帶Texture2D的MonoGame XNA Helloworld

Question

我在使用Texture2D類時遇到了一些麻煩。我很確定這是一個相當簡單的問題。我得到以下錯誤：

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

我似乎沒有參考Texture2D類，但我不知道爲什麼我不知道。任何幫助都會很棒。

Answer 1

將private Texture2D background變量移動到Game1類中。

變量必須在class,interface或struct而不是命名空間。

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

Answer 2

你在命名空間，它期望一個類，委託，枚舉，接口或結構。
