如何在Windows Mobile 3.5中压缩文件？

Question

我正在尝试使用Ionic.Zip.dll的Ionic.Zip.dll压缩文件的方法。

压缩代码：

using Ionic.Zip;
public string Compress(string[] Paths, string SaveFileName, string Password, string CompressionType)
    {
        try
        {
            using (ZipFile zip = new ZipFile())
            {
                if (Password != string.Empty)
                    zip.Password = Password;
                zip.CompressionLevel = Utility.GetCompressionLevel(CompressionType);
                foreach (string item in Paths)
                {
                    if (IsDirectory(item))
                        zip.AddDirectory(item);
                    else if (IsFile(item))
                        zip.AddFile(item);
                }
                zip.Save(SaveFileName);
            }
            return ExplorerResource.ResourceManager.GetString("ZipSuccess");
        }
        catch (Exception ex)
        {
            return ex.Message;
        }
    }  

自定义类：

public class Utility
    {
        public static Ionic.Zlib.CompressionLevel GetCompressionLevel(string Expression)
        {
            Ionic.Zlib.CompressionLevel result = Ionic.Zlib.CompressionLevel.None;
            if (Ionic.Zlib.CompressionLevel.BestCompression.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.BestCompression;
            if (Ionic.Zlib.CompressionLevel.BestSpeed.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.BestSpeed;
            if (Ionic.Zlib.CompressionLevel.Default.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Default;
            if (Ionic.Zlib.CompressionLevel.Level0.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level0;
            if (Ionic.Zlib.CompressionLevel.Level1.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level1;
            if (Ionic.Zlib.CompressionLevel.Level2.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level2;
            if (Ionic.Zlib.CompressionLevel.Level3.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level3;
            if (Ionic.Zlib.CompressionLevel.Level4.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level4;
            if (Ionic.Zlib.CompressionLevel.Level5.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level5;
            if (Ionic.Zlib.CompressionLevel.Level6.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level6;
            if (Ionic.Zlib.CompressionLevel.Level7.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level7;
            if (Ionic.Zlib.CompressionLevel.Level8.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level8;
            if (Ionic.Zlib.CompressionLevel.Level9.ToString().ToUpper() == Expression.Trim().ToUpper())
                result = Ionic.Zlib.CompressionLevel.Level9;

            return result;
        }

ZIP程序的GUI：

但是，当我开始压缩文件时出现此错误。

我认为代码与.net版本不兼容？
我希望有人可以为此解决方案，或者如果您有更好的方法，请告诉我。

Answer 1

您需要至少下载dotnetzip的 1.7版本，然后使用紧凑的框架特定版本（即Ionic.Zip.CF.dll）。

Answer 2

我建议您可以使用Sevenzipsharp，它被7-zip使用，因为它具有良好的性能。 Codeplex上的Sevenzipsharp
