How can I read a Lync dialog file containing HTML?

Question

How can I read a Lync dialog file containing HTML?

I'm having trouble reading a local file into a string in C #.

Here is what I came up with so far:

 string file = @"C:\script_test\{5461EC8C-89E6-40D1-8525-774340083829}.html";
 using (StreamReader reader = new StreamReader(file))
 {
      string line = "";
      while ((line = reader.ReadLine()) != null)
      {
           textBox1.Text += line.ToString();
      }
 }

And this is the only solution that seems to work.

I tried some other suggested methods for reading a file, for example:

string file = @"C:\script_test\{5461EC8C-89E6-40D1-8525-774340083829}.html";
string html = File.ReadAllText(file).ToString();
textBox1.Text += html;

However, it does not work properly.

Here are the first few lines of the file I'm trying to read:

as you can see, he has some funky characters, to be honest, I don’t know if this strange behavior is the cause.

But in the first case, the code seems to skip these lines, printing only "Document created by Office Communicator ..."
