When dataset is written into the memory stream using the writexml method of dataset, the Declaration line of the XML document is missing.

When dataset is written into the memory stream using the writexml method of dataset, the Declaration line of the XML document is missing.

Dataset. writexml (memorystream, xmlwritemode. writeschema). After writing, memorystream does not contain the declaration part of the first line of the XML document.

Solution: Write the Declaration line in memorystream.

Sample Code:

 

Memorystream content = new memorystream ();

Streamwriter Sw = new streamwriter (content );

// When writing a dataset into the memory stream using the writexml method of dataset, the statement line of the XML document is missing and must be added first.
Sw. writeline (@ "<? XML version = "1.0" standalone = "yes"?> ");
Sw. Flush ();

Dataset. writexml (content, xmlwritemode. writeschema );
