            }
        }

    }
}

这些是我收到的错误：

  

方法必须具有返回类型@第48行，第16列

     

当前上下文中不存在名称'InitializeComponent'@   第50行，第13栏

     

当前上下文@Line 127中不存在名称'textBox1'，   第13栏

     

当前上下文@Line 117中不存在名称'textBox2'，   第13栏

     

当前上下文@第143行中不存在名称'textBox3'，   第21栏

     

当前上下文@Line 146中不存在名称'textBox3'，   第21栏

我从here获得了代码，并假设它只是被复制/粘贴，因为我不正确地设置了我的Kinect项目。

修改

这就是我将代码更改为：

在我运行之前我没有错误，而且发生了这种情况：

  

程序：'C：\ Users \\ Documents \ Visual Studio   2010 \ Projects \ 1 \ 1 \ 1 \ _对象\ Debug \ 1.exe'不包含静态'Main'   适合入境点的方法

Answer 1

欢迎使用stackoverflow，请考虑阅读FAQ以获得最佳结果，您将遇到第一个错误，因为类名与其构造函数不匹配！因此，您应该将第48行中的MainWindow()更改为JARVIS()

    public JARVIS()
    {
        InitializeComponent();
        InitializeKinect();
    }

正如您的来源已经提到的那样，您需要向项目添加三个textboxes，其名称为textBox1，textBox2和textBox3

如果您不需要那些textboxes只需将代码更改为您想要的任何内容

• 更新：尝试启动一个新项目并向项目中添加一个类，然后将代码粘贴到类中并在项目中使用该类，但请记住只是复制和粘贴一堆除非你确切地知道你正在做什么，否则代码并没有什么帮助，而且你也无法启动项目并粘贴其他代码而不是它自己的函数和类，并期望应用程序运行得非常完美，请考虑编写代码自我，这将是一个更好的选择，在你的情况下，你可能会得到更快的结果！
