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

您可以尝试这两种方法中的一种。

string startupPath = System.IO.Directory.GetCurrentDirectory();

string startupPath = Environment.CurrentDirectory;

告诉我，你觉得哪个更好

.Parent.Parent.Parent.Parent.FullName Directory.GetParent (Directory.GetCurrentDirectory ())

会给你项目目录。

基于guucu112的答案，但是对于。net核心控制台/窗口应用程序，它应该是:

string projectDir = 
    Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"..\..\.."));

我在一个xUnit项目中使用这个。net核心窗口应用程序。

我使用以下解决方案来完成这项工作:

string projectDir =
    Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"..\.."));

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
