Set TextBlock to preserve white space at the beginning and at the end?

问题

EDIT:

The code below actually works as I want - this question a little misleading. Please ignore it.

---

Normally when I set Text property of TextBlock like this:

TextBlock tb = new TextBlock();
tb.Text = "     Hello World ";

The whitespace at the beginning and at the end of text are not shown. The text shown by TextBlock is only Hello World. How can I set TextBlock to display them (i.e., not remove the whitespace)? Am I missing some property?

回答1:

In this case you don't need to use xml:space="preserve"

<TextBlock xml:space="preserve" Text="     Hello world!    " />

WILL display the whitespaces, however

<TextBlock>    Hello world!    </TextBlock>

won't.

Sounds like you might want to use the Padding property: http://msdn.microsoft.com/en-us/library/system.windows.controls.textblock.padding(VS.85).aspx.

See also the various alignment & margin properties.

set the xml:space property to preserve in your XAML, i assume you are using WPF

<TextBlock xml:space="preserve" Text="     Hello world!    " />

EDIT: It is sometimes easier to do things in XAML. I just hope you are not using this to align your text. There are many other more elegant methods to do so.
