serialization - C# - How to serialize and derialize DataSet correctly? -

i cannot deserialize serialized dataset correctly if has dates. result dates considered separate table instead of columns itself. seems not parsed correctly. how fix this?

here variables under inspection after serialization , deserialization. can see deserializeddataset.tables has 2 counts original 1 count. printed table names , shows second table date. moreover, can access date column in original data set unable access in deserialized version.

here serialized data of dataset.

<?xml version="1.0" standalone="yes"?> <newdataset>   <producttransactionsummary>     <id>74517</id>     <branchid>9999</branchid>     <date xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema">       <year>2016</year>       <month>11</month>       <day>10</day>       <hour>18</hour>       <minute>25</minute>       <second>40</second>       <millisecond>0</millisecond>     </date>   </producttransactionsummary>   <producttransactionsummary>     <id>74518</id>     <branchid>9999</branchid>     <date xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema">       <year>2016</year>       <month>11</month>       <day>10</day>       <hour>18</hour>       <minute>25</minute>       <second>40</second>       <millisecond>0</millisecond> </newdataset> 

here deserialized dataset.

<?xml version="1.0" standalone="yes"?> <newdataset>   <producttransactionsummary>     <id>74517</id>     <branchid>9999</branchid>     <date>       <year>2016</year>       <month>11</month>       <day>10</day>       <hour>18</hour>       <minute>25</minute>       <second>40</second>       <millisecond>0</millisecond>     </date>   </producttransactionsummary>   <producttransactionsummary>     <id>74518</id>     <branchid>9999</branchid>     <date>       <year>2016</year>       <month>11</month>       <day>10</day>       <hour>18</hour>       <minute>25</minute>       <second>40</second>       <millisecond>0</millisecond>     </date>   </producttransactionsummary> </newdataset> 

here current code:

public static class transport {     public static memorystream serialize(dataset dataset)     {         var memorystream = new memorystream();         dataset.writexml(memorystream, xmlwritemode.ignoreschema);         dataset.writexml("input.xml");         memorystream.flush();         memorystream.position = 0;         return memorystream;     }      public static dataset deserialize(memorystream stream)     {         var dataset = new dataset();         dataset.readxml(stream);         dataset.writexml("output.xml");         return dataset;     } }
