这是我的 program.cs 文件（这都是在 VS 2010 上用 C# 完成的） 

    using System;

            /// <summary>
            /// The main entry point for the application.
         /// </summary>
            [STAThread]
         static void Main()
         {
               Application.EnableVisualStyles();

                Application.Run(new Form1());
         }
         static void GameLoop(double elapsedTime)

发生 TypeInitializationException 是因为由于构造函数中发生的另一个异常或由于静态初始化的字段而无法初始化您的类型。

  • 通常 TypeInitializationException 只是另一个实际导致问题的异常的包装器，因此检查内部异常通常会向您显示问题。

  • 如果这不起作用，请尝试从构造函数中注释（或移动代码）以消除这种可能性。

  • 将任何静态字段的初始化移动到函数中并显式调用它们。
