Update Yes/No Custom Field SOAP API C#

Content

Hi,

I'm trying to update a Yes/No Custom Filed using the SOAP API in C# and it is not working can you please help.

I was able to successfully update Integer, string and menu however, the Yes/No is not working for me below is my code.

For the Int type:

                        GenericField customField = new GenericField();
                        customField.name = "oracleid";
                        customField.dataType = DataTypeEnum.INTEGER;
                        customField.dataTypeSpecified = true;
                        customField.DataValue = 1;
                        GenericObject customFieldsc = new GenericObject();

String 

                        GenericField customField = new GenericField();
                        customField.name = "oracleName";
                        customField.dataType = DataTypeEnum.STRING;
                        customField.dataTypeSpecified = true;
                        customField.DataValue = "AMMAR";
                        GenericObject customFieldsc = new GenericObject();

Menu 

                       GenericField customField = new GenericField();
