描述

We don't support code like this:

someStruct.PointerField += i;
int* x = someStruct.PointerField++;

I'm not sure if it's worth adding support for these constructs -- these are two quite complex features interacting with each other; and such code is quite rare.

研究方向: Investigate the ILSpy codebase to locate where compound assignment expressions are handled. Look at the existing support for pointer arithmetic (e.g., PointerArithmeticInstruction or similar) and see how it handles simple pointer arithmetic without assignment. Then, examine the expression tree or AST nodes for compound assignments (e.g., CompoundAssignmentExpression) to understand how to extend them to support pointer targets. Files likely involved include ICSharpCode.Decompiler/IL/ILInstruction.cs and related visitors. Check the existing tests for pointer arithmetic to ensure no regressions.
