C# 按钮不能禁用

我想当我点击一个按钮时，背景图像会变为另一个，当我松开按钮时，会变回原来的图像。经过大量的研究，我发现这一点，这对我有很大帮助，而且效果很好！但问题是，我不能禁用按钮，它显示它已禁用，但如果我单击它，它的工作原理就像它未被禁用一样！这是代码的一部分

using System;
using System.Windows;
using System.Windows.Media.Imaging;

namespace DotNetApp
{
    public partial class ButtonImage
    {
        #region Fields

        public new static readonly DependencyProperty IsEnabledProperty = DependencyProperty.Register("IsEnabled", typeof (bool), typeof (ButtonImage), null);
        public static readonly DependencyProperty ImageSourceProperty = DependencyProperty.Register("ImageSource", typeof (string), typeof (ButtonImage), null);
        public static readonly DependencyProperty ImagePressedSourceProperty = DependencyProperty.Register("ImagePressedSource", typeof (string), typeof (ButtonImage), null);

                SetImageFromState();
            }

                image.Source = _imageDisabled;

            else if (_isPressed)
            {
                image.Source = _imagePressed;

            }
        }

这是XAML

<Tap_Test:ButtonImage ImageSource="/images/buttons/star2.png"
                              ImageDisabledSource="/images/buttons/star2lock.png"
                              ImagePressedSource="/images/buttons/star2-2.png"
                              Style="{StaticResource ButtonImageStyle}"
                              x:Name="star2" Margin="136,80,134,480" BorderBrush="{x:Null}" Click="star2_Click" IsEnabled="False"/>

你可以在我提供的链接上查看完整的代码！我试过

star2.IsEnable=false也是，但它不起作用。有什么建议吗？谢谢
 > P>我认为问题来自于“SETIMAGOFF STATE（）”方法总是运行，需要一种阻止它运行的方法，考虑如下：

private bool _disableButton;

public bool disableButton { 
                              get { return _disableButton; }
                              set { 
                                     _disableButton = value;
                                     SetValue(IsEnabledProperty, !_disableButton);           

                                  } 
                             }

public new bool IsEnabled
    {
        get { return (bool)GetValue(IsEnabledProperty); }

        set
        {
            if(!disableButton)
             {
                SetValue(IsEnabledProperty, value);
                SetImageFromState();
             }


        }
    }

因此，如果你想真正禁用按钮，你会去

myButton.disableButton = true;

Hi@KillaKem谢谢你的帮助，但是出现了这个错误App.ButtonImage.DisableButton.get必须声明一个主体，因为它没有标记为抽象、外部或部分。知道为什么吗？编译器想要一个主体作为disableButton的getter，检查编辑的代码是否解决了问题。哦，我明白了，谢谢，但按钮仍然没有被禁用：（我仍然可以单击它。查看代码编辑并重试。应该是“SetValue（IsEnableProperty，！\u disableButton）；”还是不行吗？/同样的事情，兄弟，有什么想法吗？我想用两个按钮以不同的方式来做
