封装了一个类，方便使用SevenZipSharp，支持加入进度显示事件。
双重加密压缩工具范例：
using SevenZip;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ProcessItems
{

{
//设置库路径
string currentDirectory = AppDomain.CurrentDomain.BaseDirectory;
string dllPath = GetAppropriate7zDllPath(currentDirectory);
if (!File.Exists(dllPath))
{
return false;
}
SevenZipSharpUser.SetSetLibraryPath(dllPath);
return true;
}

{

{

counter++;
}

}
public bool CompressFile(string inputFile, string outputFile, string password = null)
{
try
{
// 检查输入文件是否存在
if (!File.Exists(inputFile))

return true;
}
catch (Exception ex)
{
// 在发生异常时记录日志、抛出异常或返回 false
// 这里简单地返回 false，但你可以根据需要更改此行为
Console.WriteLine($"压缩文件时发生错误: {ex.Message}");
return false;
}
finally
{
}
}
public bool CompressDir(string stInputDir, string stOutputFile, string stPwd)
{

}
使用方法：
//设置库
if (!SevenZipSharpUser.SetSetLibraryPath())
{
MessageBox.Show("7z.dll库引用失败!", "错误！", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
//这里是处理任务逻辑开始========start===========
if (itemInfo.bDoubleCompress)
{
szu.DoubleCompressItem(itemInfo.sItemPath, itemInfo.sDstPath, itemInfo.sPassword1, itemInfo.sPassword2);
}
else
{
szu.CompressItem(itemInfo.sItemPath, itemInfo.sDstPath, itemInfo.sPassword1);
}
//这里是处理任务逻辑结束========end=============
