c# - 方法无法显式调用运算符或访问器

Question

我添加了.dll:AxWMPLib并使用了get_Ctlcontrols()方法，但显示如下错误:

AxWMPLib.AxWindowsMediaPlayer.Ctlcontrols.get': cannot explicitly call operator or accessor

这是我使用get_Ctlcontrols()方法的代码:

this.Media.get_Ctlcontrols().stop();

我不知道为什么会出现此错误。谁能解释我以及如何解决这个问题？

看起来您正在尝试通过显式调用其get方法来访问属性。

尝试以下操作(注意，缺少get_和()):

this.Media.Ctlcontrols.stop();

这是一个关于属性如何在C#中工作的小例子-只是为了使您理解，这并不假装是准确的，因此请阅读比这更严重的内容:)

using System;

class Example {

    int somePropertyValue;

    // this is a property: these are actually two methods, but from your 
    // code you must access this like it was a variable
    public int SomeProperty {
        get { return somePropertyValue; }
        set { somePropertyValue = value; }
    }
}

class Program {

    static void Main(string[] args) {
        Example e = new Example();

        // you access properties like this:
        e.SomeProperty = 3; // this calls the set method
        Console.WriteLine(e.SomeProperty); // this calls the get method

        // you cannot access properties by calling directly the 
        // generated get_ and set_ methods like you were doing:
        e.set_SomeProperty(3);
        Console.WriteLine(e.get_SomeProperty());

    }

}
