i need to add barcode pic to Barcodemat column in crpReport like this

r["BarcodeMat"] = ImageToByte2(bar.Encode(typebq, data, w, hh));

and this is my function ImageToByte2

 private byte[] ImageToByte2(object img)
{
    byte[] byteArray = new byte[1];
    using (MemoryStream stream = new MemoryStream())
    {
        img.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
        stream.Close();
        byteArray = stream.ToArray();
    }
    return byteArray;
}

i have error in

img.Save(stream, System.Drawing.Imaging.ImageFormat.Png);

The error said 'object' does not contain a definition for 'Save' and no extension method 'Save' accepting first argument of type 'object' could be found

CodePudding user response：

From barnhill/barcodelib Barcode (Line 336),

public Image Encode(TYPE iType, string StringToEncode, int Width, int Height)

The method is returned with Image type.

Hence, change img parameter to Image type.

using System.Drawing;

private byte[] ImageToByte2(Image img)
{
    ...
}
