Conversion Error

Its not a string though - use BinaryReader.

You can just use Image.FromFile though (although be warned
that this has the side effect of not closing the file)

I'm reading the file in out of my hard drive.  I think run
the
ConvertStringToByteArray which converts it to a Byte[].  I
then try to
convert the Byte[] into the image.

StreamReader sr = new StreamReader(outFilePathAndName);
convertedImage = ConvertStringToByteArray(sr.ReadToEnd());

public static Byte[] ConvertStringToByteArray(string
stringToConvert)
{
     return (new
UnicodeEncoding()).GetBytes(stringToConvert);
}

Is this byte array coming from a database table?  (e.g. an
Image column)?

I'm trying to convert a System.Byte[] into
System.Drawing.Image.  I've
included my code below.  When I execute
System.Drawing.Image.FromStream(ms)
I get the following error: System.ArgumentException: 
Parameter is not
valid.  Does anyone have an idea as to why this is throwing
an error?



public System.Drawing.Image ByteArrayToImage(Byte[]
byteArrayIn)

{

    MemoryStream ms = new MemoryStream(byteArrayIn);

    System.Drawing.Image returnImage =
System.Drawing.Image.FromStream(ms);

    return returnImage;

}



Thanks,
