C#wpf如何从Main调用initializeComponent

Question

我遇到了ac#code的问题.首先,我不是开发人员,我刚刚接受了这个项目,这对我来说真的很令人沮丧.但供应商提供了一些代码供我们运行.代码没有Main()函数,我猜这将是入口点,所以我试图在创建WPF项目时根据默认代码添加它...在VS2012中

这是代码.这是xaml窗口的C#代码.在最后,您可以看到我正在尝试添加Main()来调用initializeComponent.但我收到一些错误.

        Interfaces.Connection.ConnectionDialog app = new Interfaces.Connection.ConnectionDialog();
        app.InitializeComponent();
        app.Run();
    }
}

}

我得到的一个错误是:

Interfaces.Connection.ConnectionDialog'不包含带0个参数的构造函数.

不确定构造函数是什么,不确定我需要传递哪些参数.

另一个错误:

Interfaces.Connection.ConnectionDialog'不包含'Run'的定义,也没有扩展方法'Run'接受类型Interfaces.Connection.ConnectionDialog'的第一个参数(你是否缺少using指令或程序集引用？)

每当你在VS中创建一个WPF C#项目时,我就会从默认代码中复制.Run().如果不需要,我可以把它拿出来.

如何在我的场景中从Main()初始化Component？如上所述,我不是ac#dev,所以如果你可以请尽可能少的技术,以便初学c#的人会理解,那真的很棒!

如果您有进一步的澄清问题,我会尽力回答.

提前致谢.

Answer 1

首先,您发布的代码看起来像生成的代码.它根本不应该手动触摸.

此外,您不需要MainWPF应用程序中的方法.当您刚刚创建一个新的WPF项目时,您也没有Main方法.框架在幕后为您生成,并自动显示主窗口.如果要在应用程序启动时执行某些操作,该App.xaml文件将包含一个Application具有Startup事件的对象.使用此而不是Main方法.

此外,InitializeComponent应该由框架自动调用.无需手动调用它.
