Use WinRAR in C # to encrypt and compress files

Use WinRAR in C # to encrypt and compress files

This example mainly implements:

1. compress the folder and its files

2. compress files in a folder

3. the compressed folder and its files are rar or zip

4. Extract

5. Encrypted compression and unencrypted Compression

-----------

The sample code is as follows:

?

Protected void button#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

/// Compress c:/freezip/free.txt (that is, the folder and its files freezip/free.txt)

//// To c:/freezip/free.rar

// StrzipPath = "C: // freezip // free"; // The default compression mode is. rar.

// Process1.StartInfo. Arguments = "a-r" + strzipPath + "" + strtxtPath;

/// 2

/// Compress c:/freezip/free.txt (that is, the folder and its files 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

/// Compress c:/freezip/free.txt (that is, the folder and its files freezip/free.txt)

/// Directly set free.zip to c:/freezip/free.zip

// Process1.StartInfo. Arguments = "a-r" + strzipPath + "" + strtxtPath;

/// 4

/// Migrate and compress c:/freezip/free.txt (that is, the folder and its files freezip/free.txt)

/// To c:/freezip/free.rar after compression, the original file will not exist

// Process1.StartInfo. Arguments = "m" + strzipPath + "" + strtxtPath;

/// 5

/// Compress c:/freezip/free.txt(file free.txt)

/// To c:/freezip/free.zip, set it to free.zip. Only files are available, but no folders are available.

// Process1.StartInfo. Arguments = "a-ep" + strzipPath + "" + strtxtPath;

/// 6

//// Decompress c:/freezip/free.rar

/// To c:/freezip/

// StrtxtPath = "c: // freezip //";

// Process1.StartInfo. Arguments = "x" + strzipPath + "" + strtxtPath;

/// 7

//// Encrypted compression c:/freezip/free.txt (that is, the folder and its files freezip/free.txt)

//// The password for connecting to c:/freezip/free.zip is 123456. Note that no space is required between parameters.

// Process1.StartInfo. Arguments = "a-p123456" + strzipPath + "" + strtxtPath;

/// 8

//// Decompress the encrypted c:/freezip/free.rar

//// To c:/freezip/the password is 123456. Do not set spaces between parameters.

// StrtxtPath = "c: // freezip //";

// Process1.StartInfo. Arguments = "x-p123456" + strzipPath + "" + strtxtPath;

Process1.Start ();

If (Process1.HasExited)

{

Response. Write ("finished ");

}

}
