Delphi Error – E2448 An attribute argument must be a constant expression, typeof expression or array constructor

Delphi Compiler Error

E2448 An attribute argument must be a constant expression, typeof expression or array constructor

Reason for the Error & Solution

The Common Language Runtime specifies that an attribute argument must be a constant expression, a typeof expression or an array creation expression. Attribute arguments cannot be global variables, for example. Attribute instances are constructed at compile-time and incorporated into the assembly metadata, so no run-time information can be used to construct them.
