Converting String Type To Windows.UI.Color In Wind

问题:

I'm trying to make a program to parse xml files with predefined format, and add some UI controls to my MainPage in Windows Universal Application.

In some part, I need to specify the background color of my TextBlocks in related xml file, so I'm looking for a way to convert string attribute, read from xml and convert it to Windows.UI.Color corresponding value.

here is my xml file and my C# code to add control

xml :

<test-unit name ="FOG_LAMP"  text ="Fog Lamp"  mode ="DIG_IN" color="ORANGE"/>

C#:

public void AddNewTextBlock(String Name, String Text, String Color)
{
    TextBlock NewTextBlock = new TextBlock();
    NewTextBlock.Name = Name;
    NewTextBlock.Text = Text;
    NewTextBlock.FontSize = 24;
    myGrid.Children.Add(NewTextBlock);
}

Thanks For Help

You can use XamlBindingHelper to convert the string value to Color -

var color = (Color)XamlBindingHelper.ConvertValue(typeof(Color), "ORANGE");
var brush = new SolidColorBrush(color);
NewTextBlock.Foreground = brush;

Use Colors Helper of UWPCommunityToolkit.

Color redColor = "Red".ToColor();
Color redColor = ColorHelper.ToColor("#ff3a4ab0");    //For Alpha code
