在标签内获取/设置TextBlock XML文本值

Question

I can get and set the Text property of a TextBlock but i don't know to get the text corresponding the the one inside XAML:

<TextBlock x:Name="myTextBlock">This is what i want to get/set</TextBlock>

I want to add html special characters/codes that's why the "text" attribute doesn't help, for example:

<TextBlock x:Name="myTextBlock">&#160;&#160;Whatever<LineBreak />More Text</TextBlock>

Which works perfectly inside TextBlock tags but not when setting the property

myTextBlock.Text = "whatever..."

which breaks the content and instead shows:

&#160;&#160;Whatever<LineBreak />More Text

Answer 1

First of all, the Text attribute sets the Text property, the element content corresponds to the Inlines collection, which can be mixed content. Text is essentially shorthand for a single Run .

If you want to set those in code you can do that, but the encoding of Unicode works differently. If you want line breaks as in XAML you can either build the same structure using Runs for strings and the LineBreak inlines or encode the line-break directly.

In a normal C# string you can use \\uXXXX syntax. For 💤 it would be "\?\?" .

If you have complex text with styling you will need to read the Inlines to get all the information from the TextBlock .
