返回具有不同值的多个阵列

Question

如何返回具有不同值的多个阵列？在我的第一个函数中，我得到了我的文件夹中的所有文件。

在我的第二个函数中，我为每个文件提取“modDesc.xml”并从中获取我的信息。现在我想为每个文件返回包含所有这些信息的数组！但我不知道如何......我希望有人能帮助我！

这里是我的代码：

public string[] openDirectory(string DirectoryPath) 
{ 
    string[] files = Directory.GetFiles(DirectoryPath, "*.zip"); 

    return files; 
} 

public string[] getModDesc(string DirectoryPath) 
{ 
    string[] files = openDirectory(DirectoryPath); 

    foreach (var file in files) 
    { 
     using (ZipFile zip = ZipFile.Read(file)) 
     { 
      ZipEntry modDescHandler = zip["modDesc.xml"]; 

      if (modDescHandler != null) 
      { 
       if (File.Exists("tmp\\modDesc.xml")) 
       { 
        File.Delete("tmp\\modDesc.xml"); 
       } 

       modDescHandler.Extract("tmp"); 

       XDocument modDesc = XDocument.Load("tmp\\modDesc.xml"); 
       string modTitle = null; 
       string modAuthor = null; 
       string modVersion = null; 
       string modFileName = null; 

       try 
       { 
        modTitle = modDesc.Element("modDesc").Element("title").Element("de").Value; 
        modAuthor = modDesc.Element("modDesc").Element("author").Value; 
        modVersion = modDesc.Element("modDesc").Element("version").Value; 
       } 

       catch 
       { 

       } 

       modFileName = Path.GetFileName(file); 

       string[] modInformation = { modTitle, modAuthor, modVersion, modFileName }; 

       File.Delete("tmp\\modDesc.xml"); 

       return modInformation; 

      } 
     } 
    } 

    return new string[0]; 
}

你可以返回一个List<string[]>（阵列即列表），其中将包括您的阵列收集的每个文件：

public List<string[]> getModDesc(string DirectoryPath) 
{ 
     // Create a list to store your arrays 
     List<string[]> fileInformation = new List<string[]>(); 

     // Get your files 
     string[] files = openDirectory(DirectoryPath); 
     foreach (var file in files) 
     { 
       using (ZipFile zip = ZipFile.Read(file)) 
       { 
        // All your code (omitted for brevity) 

        // Create your array for this file 
        string[] modInformation = { modTitle, modAuthor, modVersion, modFileName }; 

        // Add this to your list 
        fileInformation.Add(modInformation); 
       } 
     } 
     // At this point your arrays collection should have all of your 
     // arrays, so return it 
     return fileInformation; 
    } 
} 

或者如果你的文件名是每个唯一的，你想要ED使访问它们更容易一点，你可以将它们存储在一个字典，它会让你通过它的名称来查找每一个高达：

public Dictionary<string,string[]> getModDesc(string DirectoryPath) 
{ 
    // Create a list to store your arrays 
    Dictionary<string,string[]> fileInformation = new Dictionary<string,string[]>(); 

    // Get your files 
    string[] files = openDirectory(DirectoryPath); 
    foreach (var file in files) 
    { 
      using (ZipFile zip = ZipFile.Read(file)) 
      { 
       // All your code (omitted for brevity) 

       // Create your array for this file 
       string[] modInformation = { modTitle, modAuthor, modVersion, modFileName }; 

       // Add this to your dictionary, mapping the file name 
       // to it's information 
       fileInformation.Add(modFileName,modInformation); 
      } 
    } 
    // At this point your dictionary should have all of your 
    // arrays, so return it 
    return fileInformation; 
} 

}

然后，如果你想访问信息从字典中的文件中，您可以简单地使用：

string[] information = yourDictionary["YourFileName"];
