昨天又看了下，发现如果路径中有空格（如：D:\Program Files\）的话压缩解压就会出现问题，折磨了我很长时间，最后实在没办法了就在cmd里面试了半天，发现在有空格的路径上加双引号就可以了。在代码里Directory.CreateDirectory(path);后面把 path 和 rarName 都判断一下如果有空格，就加上 path = “\”" + path + “\”";

  c#与RAR 收藏
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”);
                }

C#调用rar.exe解压一个rar文件到系统的临时目录

//C#调用rar.exe解压一个rar文件到系统的临时目录： //取得系统临时目录 string sysTempDir = Path.GetTempPath();   //要解压的文件路径，请自行设置 string rarFilePath = @”d:\test.rar”; //确定要解压到的目录，是系统临时文件夹下，与原压缩文件同名的目录里 string unrarDestPath = Path.Combine(sysTempDir,     Path.GetFileNameWithoutExtension(rarFilePath)); //组合出需要shell的完整格式 string shellArguments = string.Format(“x -o+ \”{0}\” \”{1}\\\”",     rarFilePath, unrarDestPath); //用Process调用 using (Process unrar = new Process()) {     unrar.StartInfo.FileName = “rar.exe”;     unrar.StartInfo.Arguments = shellArguments;     //隐藏rar本身的窗口     unrar.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;     unrar.Start();     //等待解压完成     unrar.WaitForExit();     unrar.Close(); } //统计解压后的目录和文件数 DirectoryInfo di = new DirectoryInfo(unrarDestPath); MessageBox.Show(string.Format(“解压完成，共解压出：{0}个目录，{1}个文件”,     di.GetDirectories().Length, di.GetFiles().Length));
