我试图在Monogame下运行Visual Studio中构建的项目。它成功构建，但是当我运行它时，我收到以下错误消息：

我找到了这个页面http://www.mono-project.com/docs/advanced/pinvoke/dllnotfoundexception/，但这并没有解决问题。实际上，当我运行ldconfig -p |grep libgdiplus时
我得到了
libgdiplus.so.0 (libc6,x86-64) => /usr/lib/libgdiplus.so.0
libgdiplus.so (libc6,x86-64) => /usr/lib/libgdiplus.so
所以.so文件似乎不是问题（我想，但不确定）。
答案 0 :(得分：0)
我不认为它是重复的，因为如果仔细查看错误消息，它们会有所不同。 Tao.Sdl.dll.config文件存在于/ bin / Debug文件夹中。正如我在http://www.mono-project.com/docs/advanced/pinvoke/dllnotfoundexception/中所建议的那样

实际上，还有更多，但在这里发布时间太长了。另外，正如http://www.mono-project.com/docs/advanced/pinvoke/dllnotfoundexception/中所建议的那样，我查看了/usr/local/lib/libgdiplus.so文件，该文件是libgdiplus.so.0.0.0的链接，但是当我尝试打开时它与gedit或vi一切都是乱七八糟的，即我看到的只是问号和奇怪的字符。有人可以帮帮我吗？
