Question

实际上，Windows Phone提供黑色背景的默认消息框。我已经使用其工具包使用自定义消息框。它有背景属性但我无法分配任何值。它给出了类型转换错误。

希望所以有人会告诉正确的价值，我也试过（0,0,0,0）/“grey”/ colors.grey但同样的错误

CustomMessageBox msgbox = new CustomMessageBox()
{
Caption = "Memory Race",
Message ="This is custom message box!",
LeftButtonContent = "OK",
Background = "what?"
};

Answer 1

您可以设置背景颜色

Background =  new SolidColorBrush(Colors.Green);

Answer 2

背景属性是一种颜色画笔。你必须这样做：

*.Background = new SolidColorBrush(ConvertStringToColor("#0D0D0E"));

private Color ConvertStringToColor(String hex)
    {
        //remove the # at the front
        hex = hex.Replace("#", "");

        byte a = 255;
        byte r = 255;
        byte g = 255;
        byte b = 255;

        int start = 0;

        //handle ARGB strings (8 characters long)
        if (hex.Length == 8)
        {
            a = byte.Parse(hex.Substring(0, 2), System.Globalization.NumberStyles.HexNumber);
            start = 2;
        }

        //convert RGB characters to bytes
        r = byte.Parse(hex.Substring(start, 2), System.Globalization.NumberStyles.HexNumber);
        g = byte.Parse(hex.Substring(start + 2, 2), System.Globalization.NumberStyles.HexNumber);
        b = byte.Parse(hex.Substring(start + 4, 2), System.Globalization.NumberStyles.HexNumber);

        return Color.FromArgb(a, r, g, b);
    }
