使文本块的宽度自动化

Question

如何将动态创建的文本块的高度和宽度设置为自动？

TextBlock myTextBlock = new TextBlock() { Text = "Text Block", Width = 140, Height = 40, FontSize = 20 };

Answer 1

将宽度(或高度)设置Double.NaN为相当于将宽度设置为autoXAML.

TextBlock myTextBlock = new TextBlock() { Text = "Text Block", Width = Double.NaN, Height = Double.NaN, FontSize = 20 };
