Image Conversion And Storing The Image Value Using C#

In this blog, you will learn about image conversion and how to store the image value.

Step 1

First, I wrote class, called ImageConverter.cs, and it has two methods.

First method is converting an image to byte array. 

public Image byteArrayToImage(byte[] byteArrayIn)
{
    MemoryStream ms = new MemoryStream(byteArrayIn);
    Image returnImage = Image.FromStream(ms);
    return returnImage;
}

This method used Image.FromStream to create a method from the memory stream, which creates byte array.

 

Step 2

Now, convert the image into a byte array, using an image convertor class and specify mime type of your png. 

TypeConverter tc = TypeDescriptor.GetConverter(typeof(Byte[]));
Response.ContentType = "image/png"
Response.BinaryWrite((Byte[]) tc.ConvertTo(img, tc));
public static byte[] ImageToBinary(string imagePath)
 {
    FileStream fS = new FileStream(imagePath, FileMode.Open, FileAccess.Read);
    byte[] b = new byte[fS.Length];
    fS.Read(b, 0, (int) fS.Length);
    fS.Close();
    return b;
}
ImageConverter imgCon = new ImageConverter();
return (byte[]) imgCon.ConvertTo(inImg, typeof(byte[]));
string path = Server.MapPath("~/Content/Images/user.png");
byte[] imageByteData = System.IO.File.ReadAllBytes(path);
string imageBase64Data = Convert.ToBase64String(imageByteData);
string imageDataURL = string.Format("data:image/png;base64,{0}", imageBase64Data);
Session["UserProfile"] = imageDataURL;
