Answer 1

我试过这个并且它有效

string theFileName = Path.GetFileName(YourFile.FileName);
byte[] thePictureAsBytes = new byte[YourFile.ContentLength];
using (BinaryReader theReader = new BinaryReader(YourFile.InputStream))
                    {
                        thePictureAsBytes = theReader.ReadBytes(YourFile.ContentLength);
                    }
string thePictureDataAsString = Convert.ToBase64String(thePictureAsBytes);
