这有什么错误？这将返回加载“character.png”的错误。文件未找到。我创建了 character.png 并将其添加到我的项目中，但它也不起作用我使用 Visual Studio 2010 C# xna 4.0

标签： c# visual-studio-2010 xna xna-4.0

【解决方案1】：

试试这个：

myTexture = Content.Load<Texture2D>("character");

编辑：如果仍然无法正常工作，请确保将文件设置为使用正确的内容导入器，如下所述：http://msdn.microsoft.com/en-us/library/bb313966.aspx。

【讨论】：

转到文件的属性并确保 Content Importer 设置为 Texture - XNA Framework 并且 Content Processor 设置为 Texture - XNA Framework。
离开 LoadContent 方法时，myTexture 将超出范围。 myTexture 需要是类级别的变量。
@MattDavey 谢谢，我回答问题时没听懂。

【解决方案2】：

这样做：

Texture myTexture = Content.Load<Texture2D>("character");

为什么有效？
ContentManager.Load 方法接受资产名称，而不是文件路径。您需要在解决方案资源管理器中单击资产，然后找到资产名称。这是 Load 方法的参数。
希望这对您有所帮助并祝您未来好运！
