求大神指点，怎么用JNA调用dll，出错如下：
java代码：public class WordUtils {
public interface Dll extends StdCallLibrary {
Dll INSTANCE = (Dll) Native.loadLibrary("HtmlToWordDll", Dll.class);//加载动态库文件
public int runTest(String s);//动态库中调用的方法
}
public static void main(String[] args) {
System.out.println(Dll.INSTANCE.runTest("love"));
}
c#类库代码：namespace HtmlToWordDll
{
public class Class1
{
public static void runTest(string basePath)
{
Console.WriteLine("小源很帅：" + basePath);
}
}
}
java报错信息：
Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'runTest': 找不到指定的程序。
