Error when decoding image C# asp
- by Wayneio
I am trying to use MessagingToolkit to decode an image in C#/ASP. I have managed to encode a qr using this package, but when i try to decode, using the code below it comes up with 2 errors (at the bottom of the page)
I believe this is because I am not getting the image correctly after uploading, but can someone point out exactly where I have gone wrong. Thanks.
protected void CreateCode_OnClick(object sender, EventArgs e)
{
string path = "C:\\Users\\Wayneio\\Documents\\Visual Studio 2012\\Projects\\BAMSystem\\BAMSystem\\";
if (QRUpload.HasFiles == true)
{
FileInfo fi = new FileInfo(QRUpload.FileName);
string extA = fi.Extension;
if (extA == ".jpg" || extA == ".png")
{
QRCodeDecoder decoder = new QRCodeDecoder();
QRUpload.SaveAs(path + QRUpload.FileName);
System.Drawing.Image myImg = System.Drawing.Image.FromFile(path + QRUpload.FileName);
decoder.Decode(myImg);
}
else
{
error.Text = "You have uploaded a " + extA + " file. Please upload either a PNG or a JPG";
}
}
else
{
error.Text = "You have not uploaded an image.";
}
}
Error1:
Error 2 Argument 1: cannot convert from 'System.Drawing.Image' to 'MessagingToolkit.QRCode.Codec.Data.QRCodeImage' c:\users\wayneio\documents\visual studio 2012\Projects\BAMSystem\BAMSystem\default.aspx.cs 38 35 BAMSystem
Error2:
Error 1 The best overloaded method match for 'MessagingToolkit.QRCode.Codec.QRCodeDecoder.Decode(MessagingToolkit.QRCode.Codec.Data.QRCodeImage)' has some invalid arguments c:\users\wayneio\documents\visual studio 2012\Projects\BAMSystem\BAMSystem\default.aspx.cs 38 20 BAMSystem
P.S if anyone has documentation on this MessagingToolkit QR package, it would be useful
