如何实现泛型OpenForm方法以允许任何类型的表单

Question

我在FormMain : Form中有以下代码--如何实现OpenForm方法以允许我打开任何类型的Form

    // the method in question
    void OpenFrom<T>()
    {
        // How to implement this generic method to get rid of OpenForm1() and OpenForm2() ???
    }

    // Open Form1 instance
    void OpenForm1()
    {
        new Form1().Show();
    }

    // Open Form2 instance
    void OpenForm2()
    {
        new Form2().Show();
    }

    OpenForm<Form1>(); // instead of OpenForm1()
    OpenForm<Form2>(); // instead of OpenForm2()

Answer 1

这就是你要做的

 void OpenFrom<T>() where T : Form, new()
 {
     new T().Show();
 }
