我开始使用带有 XNA 框架的 C# 编程。我创建了新的解决方案，制作了程序，保存了它。程序正在运行，并且没有错误。在我打开解决方案的第二天，我在一个文件中有很多错误。代码看起来不错，但注释中有错误：

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;
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:
                                                     //Invalid token '(' in class, struct, or interface member declaration, 
                                                     //Invalid token ')' in class, struct, or interface member declaration

        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：

Error   Invalid token '(' in class, struct, or interface member declaration 47  27
Error   Invalid token ')' in class, struct, or interface member declaration 47  36

Error   'The_Destiny_of_Azureus.Hra.ngbutton' is a 'field' but is used like a 'type'    47  28

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这个文件中没有错误。

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关键字对局部变量无效。您要么从类的成员定义中复制并粘贴它，要么只是public错误地添加了。

错误链源于编译器认为您错过了}结束Initialize并且其余支撑被丢弃的事实。

您的同事不可能拥有确切的代码并构建它。

错误是完全正确的。

public有一个局部变量是没有意义的。

因此，编译器假定您试图在类上创建一个字段，但忘记了}.
这会导致更多错误，因为它在错误假设您需要额外的}.
