Display text containing null (0x00) bytes.

Question

I read a file containing some null characters
 
string text =   sr.ReadToEnd()
textbox.Text = text;

The problem is that textbox displays the data until it reads the first 0x00.
text.Length property has the value of file size.

Does exists any other method than parsing the string to display the text?

Answer 1

I'm not sure I see the problem here.  You're saying that the length is the length of the file size.  Sounds like you're getting the whole file.  I can't reproduce this... in fact, I tried:

string test = "This is a test... it is only a test";
byte[] bytes = Encoding.Default.GetBytes(test);
byte[] newBytes = new byte[bytes.Length + 2];
Array.Copy(bytes, newBytes, 12);
Array.Copy(bytes, 12, newBytes, 14, bytes.Length - 12);
File.WriteAllBytes(@"C:\dump\reallyGoodFile.txt", newBytes);

string file = File.ReadAllText(@"C:\dump\reallyGoodFile.txt");
Console.WriteLine(file);

Do you have code that shows your problem?

Hi David.

Console.WriteLine() displays the whole file.

Add MessageBox.Show(file);

You will see only "This is a te"

Answer 3

I see.

Use string.Replace.  Not sure why it does this, to be honest.

MessageBox.Show(file.Replace("\0", ""));
