How to change the encoding of a txt file?

[hamidfirooze]

Hi
I want to read a txt file and write its contents into a textbox. The problem is that the content of txt file is not in English and I have to change the encoding. So how could I change the encoding to utf-8 in my code?
Thank you.

What is the original encoding?

Hi Samuel
The original encoding is ANSI.
By the way,I used this code, but it didn't work.

string s = File.ReadAllText("C:\\1.txt", System.Text.UTF8Encoding.UTF8);
textBox1.Text = s;

This should do the conversion fine:

 //str is the contents of your file.
Encoding ANSI = Encoding.GetEncoding(1252);
 
byte[] ansiBytes = ANSI.GetBytes(str);
byte[] utf8Bytes = Encoding.Convert(ANSI, Encoding.UTF8, ansiBytes);
 
String utf8String = Encoding.UTF8.GetString(utf8bytes);
 

I presume you already know how to read a text file.

Sam.
