c#:boolean values not getting converted when coverting from object to xml

I am trying to convert object to xml. i have written a class which converts object to xml. in my object i have boolean and string variables. But when i convert only string variable a getting converted and not boolean. Please help me to resolve this issue. Below is my code.

LocateRequest stockLoanRequest = new LocateRequest();
stockLoanRequest.acceptManualApproval = false;
stockLoanRequest.acceptPartial = false;
stockLoanRequest.market = "US";
stockLoanRequest.cashOrSwap = cashOrSwapType.CASH;
stockLoanRequest.requestedQuantity = request.shares.ToString();
stockLoanRequest.requestorReference = request.locateId;
stockLoanRequest.securityId = request.symbol;
stockLoanRequest.securityIdentifierType = securityIdentifierType.TICKER;
return stockLoanRequest;
            

Convert object to xml code:

public static string convertRequestToXML(Object obj)
{
    XmlSerializer serializer = null;
     StringWriterUTF8 sw = new StringWriterUTF8();

     XmlTextWriter tw = null;
     try
     {
         serializer = new XmlSerializer(obj.GetType());
         tw = new XmlTextWriter(sw);
         tw.Formatting = Formatting.Indented;
         serializer.Serialize(tw, obj);
     }
     catch (Exception ex)
     {
         //Handle Exception Code
     }
     finally
     {
         sw.Close();
         if (tw != null)
         {
             tw.Close();
         }
     }

     return sw.ToString();
 }

Output to xml looks like below:

<LocateRequests>
    <LocateRequest securityId="IBM" securityIdentifierType="TICKER" market="US" requestedQuantity="1" requestorReference="34" />
</LocateRequests>

I don't see the boolean values acceptManualApproval and acceptPartial getting in the above output.

Below is the locate request class:

public partial class LocateRequest 
{        
    private bool acceptManualApprovalField;       
    private bool acceptManualApprovalFieldSpecified;       
    private bool acceptPartialField;       
    private bool acceptPartialFieldSpecified;      
    private string securityIdField;        
    private securityIdentifierType securityIdentifierTypeField;       
    private string marketField;        
    private string requestedQuantityField;        
    private string requestorReferenceField;        
    private cashOrSwapType cashOrSwapField;        
    private bool cashOrSwapFieldSpecified;
