Question

我正在尝试开发自己的能够编译游戏的MonoGame编辑器。为了做到这一点，我正在尝试通过终端编译游戏以进行测试并确保有可能。在Windows上，它可以正常工作。但是，在MacOS上，我目前无法编译一个简约示例。这是我所拥有的：

我运行的要编译的命令。所有必需的dll /源文件都存在于同一目录中。编译过程本身不会导致任何错误，因此我怀疑问题是否像放错文件一样简单。不过，我确实认为我需要在此处修复某些问题：

csc /reference:MonoGame.Framework.dll /reference:OpenTK.dll /out:MyGame /optimize main.cs

执行命令（这是发生错误的位置。运行该命令后立即打印。）：

mono MyGame

在运行时发生的错误：

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;

namespace MyGame {
    class Program {
        [STAThread]

            for (int i = 0; i < 10000; i++) {

        }

        protected override void Update(GameTime gameTime) {
            if(IsActive) {
                if(GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || 
                    Keyboard.GetState().IsKeyDown(Keys.Escape)) {
                    Exit();
                }

                position.X += 1;
                if(position.X > this.GraphicsDevice.Viewport.Width) {
                    position.X = -100;
                }

                base.Update(gameTime);
            }
        }

        protected override void Draw(GameTime gameTime) {
            GraphicsDevice.Clear(Color.CornflowerBlue);
            spriteBatch.Begin();
            spriteBatch.Draw(texture,position,Color.White);
            spriteBatch.End();
            base.Draw(gameTime);
        }
    }
}
