copied!<p>This Nugget is super easy to use and works perfectly. <a href="https://www.nuget.org/packages/UnmanagedExports" rel="nofollow">https://www.nuget.org/packages/UnmanagedExports</a></p> <p>You need Visual Studio 2012 (express). Once installed, just add <code>[RGiesecke.DllExport.DllExport]</code> before any static function you want to export. That's it!</p> <p><strong>Example:</strong></p> <p><strong>C#</strong></p> <pre><code>[RGiesecke.DllExport.DllExport] public static int YourFunction(string data) { /*Your code here*/ return 1; } </code></pre> <p><strong>Java</strong></p> <p>Add the import at the top:</p> <pre><code> import com.sun.jna.Native; </code></pre> <p>Add the interface in your class. Its your C# function name preceded by the letter "I":</p> <pre><code> public interface IYourFunction extends com.sun.jna.Library { public int YourFunction(String tStr); }; </code></pre> <p>Call your DLL where you need it in your class:</p> <pre><code>IYourFunction iYourFunction = (IYourFunction )Native.loadLibrary("full or relative path to DLL withouth the .dll extention", IYourFunction.class);//call JNA System.out.println("Returned: " + IYourFunction.YourFunction("some parameter")); </code></pre> <p>EDIT: If the DLL is 32bit, the JDK/JRE has to be 32bit as well. Add the following check to your code:</p> <pre><code>if(!System.getProperty("os.arch").equals("x86")) { throw new Exception(".NET DLL " + "32bits JRE/JDK is required. Currently using " + System.getProperty("os.arch") + ".\r\nTry changing your PATH environement variable."); } </code></pre>
