How do I dynamically change color in C# to a hex value?
提问by Lill Lansey
I know how to set a control's BackColor dynamically in C# to a named color with a statement such as Label1.BackColor = Color.LightSteelBlue; ( using System.Drawing; )
我知道如何使用诸如 Label1.BackColor = Color.LightSteelBlue; 之类的语句在 C# 中将控件的 BackColor 动态设置为命名颜色。( 使用 System.Drawing; )
But how do I convert a hex value into a System.Color , ie Label1.BackColor = "#B5C7DE
但是如何将十六进制值转换为 System.Color ，即 Label1.BackColor = "#B5C7DE

I would use the color translator as so:
我会这样使用颜色转换器：
var color = ColorTranslator.FromHtml("#FF1133");
Hope this helps.
希望这可以帮助。

Color.FromArgb(0xB5C7DE);
or, if you want to parse the string
或者，如果你想解析字符串
private Color ParseColor(string s, Color defaultColor)
{
try
{
ColorConverter cc = new ColorConverter();
Color c = (Color)(cc.ConvertFromString(s));
if (c != null)
{
return c;
}
}
catch (Exception)
{
}
return defaultColor;
}
This function just returns the default if it can't parse s. You could just let the exception through if you'd rather handle exceptions yourself.
如果无法解析 s，此函数仅返回默认值。如果您更愿意自己处理异常，则可以让异常通过。

string hexColor = "#B5C7DE";
Color color = ColorTranslator.FromHtml(hexColor);

You can use the Color.FromArgb method:
您可以使用 Color.FromArgb 方法：
Label1.BackColor = Color.FromArgb(0xB5C7DE);
