WPF中让TextBlock每一个字符显示不同的颜色
XAML代码:
<TextBlock x:Name="tb"> <Run Foreground="Red">R</Run> <Run Foreground="Green">G</Run> <Run Foreground="Blue">B</Run> <Run Text="Gradient"> <Run.Foreground> <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> <GradientStop Color="#FF000000" Offset="0"/> <GradientStop Color="#FFFFFFFF" Offset="1"/> </LinearGradientBrush> </Run.Foreground> </Run> </TextBlock>
在后台的逻辑代码中应访问TextBlock的Inlines集合来得到它所包含的字串..如果你用Text属性是取不到值的..
CS代码:
string str1 = this.tb.Text;
string str2 = "";
foreach (Run r in tb.Inlines)
{
str2 += r.Text;
}
MessageBox.Show("str1:["+str1+"] str2:["+str2+"]");
运行结果:
