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));
