我是MVC的新手,我的问题是我没有以正确的方式解决这个问题,它目前的工作方式我的预期,但我不确定结构以及放置方法的位置。
我有一个类用于帮助显示视图(视图模型?),名为FolderFileList
,它还包含一个名为GetFolderStructure()
的函数,该函数采用路径和文件夹并循环创建所有文件和文件夹的列表,然后返回它们。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
namespace xxx.Models
{
public class FolderFileList
{
public DirectoryInfo Directory { get; set; }
public FileInfo File { get; set; }
public List<FileInfo> FileList { get; set; }
public List<DirectoryInfo> FolderList { get; set; }
public List<DirectoryInfo> RootFolderList { get; set; }
public string FolderRoot { get; set;
}
public static FolderFileList GetFolderStructure(string path, string foldername)
{
//initialise variables
DirectoryInfo selecteddirectory = null;
DirectoryInfo rootdirectory = null;
var files = new List<FileInfo>();
var listoffilesandfolders = new FolderFileList();
listoffilesandfolders.FileList = new List<FileInfo>();
listoffilesandfolders.FolderList = new List<DirectoryInfo>();
listoffilesandfolders.RootFolderList = new List<DirectoryInfo>();
listoffilesandfolders.FolderRoot = foldername;
//get selected directory
try
{
selecteddirectory = new DirectoryInfo(path + foldername);
listoffilesandfolders.FolderList = selecteddirectory.GetDirectories("*", SearchOption.AllDirectories).ToList();
}
catch (DirectoryNotFoundException exp)
{
throw new Exception("Could not open the directory", exp);
}
catch (IOException exp)
{
throw new Exception("Failed to access directory", exp);
}
//get root directory
try
{
rootdirectory = new DirectoryInfo(path);
listoffilesandfolders.RootFolderList = rootdirectory.GetDirectories("*", SearchOption.TopDirectoryOnly).ToList();
}
catch (DirectoryNotFoundException exp)
{
throw new Exception("Could not open the directory", exp);
}
catch (IOException exp)
{
throw new Exception("Failed to access directory", exp);
}
//get all files and subfolder files
try
{
files = selecteddirectory.GetFiles("*", SearchOption.AllDirectories).ToList();
}
catch (FileNotFoundException exp)
{
throw new Exception("Could not find file", exp);
}
catch (IOException exp)
{
throw new Exception("Failed to access fie", exp);
}
files = files.OrderBy(f => f.Name).ToList();
foreach (FileInfo file in files)
{
listoffilesandfolders.FileList.Add(file);
}
return listoffilesandfolders;
}
}
我的控制器:
public ActionResult Folder(string foldername)
{
var path = Server.MapPath(@"~\");
var folderstructure = FolderFileList.GetFolderStructure(path, foldername);
return View(folderstructure);
}
我的问题是:
答案 0 :(得分:0)
回答第一个问题:
就个人而言,我会创建一个名为“ViewModels”或“Classes”的文件夹。这完全取决于你。如果移动类,则应更新代码中的命名空间。
编号2:您可以在ViewModel中存放该方法。正如StewartLC下面提到的那样,视图可以调用该方法,您可能不希望这样。如果没有,我会把它放在控制器中。
