Hi,

I am getting exception "Attempted to read or write protected memory. This is often an indication that other memory is corrupt" when performing specific operation in our application. I am unable to find the root cause or fix the issue.

Please give me some hint where I can fix the issue.

Looking forward to hear from you.

Thanks,

Santosh

this is generally caused by unmanned code. typically classes that access unmanned code or memory implement Dispose().

you will want to learn to do heap analysis. the tools will depend on the runtime version:

Thanks for the response.

However, this did not help much.

Also, I am getting this error after digging the issue deeper:

System.AccessViolationException HResult=0x80004003 Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Source=<Cannot evaluate the exception source> StackTrace: <Cannot evaluate the exception stack trace>

Please let me know if there is any way I can fix this issue

@P Umarani Santosh (SX/EDC1) There are too many possible causes to provide meaningful answers based on guessing.

You should show the code that is resulting in the errors or provide a sample that can reproduce them.
