c# - 如何在我的 WPF 应用程序中保存图像

Question

在我的 WPF 应用程序中，我无法将图像保存在我的应用程序中的 snap 文件夹中。下面是我正在使用的代码。

OpenFileDialog ofd = new OpenFileDialog();
        ofd.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp"; 
        if (ofd.ShowDialog() == DialogResult.OK)
        {

            string filepath = ofd.FileName;
            File.Copy(ofd.FileName, Application.StartupPath + "\\snaps\\" + ofd.SafeFileName,true);
            photoTextBox.Text= ofd.SafeFileName;
            pictureBox1.Image = Image.FromFile(ofd.FileName);

        }

打开文件浏览器的代码

 string filepath;
        //browse Button
        private void button4_Click(object sender, RoutedEventArgs e)
        {
            OpenFileDialog open = new OpenFileDialog();
            open.Multiselect = false;    
            open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp";
            bool? result = open.ShowDialog();

            if (result == true)
            {
                filepath = open.FileName; // Stores Original Path in Textbox    
                ImageSource imgsource = new BitmapImage(new Uri(filepath)); // Just show The File In Image when we browse It
                Clientimg.Source = imgsource;  
            }
        }

下面是用于保存文件的代码

private static String GetDestinationPath(string filename, string foldername)
        {
            String appStartPath = System.IO.Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName);

            appStartPath = String.Format(appStartPath + "\\{0}\\" + filename, foldername);
            return appStartPath;
        }

如何使用它

string name = System.IO.Path.GetFileName(filepath);
string destinationPath = GetDestinationPath(name,"YourFolderName");

File.Copy(filepath, destinationPath, true);
