Answer 1

您可以使用offset

执行此操作

<TextBlock FontSize="72">
    <Run Foreground="Gray" Text="It" /><Run Text="e">
        <Run.Foreground>
            <LinearGradientBrush StartPoint="0,0.5" EndPoint="1,0.5">
                <GradientStop Color="Gray" Offset="0"/>
                <GradientStop Color="Gray" Offset="0.5" />
                <GradientStop Color="Red" Offset="0.5" />
                <GradientStop Color="Red" Offset="1" />
            </LinearGradientBrush>
        </Run.Foreground>
    </Run><Run Text="m" Foreground="Red" /><Run Text=" 1">
        <Run.Foreground>
            <LinearGradientBrush StartPoint="0,0.5" EndPoint="1,0.5">
                <GradientStop Color="Red" Offset="0"/>
                <GradientStop Color="Red" Offset="0.5" />
                <GradientStop Color="Gray" Offset="0.5" />
                <GradientStop Color="Gray" Offset="1" />
            </LinearGradientBrush>
        </Run.Foreground>
    </Run>
</TextBlock>
