问题
I want to silent extract of .rar archive. .Net haven't any Rar classes in IO.Compression, so i'd like to use cmd (it's better, than external dll). It extracts, but not in silent mode. What am I doing wrong?
const string source = "D:\\22.rar";
string destinationFolder = source.Remove(source.LastIndexOf('.'));
string arguments = string.Format(@"x -s ""{0}"" *.* ""{1}\""", source, destinationFolder);
Process.Start("winrar", arguments);

I use this bit of code myself (your code added):
const string source = "D:\\22.rar";
string destinationFolder = source.Remove(source.LastIndexOf('.'));
System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.CreateNoWindow = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "\"C:\\Program Files\\WinRAR\\winrar.exe\"";
p.StartInfo.Arguments = string.Format(@"x -s ""{0}"" *.* ""{1}\""", source, destinationFolder);
p.Start();
p.WaitForExit();
That will launch the WinRAR program in the background and return control to you once the file has completed un-rar-ing.
Hope that can help

Alternatively, you can embed with your application the tool called unRAR, the small executable developed by the WinRAR's developers (official download).
This utility is free, thus your users won't need to have a WinRAR license to use your application. :) It can be executed using the same way txtechhelp described.
