How to set text of existing TextBlock dynamically

Question

What's the correct way to find and set the text for an existing TextBlock dynamically? I can't seem to find the relevant tutorial anywhere.

XAML

<TextBlock x:Name="PageTitle" Style="{StaticResource BodyTextBlockStyle}" />

C#

var txtTitle =???;
txtTitle.Text = "Hello World";

Hello,

Welcome to Microsoft Q&A!

The x:Name uniquely identifies object elements for access to the instantiated object from code-behind or general code. So if you want to get or set the text of TextBlock in code-behind, just using the specified x:Name which holds a reference to the TextBlock. For example:

.cs:

string txtTitle = PageTitle.Text; //get Text
PageTitle.Text = "Hello World"; //set Text
