C# 利用WinRAR (加密)压缩及解压缩 相关文件夹及文件

本次示例主要实现：

1.压缩文件夹及其下文件

2.压缩文件夹下文件

3.压缩文件夹及其下文件为rar 还是 zip

4.解压缩

5.加密压缩及解加密压缩

-----------

示例代码如下：

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

////压缩c:\freezip\free.txt(即文件夹及其下文件freezip\free.txt)

////到c:\freezip\free.rar

//strzipPath = "C:\\freezip\\free";//默认压缩方式为 .rar

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

//// 2

////压缩c:\freezip\free.txt(即文件夹及其下文件freezip\free.txt)

////到c:\freezip\free.rar

//strzipPath = "C:\\freezip\\free";//设置压缩方式为 .zip

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

//// 3

////压缩c:\freezip\free.txt(即文件夹及其下文件freezip\free.txt)

////到c:\freezip\free.zip 直接设定为free.zip

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

//// 4

////搬迁压缩c:\freezip\free.txt(即文件夹及其下文件freezip\free.txt)

////到c:\freezip\free.rar 压缩后 原文件将不存在

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

//// 5

////压缩c:\freezip\下的free.txt(即文件free.txt)

////到c:\freezip\free.zip 直接设定为free.zip 只有文件 而没有文件夹

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

//// 6

////解压缩c:\freezip\free.rar

////到 c:\freezip\

//strtxtPath = "c:\\freezip\\";

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

//// 7

////加密压缩c:\freezip\free.txt(即文件夹及其下文件freezip\free.txt)

////到c:\freezip\free.zip 密码为123456 注意参数间不要空格

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

//// 8

////解压缩加密的c:\freezip\free.rar

////到 c:\freezip\ 密码为123456 注意参数间不要空格

//strtxtPath = "c:\\freezip\\";

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

//// 9

////-o+ 覆盖 已经存在的文件

//// -o- 不覆盖 已经存在的文件

//strtxtPath = "c:\\freezip\\";

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

////10

//// 只从指定的zip中

//// 解压出free1.txt

//// 到指定路径下

//// 压缩包中的其他文件 不予解压

//strtxtPath = "c:\\freezip\\";

//Process1.StartInfo.Arguments = " x " + strzipPath + " " +" free1.txt" + " " + strtxtPath;

//// 11

//// 通过 -y 对所有询问回应为"是" 以便 即便发生错误 也不弹出WINRAR的窗口

//// -cl 转换文件名为小写字母

//strtxtPath = "c:\\freezip\\";

//Process1.StartInfo.Arguments = " t -y -cl " + strzipPath + " " + " free1.txt";

Process1.Start();

if (Process1.HasExited)

{

int iExitCode = Process1.ExitCode;

if (iExitCode == 0)

{

Response.Write(iExitCode.ToString() + " 正常完成");

}

else

{

Response.Write(iExitCode.ToString() + " 有错完成");

}

}

}
