Question

应用程序是WPF .netframework

我需要将属性作为itemsource绑定到列表框中的类，该类位于.dll中。有一个主要问题，因为如果我绑定一些其他没有模型在dll中的Collection。它有效，但我需要在库中使用它。

的xmlns：C =＆＃34; CLR-名称空间：MessageLibrary;装配= MessageLibrary＆＃34;

我不知道如何修复它，我几乎尝试了一切

我查看了MSDN，并且完全相同的例子没有任何效果。我非常感谢有人解决这个问题

这是MainViewModel中的ItemSourceCollection

 public ObservableCollection<ViewModelUser> AllUsers { get; set; }
 public ObservableCollection<ViewModelRoom> AllRooms { get; set; }
 AllUsers = new ObservableCollection<ViewModelUser>();
 AllRooms = new ObservableCollection<ViewModelUser>();

这是我的xaml类：

<Window x:Class="ChatsUPClient.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:ChatsUPClient"
    xmlns:vm="clr-namespace:ChatsUPClient.ViewModel"
    xmlns:c="clr-namespace:MessageLibrary;assembly=MessageLibrary"
    Title="ChatsUP" Height="600" Width="900">
<Window.DataContext>
    <vm:MainViewModel />
</Window.DataContext>

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="200"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="100"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="24"/>
        <RowDefinition Height="24"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="24"/>
    </Grid.RowDefinitions>
    <TextBlock x:Name="UserNameTextBlock" Grid.Column="1" Grid.Row="0" Text="{Binding Path=LRName, UpdateSourceTrigger=PropertyChanged}" TextAlignment="Right"></TextBlock>
    <TextBox x:Name="MessageTextBox" Grid.Column="1" Grid.Row="3"  TextWrapping="NoWrap" Text="{Binding Path=Input, Mode=TwoWay}"/>
    <TextBox x:Name="MessageTimeLine" Grid.Column="1" Grid.Row="1" Grid.RowSpan="2" TextWrapping="Wrap" Text="{Binding Path=Output}" Grid.ColumnSpan="2" IsReadOnly="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" FontFamily="Lucida Sans Typewriter"/>
    <Button x:Name="SendBtn" Content="Odeslat" Grid.Column="3"  Grid.Row="3" Command="{Binding Path=ProcessCommand}"/>
    <Button x:Name="CreateRoomBtn" Content="Vytvořit místnost"/>
    <TextBox x:Name="CreateRoomName" Grid.Row="1"></TextBox>
    <Grid Grid.Row="2" RenderTransformOrigin="0.505,0.438">
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <ListBox   Grid.Column="0" Grid.Row="2"   ItemsSource="{Binding AllRooms}" >
            <ListBox.ItemTemplate>
                <DataTemplate  DataType="{x:Type c:ViewModelUser}">
                    <TextBlock  Text="{Binding Path= NameOfconversation}"></TextBlock>
                </DataTemplate>
            </ListBox.ItemTemplate>

        </ListBox>
        <ListBox   Grid.Column="0" Grid.Row="0"  ItemsSource="{Binding AllUsers}">
            <ListBox.ItemTemplate>
                <DataTemplate DataType="{x:Type c:ViewModelUser}">
                    <TextBlock Text="{Binding  NickName}"> </TextBlock>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </Grid>
    <Button x:Name="Entry" Grid.Row="3" Grid.Column="0" Content="Vstoupit"></Button>
    <StackPanel Grid.Column="1" Grid.Row="2" VerticalAlignment="Center" x:Name="LoginPanel">
        <TextBlock HorizontalAlignment="Center">Enter Name and Password</TextBlock>
        <TextBox x:Name="NameTextBox" Text="{Binding Path=LRName}"/>
        <TextBox x:Name="PasswordTextBox" Text="{Binding Path=LRPassword}"/>
        <Button Content="Přihlásit se/Registrovat" Command="{Binding Path=LogingCommand}" Click="OnSave" />
    </StackPanel>
</Grid>

库中的

类看起来像这样：

public class ViewModelUser
{
    public int UserId { get; set; }
    public string NickName { get; set; }
    public string Password { get; set; }

}

从库datatemplate绑定列表框项
