各位大侠帮忙看看我的jni的这个异常是怎么回事。

Question

我正在做一个jni调用c＃，先是一个cpp调用c＃，再用jni调那个cpp，但运行就抛出一个异常，代码如下：
c＃：
using System;
public class Class1
{public Class1(){};
public void Display(){Console.WriteLine("Hello from c# console");}}
cpp:
#using <mscorlib.dll>
#using "Class1.netmodule"
#using namespace System;
__gc class HelloWorldC {
public:
Class1 __gc *t;
HelloWorldC() {
t = new Class1();
}
void method() {
t -> Display();
}};
jni:
#include <jni.h>
#include "HelloWorld.h"
#include <stdio.h>
#include <windows.h>
#include "HelloWorld.cpp"
#using "helloWorld.dll"
JNIEXPORT void JNICALL Java_HelloWorld_displayHelloWorld(JNIEnv *env, jobject obj) 
{   printf("Helloaa world!\n");
    HelloWorldC* t = new HelloWorldC();
    t->method();
    return;}
java:
class HelloWorld {
    public native void displayHelloWorld();
    static {
     System.loadLibrary("hello");
    }
    public static void main(String[] args) {
        new HelloWorld().displayHelloWorld();
    }}
