我想将文件夹压缩为扩展名为.7z的文件,使用7zip。

我想知道我会怎么做,因为我不确定(这就是我要问的原因。)

这是在C#中。

使用7zip压缩或解压缩文件的代码

此代码用于压缩文件夹

  public void CreateZipFolder(string sourceName, string targetName)
        {
            // this code use for zip a folder
             sourceName = @"d:\Data Files"; // folder to be zip
             targetName = @"d:\Data Files.zip"; // zip name you can change 
            ProcessStartInfo p = new ProcessStartInfo();
            p.FileName = @"D:\7-Zip\7z.exe";
            p.Arguments = "a -t7z \"" + targetName + "\" \"" + sourceName + "\" -mx=9";
            p.WindowStyle = ProcessWindowStyle.Hidden;
            Process x = Process.Start(p);
            x.WaitForExit();
        }

此代码用于压缩文件

 public void CreateZip(string sourceName, string targetName)
        {
            // file name to be zip , you must provide file name with extension
             sourceName = @"d:\ipmsg.log";
             // targeted file , you can change file name 
             targetName = @"d:\ipmsg.zip"; 

            ProcessStartInfo p = new ProcessStartInfo();
            p.FileName = @"D:\7-Zip\7z.exe";
            p.Arguments = "a -tgzip \"" + targetName + "\" \"" + sourceName + "\" -mx=9";
            p.WindowStyle = ProcessWindowStyle.Hidden;
            Process x = Process.Start(p);
            x.WaitForExit();

        }

此代码用于解压缩

 public void ExtractFile(string source, string destination)
        {
            // If the directory doesn't exist, create it.
            if (!Directory.Exists(destination))
                Directory.CreateDirectory(destination);

            string zPath = @"D:\7-Zip\7zG.exe";
            try
            {
                ProcessStartInfo pro = new ProcessStartInfo();
                pro.WindowStyle = ProcessWindowStyle.Hidden;
                pro.FileName = zPath;
                pro.Arguments = "x \"" + source + "\" -o" + destination;
                Process x = Process.Start(pro);
                x.WaitForExit();
            }
            catch (System.Exception Ex) { }
        }

我同意这是重复的,但我之前使用过此代码项目中的演示,它非常有帮助:

这里fileDirPath是我的文件夹的路径,它包含我的所有文件,preferredPath是我想要的.zip文件的路径。

例如:     var fileDirePath = @“C:\ Temp”;     var prefferedPath = @“C:\ Output \ results.zip”;

private void CreateZipFile(string fileDirPath, string prefferedPath)
    {
        ProcessStartInfo p = new ProcessStartInfo();
        p.FileName = @"C:\Program Files\7-Zip\7z.exe";
        p.Arguments = "a \"" + prefferedPath + "\" \"" + fileDirPath + "\"";
        p.WindowStyle = ProcessWindowStyle.Hidden;
        Process x = Process.Start(p);
        x.WaitForExit();
        return;
    }
