Encryption compression and decompression of files using WinRAR in C

This example mainly implements:
1. Compress the folder and its files
2. Compress the files in the folder
3. Is the compressed folder and its files rar or zip
4. Decompress
5. Encryption compression and de-encryption compression
-----------
The sample code is as follows:

protected void Button1_Click(object sender, EventArgs e)
  {
    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";
    Process1.StartInfo.CreateNoWindow = true;

    //// 1
    //// Compression c:/freezip/free.txt( That is, folders and files under them freezip/free.txt)
    //// To c:/freezip/free.rar
    //strzipPath = "C://freezip//free";// The default compression method is  .rar
    //Process1.StartInfo.Arguments = " a -r " + strzipPath + " " + strtxtPath;

    //// 2
    //// Compression c:/freezip/free.txt( That is, folders and files under them freezip/free.txt)
    //// To c:/freezip/free.rar
    //strzipPath = "C://freezip//free";// Set the compression mode to  .zip
    //Process1.StartInfo.Arguments = " a -afzip " + strzipPath + " " + strtxtPath;

    //// 3
    //// Compression c:/freezip/free.txt( That is, folders and files under them freezip/free.txt)
    //// To c:/freezip/free.zip  Directly set to free.zip
    //Process1.StartInfo.Arguments = " a -r "+strzipPath+" " + strtxtPath ;

    //// 4
    //// Relocation compression c:/freezip/free.txt( That is, folders and files under them freezip/free.txt)
    //// To c:/freezip/free.rar  After compression   The original file will not exist 
    //Process1.StartInfo.Arguments = " m " + strzipPath + " " + strtxtPath;

    //// 5
    //// Compression c:/freezip/ Under free.txt( I.e. documents free.txt)
    //// To c:/freezip/free.zip  Directly set to free.zip  Files only   Without a folder 
    //Process1.StartInfo.Arguments = " a -ep " + strzipPath + " " + strtxtPath;

    //// 6
    //// Decompression c:/freezip/free.rar
    //// To  c:/freezip/
    //strtxtPath = "c://freezip//";
    //Process1.StartInfo.Arguments = " x " + strzipPath + " " + strtxtPath;

    //// 7
    //// Encryption compression c:/freezip/free.txt( That is, folders and files under them freezip/free.txt)
    //// To c:/freezip/free.zip  Password is 123456  Be careful not to have spaces between parameters 
    //Process1.StartInfo.Arguments = " a -p123456 " + strzipPath + " " + strtxtPath;

    //// 8
    //// Decompressed encrypted c:/freezip/free.rar
    //// To  c:/freezip/   Password is 123456  Be careful not to have spaces between parameters 
    //strtxtPath = "c://freezip//";
    //Process1.StartInfo.Arguments = " x -p123456 " + strzipPath + " " + strtxtPath;

    Process1.Start();  
    if (Process1.HasExited)
    {
      Response.Write(" Finish ");
    }
  }
