十六进制转换code到颜色名称 [英] convert hex code to color name

问题描述

我如何转换这种六code =＃2088C1 成颜色名称，如蓝色或红色

How can i convert this hexa code = #2088C1 into colour name Like Blue or Red

我的目标是我想要得到的颜色名称，如蓝色为给定的六code

My aim is i want to get the colour name like "blue" for the given hexa code

我曾尝试下面的code，但它没有给出任何颜色的名字。

I have tried the below code but it was not giving any colour name ..

System.Drawing.Color col = System.Drawing.ColorTranslator.FromHtml("#2088C1");

Color col = ColorConverter.ConvertFromString("#2088C1") as Color;

但它不会给颜色名称，比如这个aquablue

but it does not giving the colour name like this "aquablue"

我用用C＃的WinForms应用

I am using winforms applications with c#

推荐答案

我偶然发现了一个的德语网站但这正是你想要什么：

I stumbled upon a german site that does exactly what you want:

/// <summary>
/// Gets the System.Drawing.Color object from hex string.
/// </summary>
/// <param name="hexString">The hex string.</param>
/// <returns></returns>
private System.Drawing.Color GetSystemDrawingColorFromHexString(string hexString)
{
    if (!System.Text.RegularExpressions.Regex.IsMatch(hexString, @"[#]([0-9]|[a-f]|[A-F]){6}\b"))
        throw new ArgumentException();
    int red = int.Parse(hexString.Substring(1, 2), NumberStyles.HexNumber);
    int green = int.Parse(hexString.Substring(3, 2), NumberStyles.HexNumber);
    int blue = int.Parse(hexString.Substring(5, 2), NumberStyles.HexNumber);
    return Color.FromArgb(red, green, blue);
}

要得到你可以按如下方式获得<一个使用它的颜色名称href=\"http://msdn.microsoft.com/en-us/library/system.drawing.knowncolor%28v=VS.80%29.aspx\">KnownColor:

To get the color name you can use it as follows to get the KnownColor:

private KnownColor GetColor(string colorCode)
{
    Color color = GetSystemDrawingColorFromHexString(colorCode);
    return color.GetKnownColor();
}
