Question

I want to read the html file.And for that I use System.IO.File.ReadAllText(path).It can read all the html file but there is one file which is not read through this function.

I have also used

using (StreamReader reader = File.OpenText(fileName)) {
text = reader.ReadToEnd(); But still there is same problem.

What is the reason can be there ? And for that what can be the solution ? Or any other way to read the file ?

Answer 1

I’ll take a wild guess:
The file contains unicode sequences for extended chars and the diagnose is based on (mismatched) length.

if I debug the code in the it looks
like
“<\0h\0t\0m\0l\0>\0<\0h\0e\0a\0d\0>\0\r\0\n\0<\0M\0E\0T\0A\0
\0h\0t\0t\0p\0-\0e\0q\0u\0i\0v\0=\0\”\0C\0o\0n\0t\0e\0n

Which is a valid beginning of a HTML file except for the very first char. The file is probably damaged by missing a unicode marker at the start. This damage was probably caused when it was written and is not (easy) repairable now.

You could try setting the WebClient.Encoding to UTF8 (and try a few ASCII as well).
