CA2101 Warning when making extern calls

Question

I\'m using the WinPcap libraries and have set up all my native method calls. Upon building I get the CA2101: Specify marshaling for P/Invoke string arguments Code Analysis

Answer 1

This warning occurs because truncating Unicode text to an ASCII string can cause security issues.

If you cannot use Unicode strings, set BestFitMapping = false, ThrowOnUnmappableChar = true on the attribute to prevent this security issue. For more information, see the documentation.
