Visual C#Express中的无意义错误

Question

我开始使用XNA框架在C#中编程.我创建了新的解决方案,制作了程序,保存了它.程序正在工作,没有错误.在我打开解决方案的第二天,我在一个文件中遇到了很多错误.代码似乎没问题,这里的评论中有错误:

using Microsoft.Xna.Framework.GamerServices;

using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Media;
using The_Destiny_of_Azureus.Komponenty;

namespace The_Destiny_of_Azureus
{

public class Hra : Microsoft.Xna.Framework.Game
{
    GraphicsDeviceManager graphics;
    public SpriteBatch spriteBatch;

    public int wwidth = 1366;
    public int wheight = 768;

    Texture2D cursor;

    MouseState mouseState;

    public Hra()
    {
        graphics = new GraphicsDeviceManager(this);
        Content.RootDirectory = "Content";
    }


    protected override void Initialize()
    {
        graphics.PreferredBackBufferWidth = wwidth;
        graphics.PreferredBackBufferHeight = wheight;
        graphics.IsFullScreen = false;
        graphics.ApplyChanges();

        MMenu mmenu = new MMenu(this);
        Components.Add(mmenu);           //1 error: } expected


        public Button ngbutton = new Button(this, new Vector2(64, 258), "NEW GAME");     // Keyword 'this' is not available in the current context
        Components.Add(ngbutton);       //3 errors:

        base.Initialize();                       //1 error: Method must have a return type
    }


    protected override void LoadContent()     //1 error: Expected class, delegate, enum, interface, or struct
    {

        spriteBatch = new SpriteBatch(GraphicsDevice);      //1 error: Expected class, delegate, enum, interface, or struct

        cursor = Content.Load<Texture2D>(@"Textury\cursor");
    }


    protected override void UnloadContent()            //1 error: Expected class, delegate, enum, interface, or struct
    {

    }


    protected override void Update(GameTime gameTime)        //1 error: Expected class, delegate, enum, interface, or struct
    {

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
            this.Exit();


        mouseState = Mouse.GetState();

        base.Update(gameTime);
    }


    protected override void Draw(GameTime gameTime)           //1 error: Expected class, delegate, enum, interface, or struct
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        spriteBatch.Begin();
        spriteBatch.Draw(cursor, new Vector2(mouseState.X, mouseState.Y), Color.White);      //1 chyba: Expected class, delegate, enum, interface, or struct
        spriteBatch.End(); 

        base.Draw(gameTime);
    }              //1 error: Type or namespace definition, or end-of-file expected
}
}

错误:

我尝试将整个解决方案发送给我的朋友,他打开了解决方案并且他在此文件中没有错误.

你的问题在这里:

Components.Add(mmenu);           //1 error: } expected


public Button ngbutton = new Button(this, new Vector2(64, 258), "NEW GAME");     // Keyword 'this' is not available in the current context
Components.Add(ngbutton);       //3 errors:

该public关键字是无效的局部变量.您要么从类中的成员定义复制并粘贴它,要么只是public错误添加.

错误链源于这样一个事实:编译器认为你错过了一个}结束Initialize而其余的支撑被抛弃了.

你的同事没有办法拥有那些确切的代码并且无法构建它.
