C# XNA文件未找到问题-指定的设置正确（即，这应该可以正常工作）

我有下面的Game1类，我对它做了一些修改（呵呵，这可能是它不能正常工作的原因…）：

游戏1类

公共精灵（浮点x、浮点y、字符串assetName、ContentManager）
{
_位置=新矢量2（x，y）；
_texture=contentManager.Load（assetName）；//错误：找不到文件
}

错误就发生在这里：我需要引用一个.png文件（它加载在外部内容文件中，具有相同的名称，并且有一个

纹理的导入器/处理器

），但它没有加载。如图所示，

fileAsset

名称为“pacmansprite”

有没有人能看出我做错了什么？如果需要，我会发布更多的代码，但现在我认为这应该足够了。

我在您的代码中看到的第一个错误，与您的异常无关：您确实应该在

LoadContent

中加载内容，而不是在

Draw

中加载内容。特别是考虑到您正在每一帧创建一个新的精灵对象。您应该考虑完全放弃SpRITE控制器和精灵类——它们似乎是不必要的间接层。

下一个错误：您设置自己的

\u contentManager

的方式似乎是错误的。如果要加载纹理，则传入的服务容器需要包含

GraphicsDeviceService

。您应该输入

Game.Services

，或者，更好的做法是使用

Game.Content

而不是创建自己的内容

最后，你的例外：你没有提供足够的信息来确定你得到它的确切原因。但以下是如何找出问题所在：

首先，您需要找出它试图从中加载纹理的路径。这是

RootDirectory

和资产名称的组合，加上

.xnb

文件扩展名。在我看来，它似乎正在尝试加载

Content\pacmansprite.xnb

因此，下一步是查看构建目录（

bin\x86\Debug

或类似目录） 并查看该路径是否存在文件。如果没有，则需要修改内容项目，以便内容生成输出显示在那里

（游戏项目需要引用内容项目，并且需要正确设置其根目录属性。资源需要具有正确的资产名称属性（以及其他设置）。）

如果遇到问题，可以尝试使用默认模板创建新项目，并直接加载和绘制资源。然后从那里开始工作。

谢谢你的帮助。我很感激你提供的信息，我会接受你的建议。
