這篇文章主要介紹了C#調(diào)用7z實(shí)現(xiàn)文件的壓縮與解壓，幫助大家更好的理解和使用c#，感興趣的朋友可以了解下

1.關(guān)于7z

首先在這里先介紹一下7z壓縮軟件，7z是一種主流的壓縮格式，它擁有極高的壓縮比。在計(jì)算機(jī)科學(xué)中，7z是一種可以使用多種壓縮算法進(jìn)行數(shù)據(jù)壓縮的檔案格式。主要有以下特點(diǎn)：

來源且模塊化的組件結(jié)構(gòu)
最高的壓縮比
強(qiáng)大的AES-256加密
可更改配置的壓縮算法
支持操大文件
支持多線程壓縮
具有多種壓縮文件格式

2.解壓縮實(shí)現(xiàn)代碼

實(shí)現(xiàn)對(duì)文件的解壓縮方法是通過cmd命令，調(diào)用7z程式通過cmd命令實(shí)現(xiàn)對(duì)文件進(jìn)行解壓和壓縮的操作，具體實(shí)現(xiàn)代碼如下：

壓縮代碼

壓縮的cmd命令："7Z a -tzip " + zipPath + " " + filePath;

public ExecutionResult CompressFile(string filePath, string zipPath)//運(yùn)行DOS命令
    {
      ExecutionResult exeRes = new ExecutionResult();
      exeRes.Status = true;
      try
      {
        Process process = new Process();
        process.StartInfo.FileName = "cmd.exe";
        string message = "";
        string command1 = "c:";
        string command2 = @"cd\";
        string command3 = @"cd C:\Progra~1\7-Zip";
        string command4 = "";


        command4 = "7Z a -tzip " + zipPath + " " + filePath;

        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardInput = true;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.RedirectStandardError = true;
        process.StartInfo.CreateNoWindow = true;
        process.Start();
        process.StandardInput.WriteLine(command1);
        process.StandardInput.WriteLine(command2);
        process.StandardInput.WriteLine(command3);
        process.StandardInput.WriteLine(command4);
        process.StandardInput.WriteLine("exit");
        message = process.StandardOutput.ReadToEnd(); //要等壓縮完成后才可以來抓取這個(gè)壓縮文件

        process.Close();
        if (!message.Contains("Everything is Ok"))
        {
          exeRes.Status = false;
          exeRes.Message = message;
        }
        else
        {
          exeRes.Anything = zipPath;
        }
      }
      catch (Exception ex)
      {
        exeRes.Message = ex.Message;
      }

      return exeRes;
    }

解壓代碼

解壓的cmd命令："7Z x -tzip " + zipPath + " -o" + filePath + " -y";

public ExecutionResult DeCompressFile( string zipPath, string filePath)//運(yùn)行DOS命令
    {
      ExecutionResult exeRes = new ExecutionResult();
      exeRes.Status = true;
      try
      {
        Process process = new Process();
        process.StartInfo.FileName = "cmd.exe";
        string message = "";
        string command1 = "c:";
        string command2 = @"cd\";
        string command3 = @"cd C:\Progra~1\7-Zip";
        string command4 = "";


        command4 = "7Z x -tzip " + zipPath + " -o" + filePath + " -y";

        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardInput = true;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.RedirectStandardError = true;
        process.StartInfo.CreateNoWindow = true;
        process.Start();
        process.StandardInput.WriteLine(command1);
        process.StandardInput.WriteLine(command2);
        process.StandardInput.WriteLine(command3);
        process.StandardInput.WriteLine(command4);
        process.StandardInput.WriteLine("exit");
        //process.WaitForExit();
        message = process.StandardOutput.ReadToEnd();//要等壓縮完成后才可以來抓取這個(gè)壓縮文件

        process.Close();
        if (!message.Contains("Everything is Ok"))
        {
          exeRes.Status = false;
          exeRes.Message = message;
        }
        else
        {
          exeRes.Anything = filePath;
        }
      }
      catch (Exception ex)
      {
        exeRes.Message = ex.Message;
      }

      return exeRes;
    }
