Image转Base64String

public string ImgToBase64String(string PhotoPath)
            {

                FileStream fs = new FileStream(PhotoPath, FileMode.Open, FileAccess.Read);
                byte[] buffer = new byte[fs.Length];
                fs.Read(buffer, 0, (int)fs.Length);
                string base64String = Convert.ToBase64String(buffer);
                return base64String;
            }

Base64String转Image

public void Base64StringToImage(string strbase64)
            {

                try
                {
                    byte[] arr = Convert.FromBase64String(strbase64);
                    MemoryStream ms = new MemoryStream(arr);
                    System.Drawing.Image img = System.Drawing.Image.FromStream(ms);

                    img.Save($"C://Users//123//Desktop//图片//129.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

                }
                catch (Exception ex)
                {
          System.Console.WriteLine($"出问题了 {ex.Message}");
                }
            }
