尝试在 .Net Core 控制台应用程序中使用 System.Drawing 时出错

Question

我正在尝试在 Ubuntu 18.04 上的 .Net Core 控制台应用程序运行中使用 System.Drawing.Common 创建一个位图，但是一旦我执行代码，它就会向我显示:

The type initializer for 'Gdip' threw an exception.
   at System.Drawing.SafeNativeMethods.Gdip.GdipCreateBitmapFromScan0(Int32 width, Int32 height, Int32 stride, Int32 format, HandleRef scan0, IntPtr& bitmap)
   at System.Drawing.Bitmap..ctor(Int32 width, Int32 height, PixelFormat format)
   at MidnightBot.Modules.AdminCommands.CreatePollAsync(String Term1, String Term2, String Description) in /home/MidnightBot/Modules/AdminCommands.cs:line 125
System.DllNotFoundException: Unable to load DLL 'libgdiplus': The specified module could not be found.
   at System.Runtime.InteropServices.FunctionWrapper`1.get_Delegate()
   at System.Drawing.SafeNativeMethods.Gdip.GdiplusStartup(IntPtr& token, StartupInput& input, StartupOutput& output)
   at System.Drawing.SafeNativeMethods.Gdip..cctor()

我也试着按照描述的去做 here。但是没有成功。

感谢您的帮助。

您需要使用包管理器安装 gdiplus 库。例如：

sudo apt-get install libgdiplus
