【问题描述】:
所以,我纠正了几乎所有的错误,但如果我可以说,这里还有一个更重要的问题。所以我创建了一个名为 MessageBoxEx.xaml 的 xaml,带有“加载的名称:Window_Loaded”、一个名为“PartTextBlock”的文本块和一个名为“PartStackPanel”的堆栈面板。这是上面显示的xaml代码:
<Window x:Class="MyProject.MoLib.MessageBoxEx"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Loaded="Window_Loaded" Height="160" Width="440" WindowStyle="None" AllowsTransparency="true"
Background="Transparent" WindowStartupLocation="CenterOwner">
<Border CornerRadius="10" BorderBrush="{DynamicResource AccentBrush}" BorderThickness="3"
Background="{DynamicResource BackgroundBrush}">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal" Height="112">
<TextBlock x:Name="PartTextBlock" Foreground="#000000" TextWrapping="Wrap"
Width="400" Height="Auto" Margin="20,34,10,6" TextAlignment="Center" VerticalAlignment="Center"/>
</StackPanel>
<StackPanel Name="PartStackPanel" Orientation="Horizontal" HorizontalAlignment="Right"/>
</StackPanel>
</Border>
然后我把这些元素的名字,让它们被引用并实现一个功能,在MessageBoxEx.xaml.cs,代码如下:
using System;
using System.ComponentModel;
using System.Diagnostics;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Markup;
namespace MyProject.MoLib
{
public partial class MessageBoxEx : Window, IComponentConnector
{
private string FMessage = string.Empty;
private string FResult = (string)null;
private string FBtn0 = (string)null;
private string FBtn1 = (string)null;
private string FBtn2 = (string)null;
internal TextBlock PartTextBlock;
internal StackPanel PartStackPanel;
private bool _contentLoaded;
public string Btn0
{
get
{
return this.FBtn0;
}
set
{
this.FBtn0 = value;
}
}
public string Btn1
{
get
{
return this.FBtn1;
}
set
{
this.FBtn1 = value;
}
}
public string Btn2
{
get
{
return this.FBtn2;
}
set
{
this.FBtn2 = value;
}
}
public string Message
{
get
{
return this.FMessage;
}
set
{
this.FMessage = value;
}
}
public string Result
{
get
{
return this.FResult;
}
}
public TextBlock TextBlock
{
get
{
return this.PartTextBlock;
}
}
public MessageBoxEx()
{
this.InitializeComponent();
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
if (this.PartTextBlock.Inlines.Count < 1)
this.PartTextBlock.Text = this.FMessage;
this.SetupButton();
}
protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
{
base.OnMouseLeftButtonDown(e);
this.DragMove();
}
private void SetupButton()
{
if (this.FBtn0 != null)
this.CreateButton("btn1", this.FBtn0);
if (this.FBtn1 != null)
this.CreateButton("btn2", this.FBtn1);
if (this.FBtn2 != null)
this.CreateButton("btn3", this.FBtn2);
Border border = new Border();
border.Width = 10.0;
this.PartStackPanel.Children.Add((UIElement)border);
}
private void button_Click(object sender, EventArgs e)
{
Button button = sender as Button;
if (button.Name == "btn1")
this.FResult = "0";
else if (button.Name == "btn2")
this.FResult = "1";
else if (button.Name == "btn3")
this.FResult = "2";
this.Close();
}
private void CreateButton(string name, string caption)
{
Button button = new Button();
button.Name = name;
button.Width = 80.0;
button.Content = (object)caption;
button.Margin = new Thickness(0.0, 15.0, 4.0, 0.0);
button.Click += new RoutedEventHandler(this.button_Click);
this.PartStackPanel.Children.Add((UIElement)button);
}
[DebuggerNonUserCode]
public void InitializeComponent()
{
if (this._contentLoaded)
return;
this._contentLoaded = true;
Application.LoadComponent((object)this, new Uri("/MoLib/MessageBoXex.xaml", UriKind.Relative));
}
[EditorBrowsable(EditorBrowsableState.Never)]
[DebuggerNonUserCode]
void IComponentConnector.Connect(int connectionId, object target)
{
switch (connectionId)
{
case 1:
((FrameworkElement)target).Loaded += new RoutedEventHandler(this.Window_Loaded);
break;
case 2:
this.PartTextBlock = (TextBlock)target;
break;
case 3:
this.PartStackPanel = (StackPanel)target;
break;
default:
this._contentLoaded = true;
break;
}
}
}
}
Hop,名字变红了,VS 对我说:模棱两可,已经同名了。即使是 InitializeComponent()、IComponentConnector.Connect 和 _contentLoaded。
显然,当我更改类的名称时,此错误会消失,但如果我这样做,.xaml 的类就会变为 false。
我还要指出,如果我更改类的名称,xaml 的对象“Loaded ="Window_Loaded”' 不再被 xaml.cs 引用,然后它会变成红色。
那么,我该怎么做才能纠正呢?是否可以在MessageBoxEx.xaml 中引用MessageBoxEx.xaml.cs 中已经存在的名称?我还添加了 URI 方法,以防我输入相同的名称时出错。
你如何进行?
【问题讨论】:
-
你需要修改
MessageBoxEx.xaml.cs文件,而不是MessageBoxEx.g.i.cs,编译器会自动生成g.i.cs。 -
@Nikita 我不修改
MessageBoxEx.g.i.cs我修改MessageBoxEx.xaml.cs。我很难表达自己?我会改变方式,所以我指定了这个 -
...为什么需要在你的代码中实现
IComponentConnector接口? -
@Nikita 提供对命名 XAML 元素的支持以及事件处理程序与它们的关联......我的项目在框架 3.5 中。如有必要,我会删除它......我遇到的问题的目标将很难进行任何操作
-
@Nikita ... 而
IComponentConnecter不是这些错误的问题
