Implement mutual conversion between XML and datatable. net

The following two functions are exchanged between XML and datatable:

 
Private StringConvertdatatabletoxml (datatable xmlds)
 

 
{
 

 
Memorystream stream =Null;
 

 
Xmltextwriter writer =Null;
 

 
Try
 

 
{
 

 
Stream =NewMemorystream ();
 

 
Writer =NewXmltextwriter (stream, encoding. Default );
 

 
Xmlds. writexml (writer );
 

 
IntCount = (Int) Stream. length;
 

 
Byte[] Arr =New Byte[Count];
 

 
Stream. Seek (0, seekorigin. Begin );
 

 
Stream. Read (ARR, 0, count );
 

 
Utf8encoding UTF =NewUtf8encoding ();
 

 
ReturnUTF. getstring (ARR). Trim ();
 

 
}
 

 
Catch
 

 
{
 

 
ReturnString. empty;
 

 
}
 

 
Finally
 

 
{
 

 
If(Writer! =Null) Writer. Close ();
 

 
}
 

 
}
 

PrivateDataset convertxmltodataset (StringXmldata)
 

 
{
 

 
Stringreader stream =Null;
 

 
Xmltextreader reader =Null;
 

 
Try
 

 
{
 

 
Dataset xmlds =NewDataset ();
 

 
Stream =NewStringreader (xmldata );
 

Reader =NewXmltextreader (Stream );
 

 
Xmlds. readxml (Reader );
 

 
ReturnXmlds;
 

 
}
 

 
Catch(Exception ex)
 

 
{
 

 
StringStrtest = ex. message;
 

 
Return Null;
 

 
}
 

Finally
 

 
{
 

 
If(Reader! =Null)
 

 
Reader. Close ();
 

 
}
 

 
}
