How to compare the picturebox1.image is equal to the image wt I want from imagelist

sir the bellow code may work

MemoryStream imageStream1=new MemoryStream(), imageStream2=new MemoryStream();
Image img1 = pic1.Image;
Image img2 = pic2.Image;
byte[] imageContent1 = new Byte[imageStream1.Length];//Declare a byte array to hold byes read from stream
imageStream1.Position = 0; //set the stream position to start
imageStream1.Read(imageContent1, 0, (int)imageStream1.Length);// load the byte array with the image

byte[] imageContent2 = new Byte[imageStream2.Length];
imageStream2.Position = 0;
imageStream2.Read(imageContent2, 0, (int)imageStream2.Length);
bool equal = true;

if (imageStream1.Length == imageStream2.Length)
for (int i = 0; i < imageContent1.Length; i++)
{
if (imageContent1[i] != imageContent2[i])
{
equal = false;
break;
}
}
else
equal = false;

if (equal)
MessageBox.Show("Equal");
else
MessageBox.Show("Not Equal");
