图像到C＃中的字符串文本

I wrote this code

我写了这段代码

MemoryStream ms = new MemoryStream();
pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

Now I want to check ms text. How can I do that?

现在我要查看ms文本。我怎样才能做到这一点？

#1

With this code, you can encode the image Bytes into an hexadecimal string representation:

使用此代码，您可以将图像字节编码为十六进制字符串表示形式：

Byte[] a = ms.ToArray();
String text = BitConverter.ToString(a);

#2

You can try with this code....

您可以尝试使用此代码....

            var url = HostingEnvironment.MapPath("~/Images/" + name);
            byte[] myByte = System.IO.File.ReadAllBytes(url);
           using (MemoryStream ms = new MemoryStream())
            {
                ms.Write(myByte, 0, myByte.Length);
                i = System.Drawing.Image.FromStream(ms);
                System.Drawing.Image imageIn = i.GetThumbnailImage(100, 100,()=> false, IntPtr.Zero);
                imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
                var storedUrl = "data:image;base64," + Convert.ToBase64String(ms.ToArray());
                return storedUrl;
            }

#3

I use this to send the image as string:

我用它来将图像作为字符串发送：

    string path = @"C:\Users\user6\Pictures\wp\tinypotato.jpg";
    string myString = Convert.ToBase64String(File.ReadAllBytes(path))
    Debug.WriteLine(myString); 
...

BR!

BR！
