C# 是否可以绑定任何textcontrol的前景色

所以我三天来一直在想这个问题，但似乎找不到解决办法

这就是我想要达到的目标。 我有一个简单的WPF项目，里面有一个RichTextBox。 我的应用程序所做的是，它的行为类似于CMD

我现在要做的是，我想更改它在按enter键时保存的消息，我想更改上一条消息的颜色

这是一个GIF显示它看起来像什么

我试着将文本框的前景绑定到DataTemplate中，但这只会使文本无法显示

<DataTemplate>
                            <TextBlock Text="{Binding Path=.}" Foreground="White" Name="SavedBlocks" FontFamily="Consolas"/>
                        </DataTemplate>

ConsoleContent.cs

public class ConsoleContent : INotifyPropertyChanged
{
    string consoleInput = string.Empty;
    ObservableCollection<string> consoleOutput = new ObservableCollection<string>() { "Console Emulation Sample..." };

    public string ConsoleInput
    {
        get
        {
            return consoleInput;
        }
        set
        {
            consoleInput = value;
            OnPropertyChanged("ConsoleInput");
        }
    }

    public ObservableCollection<string> ConsoleOutput
    {
        get
        {
            return consoleOutput;
        }
        set
        {
            consoleOutput = value;
            OnPropertyChanged("ConsoleOutput");
        }
    }

    public void RunCommand()
    {
        ConsoleOutput.Add(ConsoleInput);
        //myBrush = Brushes.Orange;
        // do your stuff here.
        ConsoleInput = String.Empty;
    }



    private System.Windows.Media.Brush _foregroundColor = System.Windows.Media.Brushes.DarkSeaGreen;

    public System.Windows.Media.Brush ForegroundColor
    {
        get { return _foregroundColor; }
        set
        {
            _foregroundColor = value;
            OnPropertyChanged("ForegroundColor");
        }
    }


    public event PropertyChangedEventHandler PropertyChanged;
    void OnPropertyChanged(string propertyName)
    {
        if (null != PropertyChanged)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }
}

将consoleOutput的类型从ObservaleCollection更改为ObservaleCollection，其中YourType是一个用文本字符串和前景笔刷表示输入行的类：

绑定到XAML中此类的属性：

<ScrollViewer Name="Scroller" Margin="0" Background="Black">
    <StackPanel>
        <ItemsControl ItemsSource="{Binding ConsoleOutput, Mode=OneWay}">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Text}" 
                               Foreground="{Binding Foreground}" 
                               Name="SavedBlocks" FontFamily="Consolas"/>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
        <TextBox Text="{Binding ConsoleInput, Mode=TwoWay}" Background="Black" Foreground="White" FontFamily="Consolas" Name="InputBlock" BorderBrush="{x:Null}" SelectionBrush="{x:Null}" />
    </StackPanel>
</ScrollViewer>

将ObservaleCollection更改为ObservaleCollection，并设置并绑定到YourType上的前台属性？@mm8但它只会打印出这个，我觉得我需要打印类的属性，现在它似乎正在打印类。当然，需要为这个类型更新数据模板。在您自己的类型上，您应该重写ToString方法以返回属性值。@NerdzIT:请看我的答案。这很有道理！非常感谢。
