我正在尝试制作一个 Jni4net 程序来充当 Java 数据库和 C# 应用程序之间的桥梁。在做了一些 Jni4net 附带的示例之后，我尝试按照本指南进行操作。在他的程序运行时彻底遵循它之后，我得到了错误：
System.IO.FileNotFoundException
我用代码尝试了不同的东西几个小时，但没有进展。这是代码，我认为我的方法没有任何问题，文件TestOne.j4n.dll确实在 location 下FourthTest/TestOne.j4n.dll。这是Bridge.LoadAndRegisterAssemblyFrom给我错误的方法。
import java.io.File;
import java.io.IOException;
import net.sf.jni4net.Bridge;
public class WriteHejsan {
public static void main(String[] args) throws IOException{
try{
Bridge.setVerbose(true);
Bridge.init();
Bridge.setDebug(true);
// File proxyAssemblyFile = new File("TestOne.j4n.dll");
// Bridge.LoadAndRegisterAssemblyFrom(proxyAssemblyFile);
// Bridge.LoadAndRegisterAssemblyFrom(new java.io.File("C:/Users/Nikolai/JNIworkspace/FourthTest/TestOne.j4n.dll"));
Bridge.LoadAndRegisterAssemblyFrom(new java.io.File("TestOne.j4n.dll"));
// testone.TestClass.Name();
}
catch(Exception e){
e.printStackTrace();
}
}
}
编辑：
我得到的完整错误消息是（瑞典语中的某些部分）
