ContentLoadException in MonoGame

Question

我一直在尝试使用Xamarin在MonoGame中加载纹理。我的代码设置如下：

#region Using Statements
using System;

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

#endregion

namespace TestGame
{
    /// <summary>
    /// This is the main type for your game
    /// </summary>
    public class Game1 : Game
    {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;

        //Game World
        Texture2D texture;
        Vector2 position = new Vector2(0,0);

        public Game1 ()
        {
            graphics = new GraphicsDeviceManager (this);
            Content.RootDirectory = "Content";              
            graphics.IsFullScreen = false;      
        }

        /// <summary>
        /// Allows the game to perform any initialization it needs to before starting to run.
        /// This is where it can query for any required services and load any non-graphic
        /// related content.  Calling base.Initialize will enumerate through any components
        /// and initialize them as well.
        /// </summary>
        protected override void Initialize ()
        {
            // TODO: Add your initialization logic here
            base.Initialize ();

        }

        /// <summary>
        /// LoadContent will be called once per game and is the place to load
        /// all of your content.
        /// </summary>
        protected override void LoadContent ()
        {
            // Create a new SpriteBatch, which can be used to draw textures.
            spriteBatch = new SpriteBatch (GraphicsDevice);

            //Content
            texture = Content.Load<Texture2D>("player");
        }

        /// <summary>
        /// Allows the game to run logic such as updating the world,
        /// checking for collisions, gathering input, and playing audio.
        /// </summary>
        /// <param name="gameTime">Provides a snapshot of timing values.</param>
        protected override void Update (GameTime gameTime)
        {
            // For Mobile devices, this logic will close the Game when the Back button is pressed
            if (GamePad.GetState (PlayerIndex.One).Buttons.Back == ButtonState.Pressed) {
                Exit ();
            }
            // TODO: Add your update logic here         
            base.Update (gameTime);
        }

        /// <summary>
        /// This is called when the game should draw itself.
        /// </summary>
        /// <param name="gameTime">Provides a snapshot of timing values.</param>
        protected override void Draw (GameTime gameTime)
        {
            graphics.GraphicsDevice.Clear (Color.CornflowerBlue);

            //Draw

            spriteBatch.Begin ();
            spriteBatch.Draw (texture, position, Color.White);
            spriteBatch.End ();

            base.Draw (gameTime);
        }
    }
}

当我调试它时，它会给出错误：

Microsoft.Xna.Framework.Content.ContentLoadException:无法将播放器资产加载为非内容文件！-> Microsoft.Xna.Framework.Content.ContentLoadException:目录未找到。-> System.IO.DirectoryNotFoundException:找不到路径的一部分-> System.Exception： -内部异常堆栈跟踪结束 at System.IO.__Error.WinIOError(Int32 errorCode，String maybeFullPath) at at System.IO.FileStream.Init(字符串路径、FileMode模式、FileAccess访问、Int32权限、布尔useRights、FileShare共享、Int32 bufferSize、FileOptions选项、SECURITY_ATTRIBUTES secAttrs、String msgPath、布尔bFromProxy、布尔useLongPath) at at System.IO.FileStream..ctor(字符串路径、FileMode模式、FileAccess访问、FileShare共享、Int32 bufferSize、FileOptions选项、字符串msgPath、布尔bFromProxy) at System.IO.FileStream..ctor(字符串路径、FileMode模式、FileAccess访问、FileShare共享) at at System.IO.File.OpenRead(字符串路径) ( at at Microsoft.Xna.Framework.TitleContainer.OpenStream(String name) (在Microsoft.Xna.Framework.Content.ContentManager.OpenStream(String assetName) -内部异常堆栈跟踪结束 (在Microsoft.Xna.Framework.Content.ContentManager.OpenStream(String assetName) 在Microsoft.Xna.Framework.Content.ContentManager.ReadAssetT -内部异常堆栈跟踪结束 在Microsoft.Xna.Framework.Content.ContentManager.ReadAssetT 在Microsoft.Xna.Framework.Content.ContentManager.LoadT 在c:\Users\Flame\Documents\Projects\TestGame\TestGame\Game1.cs:0中的TestGame.Game1.LoadContent() at Microsoft.Xna.Framework.Game.Initialize() 在TestGame.Game1.Initialization()中的c:\Users\Flame\Documents\Projects\TestGame\TestGame\Game1.cs:0 at Microsoft.Xna.Framework.Game.DoInitialize() (在Microsoft.Xna.Framework.Game.Run(GameRunBehavior runBehavior) at Microsoft.Xna.Framework.Game.Run() 在c:\Users\Flame\Documents\Projects\TestGame\TestGame\Program.cs:0中的TestGame.Program.Main()

那我做错什么了？

Answer 1

将png文件的'Build action'设置为'Content'，将'Copy to output directory'设置为'Copy if newer'。

您可以通过ctrl单击文件并按属性来打开Xamarin中的“属性”窗口。

您不应该包括文件扩展名。

Answer 2

您需要将该文件添加到解决方案的内容目录中，如果在“属性”窗口中更新，则将其设置为Content / copy。然后在构建过程中将其复制到输出目录。

请注意，您可以使用预编译的XNB文件(通常使用XNA游戏工作室创建)，也可以使用原始的PNG图像文件。如果使用后者，则需要在代码中添加文件扩展名。

Answer 3

将Content文件夹移到资产中，对于每个资源文件，将“Build action”设置为“AndroidAsset”，并将“Copy to output目录”设置为“Copy(如果更新)”。
