如何使用C＃在字典中添加颜色 [英] How to add colors in dictionary using C#

问题描述

我想在字典中添加颜色。



例如



如果键是红色 那么它应该有RGB格式的值。



怎么做

I want to add colors in dictionary.

Fro example

If key is "Red" then it should have values in RGB format.

How to do so

<pre lang="c#">
 Dictionary<string, string> ColorInformation = new Dictionary<string, string>();


string colorOrange = "Orange";

           Color Orange = Color.FromName(colorOrange);

           string colorOrangeValue = "R=" + Orange.R + "," + "G=" + Orange.G + "," + "B=" + Orange.B;
           ColorInformation.Add("Orange", colorOrangeValue);
</pre>


I have given the values in string format.
Any other solution for this

推荐答案

// required:
using System.Drawing;

private Dictionary<string, Color> ColorDictionary = new Dictionary<string, Color>();

private void AddColor(string colorName)
{
    Color colorCandidate = Color.FromName(colorName);

    if (colorCandidate.ToArgb() == 0) throw new ArgumentException("Error: No color named:" + colorName + " exists");

    ColorDictionary.Add(colorName, colorCandidate);
}

此示例仅处理System.Drawing.Color中定义的Color Enumeration。



如果使用'FromName如果方法的参数不是有效的Color名称，则返回＃0的结果。在此示例中，如果Color名称无效，则会引发错误。示例：

This example only deals with the Color Enumeration defined in System.Drawing.Color.

If you use the 'FromName method with an argument that's not a valid Color name, it will return a result of #0. In this example an error is thrown if the Color name isn't valid. Example:

// somewhere in a method or EventHandler

// add some Color to the Dictionary
AddColor("Red");
AddColor("Black");

// somewhere in a method or EventHandler

// use a Color in the Dictionary
panel1.BackColor = ColorDictionary["Red"];

继续有了这个 。希望它有所帮助..



字典<字符串，> ColorInformation = new Dictionary< string，>（）;



string color =White;



颜色白= Color.FromName（颜色）;

//颜色将具有适当的RGB值。

Console.WriteLine（white.R）;

Console.WriteLine（white.G）;

Console.WriteLine（white.B）;

Proceed with this . Hope it helps..

Dictionary<string,> ColorInformation = new Dictionary<string,>();

string color="White";

Color white = Color.FromName(color);
// Color will have appropriate R G B values.
Console.WriteLine(white.R);
Console.WriteLine(white.G);
Console.WriteLine(white.B);
