要将图像保存到本地驱动器，可以使用给定命令
将IO命名空间导入为

To save image to local drive you can use given command
import IO namespace as

using System.IO;

然后使用给定的代码

and then use given code

SaveFileDialog obj = new SaveFileDialog();
          obj.Filter = "JPeg Image|*.jpg|Bitmap Image|*.bmp|Gif Image|*.gif";
          obj.Title = "Save your Image File";
          obj.ShowDialog();
          if (obj.FileName != "")
         {
             FileStream fs = (FileStream)obj.OpenFile();
             switch (obj.FilterIndex)
             {
                 case 1 : this.pictureBox1.Image.Save(fs, System.Drawing.Imaging.ImageFormat.Jpeg);
                     break;
                 case 2 : this.pictureBox1.Image.Save(fs, System.Drawing.Imaging.ImageFormat.Bmp);
                     break;
                 case 3 : this.pictureBox1.Image.Save(fs, System.Drawing.Imaging.ImageFormat.Gif);
                     break;
