how we can convert an image into a base64 string and base64 string back to image
In this post I am going show how we can convert Base64 string to Image and base64 string to image. it is very easy in C#.net. using this below code we can do that.
Base64 string

See the out put image of the string.
Sorry it will work good in Firefox

This we can convert into normal image, using this code.
Base64 string to Image
Code:
public Image Base64ToImage(string base64String)
{
// Convert Base64 String to byte[]
{
// Convert Base64 String to byte[]
byte[] imageBytes = Convert.FromBase64String(base64String);
MemoryStream ms = new MemoryStream(imageBytes, 0,
imageBytes.Length);
// Convert byte[] to Image
ms.Write(imageBytes, 0, imageBytes.Length);
Image image = Image.FromStream(ms, true);
return image;
}
Same way we can convert
image to Base64 string
Code:
public string ImageToBase64(Image image,
System.Drawing.Imaging.ImageFormat format)
{
using (MemoryStream ms = new MemoryStream())
{
System.Drawing.Imaging.ImageFormat format)
{
using (MemoryStream ms = new MemoryStream())
{
// Convert Image to byte[]
image.Save(ms, format);
byte[] imageBytes = ms.ToArray();
// Convert byte[] to Base64 String
string base64String = Convert.ToBase64String(imageBytes);
return base64String;
}
}
