MonoGame XNA Helloworld 与 Texture2D

Question

我在使用 Texture2D 类时遇到了一些问题。我很确定这是一个相当简单的问题。我收到以下错误：

Error   1   Expected class, delegate, enum, interface, or struct    D:\_Projects\MonoGameWindowsApplication1\MonoGameWindowsApplication1\Game1.cs   14  13  MonoGameWindowsApplication1

我似乎没有提到 Texture2D 类，但我不知道为什么我没有。任何帮助都会很棒。

Answer 1

将private Texture2D background 变量移动到Game1 类中。

变量必须在class、interface 或struct 中，而不是命名空间。

public class Game1 : Game
{
    private Texture2D background; //Error free
    ...
}

Answer 2

你在一个命名空间中，它需要一个类、委托、枚举、接口或结构。
