c# - How to read text files with ANSI encoding and non-English letters?

Question

I have a file that contains non-English chars and was saved in ANSI encoding using a non-English codepage. How can I read this file in C# and see the file content correctly?

Not working

StreamReader sr=new StreamReader(@"C:APPLICATIONS.xml",Encoding.ASCII);
var ags = sr.ReadToEnd();
sr=new StreamReader(@"C:APPLICATIONS.xml",Encoding.UTF8);
ags = sr.ReadToEnd();
sr=new StreamReader(@"C:APPLICATIONS.xml",Encoding.Unicode);
ags = sr.ReadToEnd();

Working but I need to know what is the code page in advance, which is not possible.

sr=new StreamReader(@"C:APPLICATIONS.xml",Encoding.GetEncoding(1252));
ags = sr.ReadToEnd();

Answer 1

 var text = File.ReadAllText(file, Encoding.GetEncoding(codePage));
