Question

我正在使用JNI4net，虽然安装在构建路径和eclipse中的库识别它们，但它仍然给我运行时错误。你认为为什么会这样？这是代码。

 import net.sf.jni4net.*;

import java.io.IOException;
import java.lang.String;

import system.*;
import system.Object;
import system.io.TextWriter;
import system.collections.IDictionary;
import system.collections.IEnumerator;

    /**
     * @author Pavel Savara (original)
     */
    public class Program {
        public static void main(String[] args) throws IOException {
            // create bridge, with default setup
            // it will lookup jni4net.n.dll next to jni4net.j.jar 
            //Bridge.setVerbose(true);
            Bridge.setVerbose(true);
            Bridge.init();

            // here you go!
            Console.WriteLine("Hello .NET world!\n");

            // OK, simple hello is boring, let's play with System.Environment
            // they are Hashtable realy
            final IDictionary variables = system.Environment.GetEnvironmentVariables();

            // let's enumerate all keys
            final IEnumerator keys = variables.getKeys().GetEnumerator();
            while (keys.MoveNext()) {
                // there hash table is not generic and returns system.Object
                // but we know is should be system.String, so we could cast
                final system.String key = (system.String) keys.getCurrent();
                Console.Write(key);

                // this is automatic conversion of JVM string to system.String
                Console.Write(" : ");

                // we use the hashtable
                Object value = variables.getItem(key);

                // and this is JVM toString() redirected to CLR ToString() method
                String valueToString = value.toString();
                Console.WriteLine(valueToString);
            }

            // Console output is really TextWriter on stream
            final TextWriter writer = Console.getOut();
            writer.Flush();
        }
    }

这是我收到的消息！

为了让您的生活更轻松，我将在此分享我的发现。阅读Martin Serrano对我的问题的回答。它将帮助您了解需要完成的工作。然后转到jni4net的网站并下载他们的示例zip文件夹。提取出来。有一个例子叫myCSharpDemoCalc。用myCSharpDemoCalc.dll（在工作文件夹中）替换你的dll，然后运行generateProxies.cmd（确保将此文件编辑为你的dll名称）和run.cmd。然后转到work文件夹并运行build.cmd（编辑名称）以创建JAR文件。它可能不会吐出j4n.dll你可能需要自己修改路径。使用此JAR文件。这是从我为第三方dll创建JAR文件的最简单方法。
