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)

试试这个，很简单

HttpContext.Current.Server.MapPath("~/FolderName/");

我也在找这个。我有一个运行HWC的项目，我想让网站远离应用程序树，但我不想让它在调试(或发布)目录。FWIW是公认的解决方案(这个也是)，它只标识可执行文件所在的目录。

找到我一直在用的那个目录

string startupPath = System.IO.Path.GetFullPath(".\\").

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
