How to read a xml string into XMLTextReader type

问题:

I have an XML string. I need to convert this string into XMLTextReader(System.Xml.XMLTextReader) type in dotnet.

I used the following code:

string szInputXml = "<TestDataXml><DataName>testing</DataName></TestDataXml>" ;
XmlTextReader reader = new XmlTextReader(new System.IO.StringReader(szInputXml));

But the string inside the reader is empty after execution.

Please help me to figure out what needs to be done to get the XMLTextReader to be populated with the given string.

回答1:

How do you determine if the string is empty?

string szInputXml = "<TestDataXml><DataName>testing</DataName></TestDataXml>";
XmlTextReader reader = new XmlTextReader( new System.IO.StringReader( szInputXml ) );
reader.Read();
string inner = reader.ReadInnerXml();

Without 3rd line "inner" was empty indeed. Now it contains testing.
