C # solution for reading the XML file "error in entityname analysis"

In the process of XML and XSLT programming, we often encounter"Analysis Entityname Error"Prompt! Actually youProgramThere are not too many errors. You just ignore the special Symbol Representation Method in XML. If this error occurs, check whether the symbol below is used and convert each other:

special characters	special meaning	entity encoding
		& gt;
		& lt;
"	double quotation marks	& quot;
'	single quotation marks	& apos;
&	"&" character	& amp;

Note: XML nodes cannot contain these special characters, such as "&", "<", ">". Otherwise, the XML will report an error during parsing. You need to convert it for use.
