convert XmlReader to XmlTextReader
How do you convert XmlReader to XmlTextReader?
Code Snippet:
XmlTextReader reader = XmlTextReader.Create(pomfile.FullName);
Here's the Build error I got:
Cannot implicitly convert type 'System.Xml.XmlReader' to 'System开发者_Go百科.Xml.XmlTextReader'. An
explicit conversion exists(are you missing a cast?).
pomfile is of type FileInfo
XmlTextReader.Create()
function produces XMLReader that you have to cast to XmlTextReader
but this can produce runtime exception if the cast is impossible:
XmlTextReader tr = (XmlTextReader)XmlTextReader.Create(pomfile.FullName));
or you can do this:
XmlTextReader reader = new XmlTextReader(XmlTextReader.Create(pomfile.FullName));
but the best thing to do is:
XmlTextReader reader = new XmlTextReader(pomfile.FullName);
XmlTextReader
is obsolete in .NET 2.0. Just do this instead:
XmlReader reader = XmlReader.Create(pomfile.FullName);
XmlReader
is the abstract base class of XmlTextReader
so you would need to force a downcast (which I would not advise).
Instantiate the class you are expecting directly (as pointed out in najmeddine's answer)
