C # Use WinRAR (encrypted) to compress and decompress related folders and files

the main implementation of this example:
1. compressing folders and their files
2. compressing files in a folder
3. the compressed folder and its files are RAR or zip
4. decompress
5.
-----------
example Code :
protected void button#click (Object sender, eventargs e)
{< br> string strtxtpath = "C :\\ freezip \ free.txt";
string strzippath = "C: \ freezip \ free.zip ";
system. diagnostics. process process1 = new system. diagnostics. process ();
process1.startinfo. filename = "winrar.exe";
