Using SearchBooleanCustomField C# .Net

I spent forever and a day figuring out how to search by a custom field and status on a sales order. I couldn't find any samples on this forum so I wanted to share hoping to save someone else new to this web service some time. My custom field was a check box but i'm assuming same logic should apply to other field types.

Code Snippet C# .Net:

SearchBooleanCustomField custField = new SearchBooleanCustomField();
            custField.internalId=("custbody4");
            custField.searchValue = false;
            custField.searchValueSpecified = true;
            SearchCustomField[] CustFieldArray = new SearchCustomField[1];
            CustFieldArray[0] = custField;

            xactionBasic.type = soField;
            xactionBasic.status = statusField;
            xactionBasic.customFieldList = CustFieldArray;
            xactionSearch.basic = xactionBasic;
         
            SearchResult SOResults = service.search(xactionSearch);
