows a <xref:System.Data.Services.Client.DataServiceQuery%601> that is used with sequential <xref:System.Data.Services.Client.DataServiceQuery%601.AddQueryOption%2A> method calls to only return orders with a freight cost of more than $30 and to order the results by the ship date in descending order.

## Remarks  
 When the <xref:System.Data.Services.Client.DataServiceQuery%601.System%23Collections%23IEnumerable%23GetEnumerator%2A> method is called, the <xref:System.Data.Services.Client.DataServiceQuery%601> is executed against the service.  
  
 <xref:System.Data.Services.Client.DataServiceQuery%601.GetEnumerator%2A> returns an enumerable the first time it is called. On successive calls it returns null.
