如何使用C#以编程方式找到我的Dropbox文件夹？*注册表？*环境变量？*等......

Answer 1

更新的解决方案

Dropbox现在提供了一个info.json文件,如下所述:https://www.dropbox.com/en/help/4584

如果您不想处理解析JSON,可以使用以下解决方案:

var infoPath = @"Dropbox\info.json";

var jsonPath = Path.Combine(Environment.GetEnvironmentVariable("LocalAppData"), infoPath);            

if (!File.Exists(jsonPath)) jsonPath = Path.Combine(Environment.GetEnvironmentVariable("AppData"), infoPath);

if (!File.Exists(jsonPath)) throw new Exception("Dropbox could not be found!");

var dropboxPath = File.ReadAllText(jsonPath).Split('\"')[5].Replace(@"\\", @"\");

如果您想解析JSON,可以使用JavaScripSerializer,如下所示:

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();            

var dictionary = (Dictionary < string, object>) serializer.DeserializeObject(File.ReadAllText(jsonPath));

var dropboxPath = (string) ((Dictionary < string, object> )dictionary["personal"])["path"];

弃用解决方案:

您可以阅读dropbox\host.db文件.它是位于AppData\Roaming路径中的Base64文件.用这个:

var dbPath = System.IO.Path.Combine(
                    Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "Dropbox\\host.db");

var dbBase64Text = Convert.FromBase64String(System.IO.File.ReadAllText(dbPath));

var folderPath = System.Text.ASCIIEncoding.ASCII.GetString(dbBase64Text);

希望能帮助到你!

2016年7月更新:由于DROPBOX客户端的更改,下面的代码不再工作,请求接受上述解决方案的答案

Reinaldo的答案本质上是正确的,但它在路径之前提供了一些垃圾输出,因为在host.db文件中似乎有两行,在这种情况下你只想阅读第二行.以下将为您提供路径.

string appDataPath = Environment.GetFolderPath(
                                   Environment.SpecialFolder.ApplicationData);
string dbPath = System.IO.Path.Combine(appDataPath, "Dropbox\\host.db");
string[] lines = System.IO.File.ReadAllLines(dbPath);
byte[] dbBase64Text = Convert.FromBase64String(lines[1]);
string folderPath = System.Text.ASCIIEncoding.ASCII.GetString(dbBase64Text);
Console.WriteLine(folderPath);

Answer 3

基于先前答案的清洁版(使用var,添加存在检查,删除警告):

    private static string GetDropBoxPath()
    {
        var appDataPath = Environment.GetFolderPath(
                                           Environment.SpecialFolder.ApplicationData);
        var dbPath = Path.Combine(appDataPath, "Dropbox\\host.db");

        if (!File.Exists(dbPath))
            return null;

        var lines = File.ReadAllLines(dbPath);
        var dbBase64Text = Convert.FromBase64String(lines[1]);
        var folderPath = Encoding.UTF8.GetString(dbBase64Text);

        return folderPath;
    }

这似乎是Dropbox建议的解决方案:https://www.dropbox.com/help/4584 ？ path = dashtop_client_and_web_app
