使用这个来获得项目目录(为我工作):

string projectPath = 
    Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName;

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

using System;
using System.IO;

// This will get the current WORKING directory (i.e. \bin\Debug)
string workingDirectory = Environment.CurrentDirectory;
// or: Directory.GetCurrentDirectory() gives the same result

// This will get the current PROJECT bin directory (ie ../bin/)
string projectDirectory = Directory.GetParent(workingDirectory).Parent.FullName;

// This will get the current PROJECT directory
string projectDirectory = Directory.GetParent(workingDirectory).Parent.Parent.FullName;

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

使用这个来获得项目目录(为我工作):

string projectPath = 
    Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName;

这还将通过从当前执行目录向上导航两级来为您提供项目目录(这不会为每次构建返回项目目录，但这是最常见的)。

System.IO.Path.GetFullPath(@"..\..\")

当然，您希望将其包含在某种验证/错误处理逻辑中。
