如果你想知道你的解决方案所在的目录是什么，你需要这样做:

 var parent = Directory.GetParent(Directory.GetCurrentDirectory()).Parent;
            if (parent != null)
            {
                var directoryInfo = parent.Parent;
                string startDirectory = null;
                if (directoryInfo != null)
                {
                    startDirectory = directoryInfo.FullName;
                }
                if (startDirectory != null)
                { /*Do whatever you want "startDirectory" variable*/}
            }

如果你只使用getcurrentdirectory()方法，无论你是在调试还是发布，你都会得到构建文件夹。希望这对你有所帮助!如果你忘记了验证，它会是这样的:

var startDirectory = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.Parent.FullName;

最好的解决方案

string PjFolder1 =
    Directory.GetParent(AppDomain.CurrentDomain.BaseDirectory).
        Parent.Parent.FullName;

其他解决方案

string pjFolder2 = Path.GetDirectoryName(Path.GetDirectoryName(Path.GetDirectoryName(
                System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase)));

测试它，AppDomain.CurrentDomain.BaseDirectory在过去的项目中为我工作，现在我得到调试文件夹....所选的好答案就是不行!

//Project DEBUG folder, but STILL PROJECT FOLDER
string pjDebugFolder = AppDomain.CurrentDomain.BaseDirectory;

//Visual studio folder, NOT PROJECT FOLDER
//This solutions just not work
string vsFolder = Directory.GetCurrentDirectory();
string vsFolder2 = Environment.CurrentDirectory;
string vsFolder3 = Path.GetFullPath(".\\");   

//Current PROJECT FOLDER
string ProjectFolder = 
    //Get Debug Folder object from BaseDirectory ( the same with end slash)
    Directory.GetParent(pjDebugFolder).
    Parent.//Bin Folder object
    Parent. //Project Folder object
    FullName;//Project Folder complete path

Try:

            {
                OpenFileDialog fd = new OpenFileDialog();
                fd.Multiselect = false;
                fd.Filter = "Image files (*.bmp, *.jpg)|*.bmp;*.jpg|All files (*.*)|*.*";
                if (fd.ShowDialog() == true)
                {
                    if (fd.CheckFileExists)
                    {
                        var fileNameToSave = GetTimestamp(DateTime.Now) + Path.GetExtension(fd.FileName);
                        var pathRegex = new Regex(@"\\bin(\\x86|\\x64)?\\(Debug|Release)$", RegexOptions.Compiled);
                        var directory = pathRegex.Replace(Directory.GetCurrentDirectory(), String.Empty);
                        var imagePath = Path.Combine(directory + @"\Uploads\" + fileNameToSave);
                        File.Copy(fd.FileName, imagePath);

                    }
                }
            }
            catch (Exception ex)
            {

                throw ex;
            }

这是上传图片到WPF上传目录的代码

string projPath = Path.GetFullPath(@"..\..\..\");
Console.WriteLine(projPath);

这对我来说一直都很有效。试一试。

这个解决方案很适合我，在开发和测试和PROD服务器上使用ASP。NET MVC5通过c#:

var projectDir = Path.GetDirectoryName(AppDomain.CurrentDomain.BaseDirectory);

如果你需要项目目录中的项目配置文件使用:

$(ProjectDir)

我没有看到使用字符串的解决方案。连接和字符串。Split + SkipLast 4个元素，在这里。

            string projectDir = 
            string.Join('/', AppDomain.CurrentDomain.BaseDirectory
                .Split(new char[] { '/' })
                .SkipLast(4));
