我认为标题很清楚!
我现在拥有的是:
System.Drawing.Color uiui = System.Drawing.ColorTranslator.FromHtml(myString);
var intColor = (uint)((uiui.A << 24) | (uiui.R << 16) | (uiui.G << 8) | (uiui.B << 0));
var bytes = BitConverter.GetBytes(uint.Parse(value));
var brush = new SolidColorBrush();
brush.Color = Color.FromArgb(bytes[3], bytes[2], bytes[1], bytes[0]);
1- myString就像我在标题中所说的那样#FFFFFF
2-这在BitConverter.GetBytes行上失败了,这让我感到惊讶,因为我在我的Color上得到了int表示!
3-无论如何,我知道COlor转换不是那么直观,但我觉得我做得不对...... 这是好方法吗?

您可以使用System.Windows.Media.ColorConverter
var color = (Color)ColorConverter.ConvertFromString("#FF010203");
//OR
var color = (Color)ColorConverter.ConvertFromString("#010203");
//OR
var color = (Color)ColorConverter.ConvertFromString("Red");
//and then:
var brush = new SolidColorBrush(color);
它接受的内容非常灵活。看看examples in XAML here。您可以在。
中传递任何这些字符串格式注意:这些都在System.Windows.Media
(对于WPF),不要与System.Drawing
混淆(对于WinForms)

这是我过去使用的助手类
public static Color HexStringToColor(string hexColor)
{
string hc = ExtractHexDigits(hexColor);
if (hc.Length != 6)
{
// you can choose whether to throw an exception
//throw new ArgumentException("hexColor is not exactly 6 digits.");
return Color.Empty;
}
string r = hc.Substring(0, 2);
string g = hc.Substring(2, 2);
string b = hc.Substring(4, 2);
Color color = Color.Empty;
try
{
int ri = Int32.Parse(r, NumberStyles.HexNumber);
int gi = Int32.Parse(g, NumberStyles.HexNumber);
int bi = Int32.Parse(b, NumberStyles.HexNumber);
color = Color.FromArgb(ri, gi, bi);
}
catch
{
// you can choose whether to throw an exception
//throw new ArgumentException("Conversion failed.");
return Color.Empty;
}
return color;
}
和一个额外的助手类
public static string ExtractHexDigits(string input)
{
// remove any characters that are not digits (like #)
var isHexDigit
= new Regex("[abcdefABCDEF\\d]+", RegexOptions.Compiled);
string newnum = "";
foreach (char c in input)
{
if (isHexDigit.IsMatch(c.ToString()))
{
newnum += c.ToString();
}
}
return newnum;
}

Just use ColorTranslator method:
ColorTranslator.FromHtml("#010203");
