MonoGame，XNA以及FNA在使用中文时比较麻烦，在之前我写过两种方式：

1.资源文件方式使用中文：https://www.xnadevelop.com/ios/use-chinese-in-monogame/

2.预编译xnb方式使用中文：https://www.xnadevelop.com/ios/monogame-character-support-simplification-tool/

下面介绍另一种方式：任意字符生成图片的方式使用中文

注意：本方法使用可在windows下运行

定义Texture2D来存储字符生成的图片

Texture2D textTexture2D;

引用 System.Drawing.dll

在【LoadContent()】方法中将中文字符转换成Texture2D

string str = "使用monogame开发跨平台游戏";
Graphics g = Graphics.FromImage(new Bitmap(1, 1));
Font font = new Font("宋体", 20);
SizeF sizeF = g.MeasureString(str, font); //测量出字体的高度和宽度
Brush brush; //笔刷，颜色
brush = Brushes.Lime;
PointF pf = new PointF(0, 0);
Bitmap img = new Bitmap(Convert.ToInt32(sizeF.Width), Convert.ToInt32(sizeF.Height));
g = Graphics.FromImage(img);
g.DrawString(str, font, brush, pf);

//将字符转换成Texture2D
MemoryStream ms = new MemoryStream();
img.Save(ms, System.Drawing.Imaging.ImageFormat.Png);

textTexture2D=Texture2D.FromStream(graphics.GraphicsDevice, ms);

在【 Draw(GameTime gameTime)】方法中绘制

spriteBatch.Begin();

spriteBatch.Draw(textTexture2D, Vector2.Zero, Microsoft.Xna.Framework.Color.White);
 
spriteBatch.End();

完整代码如下：

            // TODO: Add your drawing code here
            spriteBatch.Begin();

            spriteBatch.Draw(textTexture2D, Vector2.Zero, Microsoft.Xna.Framework.Color.White);
             
            spriteBatch.End();

            base.Draw(gameTime);
        }
    }
}

运行结果：
