编译错误的Windows Phone
问题描述:
我是新的Windows手机动画和使用下面的代码,但它给我的编译错误:编译错误的Windows Phone
“System.Windows.Controls.Button”不包含“BeginAnimation的定义'并没有扩展方法'BeginAnimation'接受类型'System.Windows.Controls.Button'的第一个参数可以找到(你是否缺少使用指令或程序集引用?)
我缺少哪个引用?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
private void button1_Click(object sender, RoutedEventArgs e)
{
DoubleAnimation da = new DoubleAnimation();
da.From = 30;
da.To = 100;
da.Duration = new Duration(TimeSpan.FromSeconds(1));
button1.BeginAnimation(Button.HeightProperty, da);
}
答
WP7中不存在UIElement.BeginAnimation方法。相反,您将需要创建一个故事板,如下所示:
private void button1_Click(object sender, RoutedEventArgs e)
{
var sb = new Storyboard();
var db = CreateDoubleAnimation(30, 100,
button1, Button.HeightProperty, TimeSpan.FromMilliseconds(1000));
sb.Children.Add(db);
sb.Begin();
}
private static DoubleAnimation CreateDoubleAnimation(double from, double to,
DependencyObject target, object propertyPath, TimeSpan duration)
{
var db = new DoubleAnimation();
db.To = to;
db.From = from;
db.Duration = duration;
Storyboard.SetTarget(db, target);
Storyboard.SetTargetProperty(db, new PropertyPath(propertyPath));
return db;
}
WP7!= WPF。你在使用哪一个? – SLaks 2012-03-13 01:39:33

Windows Phone并不是WPF。 – SLaks 2012-03-13 01:43:45
