Monogame 模板在启动时崩溃，并显示 System.TypeInitializationException

Question

尝试在Windows上运行此程序

#region Using Statements
using System;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Storage;
using Microsoft.Xna.Framework.Input;
#endregion
namespace asdf
{
public class Game1 : Game
{
    GraphicsDeviceManager graphics;
    SpriteBatch spriteBatch;        
    public Game1() //Exception raised points to here
    {
        graphics = new GraphicsDeviceManager(this);
        Content.RootDirectory = "Content";              
        graphics.IsFullScreen = true;       
    }
    protected override void Initialize()
    {
        base.Initialize();
    }
    protected override void LoadContent()
    {
        spriteBatch = new SpriteBatch(GraphicsDevice);
    }
    protected override void Update(GameTime gameTime)
    {
        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
        {
            Exit();
        }       
        base.Update(gameTime);
    }
    protected override void Draw(GameTime gameTime)
    {
        graphics.GraphicsDevice.Clear(Color.CornflowerBlue);
        base.Draw(gameTime);
    }
}
}

引发以下异常

在单声道中运行时。

我试过：

• 重新安装单声道

• 重新安装单游戏

• 重新安装 Xamarin Studio

• 更新窗口

并且错误保持不变。

使用 SFML.Net 代替单游戏时不会发生此错误

完整的解决方案可以在这里找到

Answer 1

修复：

确保 mono 配置文件中没有任何不正确的映射，即删除任何如下所示的行：

<dllmap dll="gdiplus" target="whatever" />
<dllmap dll="gdiplus.dll" target="whatever" />

解释：

如果您查看异常详细信息，您很可能会发现抛出了一个底层System.DllNotFoundException，因为父类Game包含对通过gdiplus.dll公开的System.Drawing.GDIPlus的引用。 gdiplus.dll是一个核心的.NET Framework库，所以它应该已经在GAC中了。无法使用 Mono 等跨平台框架加载此内容的最常见原因是 DLL 映射无效。

Answer 2

这是一个

单声道错误：https://bugzilla.xamarin.com/show_bug.cgi?id=8309

解决方案：在"C：\程序文件 （x86）\Mono-3.2.3\etc\mono\config"中，找到并删除以下行：

<dllmap dll="gdiplus" target="/tmp/install/lib/libgdiplus.so" />
<dllmap dll="gdiplus.dll" target="/tmp/install/lib/libgdiplus.so" />

我可以验证这是否解决了问题。
