Hello, guys here is a prototype code:
exAsseblyRef = clr.AddReference("C:\ExamRecordHelper")
from ExamRecordHelper import *
loaderObj = ExamRecordLoader( 'MyBinaryFile.bin') <<<<<< Exception here.
On the 3d line the C# constructor ExamRecordLoader(String) is called - it can't create the object.
The actual exception is: "Column requires a valid DataType."
However, the same binary file used with native C# code: ExamRecordLoader( 'MyBinaryFile.bin') works with no errors.
Obviously something is happening when the binary file is being used by the C# class...
