Report
15I made SSRS Report with DP Class.
I need to generate QR Code in this SSRS Report.
So I wrote the code like this two ways.
1.
In this way, it did well before.
But at some point, the error occurred.
So I debugged.
The error occurred at the line "filename = qrCode.GetTempFile("TEST");".
2.
In this way, the error occurred like this.

The error occurred in this line "qrCodeReturn = method.Invoke(qrCodeEncoder, methodArgs);".
The most weird this is that QRCode generating code is working very well in the Job or other Class or Form.
The error occurred in only DP class.
(It did well in Form.)
So I made a Class with QRCode generating codes and called the Class in DP Class.
And the error occured at same point.
So what I have to do?
