Help converting Function to C#

Im a little lost to say the least.

Trying to compare 2 pictureboxes. Are they the same. Thanks

Public Shared Function ImagesAreTheSame(ByVal bmp1 _

As Bitmap, ByVal bmp2 As Bitmap) As Boolean

'If the images aren't the same size, quit

If bmp1.Size.Width <> bmp2.Size.Width OrElse _

bmp1.Size.Height <> bmp2.Size.Height Then

Return False

Else

'Convert each image to a byte array

'.NET.NET()

Dim ic As System.Drawing.ImageConverter = _

New System.Drawing.ImageConverter

Dim btImage1() As Byte = New Byte(1) {}

btImage1 = CType(ic.ConvertTo(bmp1, _

btImage1.GetType()), Byte())

Dim btImage2() As Byte = New Byte(1) {}

btImage2 = CType(ic.ConvertTo(bmp2, _

btImage2.GetType()), Byte())

'The byte arrays may be different lengths if they

'contain different metadata, e.g. EXIF, TIFF tags

If btImage1.Length <> btImage2.Length _

Then Return False

Dim i As Integer

For i = 0 To btImage1.Length - 1

If btImage1(i) <> btImage2(i) Then Return False

Next

Return True

End If

End Function

Is this your whole program Did you define a Main, and a class to hold this function

Probably so. It's typically much easier to use a book/online examples and start from scratch rather than convert a VB.NET program. Converting a program is typically more difficult than writing something basic from scratch.

If you send the errors you're receiving and some other code, I can certainly help out ...

Im very lost....this wont compile...

public Boolean ImagesAreTheSame(Bitmap bmp1, Bitmap bmp2)

{

//If the images aren't the same size, quite

if ((bmp1.Size.Width != bmp2.Size.Width) || (bmp1.Size.Height != bmp2.Size.Height))

{

return false;

}

else

{

//Convert each image to a byte array

//.NET.NET()

System.Drawing.ImageConverter ic = new System.Drawing.ImageConverter();

Byte btImage1 = new Byte(1);

btImage1 = CType(ic.ConvertTo(bmp1, btImage1.GetType()), Byte());

Byte btImage2 = new Byte(1);

btImage2 = CType(ic.ConvertTo(bmp2,btImage2.GetType()), Byte());

if (btImage1.Length != btImage2.Length)

return False;

int i;

for (i = 0; i < btImage1.Length - 1; i++)

if (btImage1(i)!= btImage2(i))

return False;

}

public Boolean ImagesAreTheSame(Bitmap bmp1, Bitmap bmp2)
{
   //If the images aren't the same size, quite
   if ((bmp1.Size.Width <> bmp2.Size.Width) || (bmp1.Size.Height <> bmp2.Size.Height))
   {
      return false;
   }
   else
   {
      //Convert each image to a byte array
      //.NET.NET()
      System.Drawing.ImageConverter ic = new System.Drawing.ImageConverter();
.
.
.
etc.

Follow basic method above for converting rest of your code.

Hope this helps,

Think this works....just converting the calls to c#

private bool CompareBitmaps(Bitmap bmp1, Bitmap bmp2)

{

if ((bmp1.Size.Width != bmp2.Size.Width) || (bmp1.Size.Height != bmp2.Size.Height))

return false;

else

{

System.Drawing.ImageConverter ic = new System.Drawing.ImageConverter();

byte[] btImage1 = new byte[2];

btImage1 = (byte[])ic.ConvertTo(bmp1, btImage1.GetType());

byte[] btImage2 = new byte[2];

btImage2 = (byte[])ic.ConvertTo(bmp2, btImage2.GetType());

if (btImage1.Length != btImage2.Length)

return false;

for (int i = 0; i < btImage1.Length; i++)

if (btImage1 != btImage2)

return false;

return true;

}

}

What errors do you receive ... also, why are you trying to convert the code to C# if you already know VB.NET

Thanks,

trying to learn c#....as far as errors....just about every line.

no constructors, type does'nt exit, byte is a type but used like a variable....on and on.

I figured this was a good example of a "hairy" example to get into....maybe a little much...

Yes...its part of a class
Elisabeth Boonin
private bool CompareBitmaps(Bitmap bmp1, Bitmap bmp2)
{
if (bmp1.Size.Width != bmp2.Size.Width || bmp1.Size.Height != bmp2.Size.Height) {
return false;
} else {
System.Drawing.ImageConverter ic = new System.Drawing.ImageConverter();
byte[][0] btImage1 = new byte[1];
btImage1 = ((byte)(ic.ConvertTo(bmp1, btImage1.GetType())));
byte[][0] btImage2 = new byte[1];
btImage2 = ((byte)(ic.ConvertTo(bmp2, btImage2.GetType())));
if (btImage1.Length != btImage2.Length) {
return false;
}
int i;
for (int i = 0; i <= btImage1.Length - 1; i++) {
if (btImage1(i) != btImage2(i)) {
return false;
}
}
return true;
}
}
