如何从 wpf 中的方法调用返回格式化文本 [英] How to return formatted text from a method call in wpf

问题描述

我正在开发一个插件界面，我希望有一种方法可以以一种 WPF 控件可以只显示插件结果的方式返回格式化文本.返回该文本的最佳方式是什么?

I'm developing a plugin interface and I would like to have one method that returns formatted text in a way that a WPF control can just show the plugin result. What would be the best way to return that text?

这样我只需要将插件结果分配给 WPF 文本控件(可能是 RichTextBox 或类似的东西).

This way I will only need to assign the plugin result to a WPF text control (maybe a RichTextBox or something like that).

我想支持粗体、下划线等...

I would like to support bold, underline, etc ...

总而言之，我正在从字符串格式"中进行搜索，该字符串允许第 3 方编码人员返回一个带有编码格式的简单字符串，因此我只需要执行以下操作:

Summarizing, I'm searching from a string "format" that allow 3rd party coders to return me a simple string with encoded format so I just need to do:

 myRichTextBox.Text = (IPlugin)3rdPartyPlugin.ExecutePlugin();

文本显示格式.

推荐答案

返回格式化文本的方法背后有多种代码......

There are various Code behind ways to return a formatted text...

1] 作为文本

WPF 流文档和内联

2] 作为图形呈现的文本...

2] As a graphically rendered text ...

在任何自定义控件的重写 OnRender() 方法中，您可以以图形方式将格式化文本绘制为绘图...

In any custom control's overriden OnRender() method you can graphically paint the formatted text as a drawing ...

    protected override void OnRender(DrawingContext drawingContext)
    {
        this.formattedToolTip = new FormattedText(
                (string)this.TextProperty,
                System.Globalization.CultureInfo.CurrentCulture,
                FlowDirection.LeftToRight,
                new Typeface(
                     new FontFamily("Arial"),
                     FontStyles.Normal,
                     FontWeights.Bold,
                     FontStretches.Normal),
                11,
                new SolidColorBrush(Colors.Black));

        drawingContext.DrawText(
                this.formattedToolTip,
                new Point(10, 10)); //// Margin of 10 pixels from top and left.
    }
