about Regex and List

[redaelyks]

. . .

The question is related to:

DllExport: 1.7.4
Used Visual Studio / MSBuild: vs2017
DllType: netstandard 2

---

my simple DLL with that code:
`using System.Text.RegularExpressions;
using System.Runtime.InteropServices;

namespace ClassLibrary1
{
public class Class1
{
[DllExport]
public static bool example(string hex)
{
return Regex.IsMatch(hex, "[A-Fa-f0-9]{2}");
}

}

}`

JAVA call dll by JNA，but got this：
Exception in thread "main" java.lang.Error: Invalid memory access
at com.sun.jna.Native.invokeInt(Native Method)
at com.sun.jna.Function.invoke(Function.java:418)
at com.sun.jna.Function.invoke(Function.java:361)
at com.sun.jna.Library$Handler.invoke(Library.java:270)
at $Proxy0.example(Unknown Source)
at App.main(App.java:9)
I think the problem is with the regex.What I want to ask is how to use Regex and List?

Hello, Did you try to rebase system object? Did you check the same issue #125 ? In case to inform something new, please add more information as it says in the issue template. Thanks! Personally I don't see the problem for Regex.IsMatch() using netstandard2 I've checked your code quickly via C# ```csharp using dynamic l = new ConariX("ClassLibrary1.dll"); bool r = l.example<bool>("3F"); // OK, returns true ``` but it should be the same for JNA if Compiler.rSysObj=True
