FileStream не откроет устройства Win32, такие как дисковые разделы и ленточные накопители. (DotNetZip)

Question

Я пытаюсь использовать DotNetZip обрабатывать почтовые файлы, но всякий раз, когда я пытаюсь открыть файл, я получаю следующее сообщение об ошибке:

[SEVERE] System.ArgumentException: FileStream will not open Win32 devices such as disk partitions and tape drives. Avoid use of "\\.\" in the path.

at ModsInstaller.Form1.btn_install_Click(Object sender, EventArgs e) in C:\Users\Admin\documents\visual studio 2010\Projects\ModsInstaller\ModsInstaller\Form1.cs:line 120 

и вот код:

private void MergeDirectories(string Path1, string Path2) 
    { 
     string outDirectory = Path.GetFullPath(workspace + "\\temp\\dir"); 

     if (!Directory.Exists(outDirectory)) 
      Directory.CreateDirectory(outDirectory); 

     Path1 = Path.GetFullPath(Path1); 
     Path2 = Path.GetFullPath(Path2);    

     Log("Extracting {0} to temp dir.", Path1); 
     using (ZipFile zip = ZipFile.Read(Path1)) 
     { 
      zip.ExtractAll(outDirectory); //this line throws the error 
     } 
     Log("Extraction sucessfull"); 

     Log("Extracted {0} to temp dir.", Path2); 
     ZipFile.Read(Path2).ExtractAll(Path.GetFullPath(workspace + "\\temp\\dir")); 
     Log("Extraction sucessfull"); 

     ZipFile z = new ZipFile(workspace + "\\temp\\build.jar"); 
     z.AddDirectory(workspace + "\\temp\\dir"); 
     z.Save(); 
     z.Dispose(); 
    } 

и когда я вставляю точку останова, я вижу следующее:

outDirectory = "C:\\Users\\Admin\\documents\\visual studio 2010\\Projects\\ModsInstaller\\ModsInstaller\\bin\\Debug\\temp\\dir" 

Может ли кто-нибудь указать, что я делаю неправильно?

Спасибо.

Использование

MergeDirectories("Sample 1.zip", "Sample 2.zip", "Merged.zip"); 

Код:

private void MergeDirectories(string filePath1, string filePath2, string mergedName) 
    { 
     string workspace = Environment.CurrentDirectory; 
     filePath1 = Path.Combine(workspace, filePath1); 
     filePath2 = Path.Combine(workspace, filePath2); 
     mergedName = Path.Combine(workspace, mergedName); 

     if (File.Exists(mergedName)) 
     { 
      File.Delete(mergedName); 
     } 

     DirectoryInfo zip1 = OpenAndExtract(filePath1); 
     DirectoryInfo zip2 = OpenAndExtract(filePath2); 

     string merged = Path.GetTempFileName(); 
     using (ZipFile z = new ZipFile()) 
     { 
      z.AddDirectory(zip1.FullName); 
      z.AddDirectory(zip2.FullName); 
      z.Save(merged); 
     } 

     zip1.Delete(true); 
     zip2.Delete(true); 

     File.Move(merged, mergedName); 
    } 

    private DirectoryInfo OpenAndExtract(string path) 
    { 
     string tmpName = Path.GetFileNameWithoutExtension(Path.GetRandomFileName()); 
     string tmp = Path.Combine(Path.GetTempPath(), tmpName); 

     FileInfo sourcePath = new FileInfo(path); 
     DirectoryInfo tempPath = Directory.CreateDirectory(tmp); 

     using (ZipFile zip = ZipFile.Read(sourcePath.FullName)) 
     { 
      zip.ExtractAll(tempPath.FullName); 
     } 

     return tempPath; 
    }
