已经贴了,还问什么呢?

[程先森]

你现在应该问怎么把贴上的代码给去掉。

public static void control_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            Control control = sender as Control;
            ICommand command = (ICommand)control.GetValue(AttachedPropertyHelper.MouseDoubleClickProperty);
            if (command.CanExecute(control.GetValue(AttachedPropertyHelper.IsLeafProperty)))
            {
                command.Execute(control);
            }
        }

[长风破浪会有时1999]

#include <stdio.h> void main() { double a,b ,c,d; d=18.0; c=(a+b+d)*9/26; b=(a+c+d)*6/9; a=(b+c+d)*3/11; a=((a+c+d)*6/9+(a+b+d)*9/26+d)*3/11; printf("%lf\n",a); }

[长风破浪会有时1999]

#include <stdio.h>

void main()
{
double a,b ,c,d;
    d=18.0;
    c=(a+b+d)*9/26;
b=(a+c+d)*6/9;	
a=(b+c+d)*3/11;




   a=((a+c+d)*6/9+(a+b+d)*9/26+d)*3/11;


   printf("%lf\n",a);
}

我也会了，呵呵，请斑竹见谅，第一次没成功
