很好的冬冬

public partial class Form1 :

Form { public Form1() { InitializeComponent(); }

private void button1_Click(object sender, EventArgs e) { m_Class m = new m_Class(); m.t.Show(); } } public class m_Class where T : new()

{ public T t; public m_Class()

     t = new T();//等同于非泛型版本的new? 例如 object o = new object();? }

}
