如何制作新颜色？ [英] How can I make a new color?

问题描述

我在C＃中有一个表单，想要在3个 TextBox 控件中输入为红色，绿色和蓝色，并设置新的颜色。例如：当我单击 MAKE COLOR按钮时，红色= 3，绿色= 2，蓝色= 5
，标签将为我显示新颜色。

I have a form in C# that I want to enter as red, green and blue in 3 TextBox controls and make a new color. For example: red=3, green=2, blue=5 when I click on "MAKE COLOR" button, a label shows me the new color.

推荐答案

让我们假设您有一些类似于以下的代码：

Let us assume that you have some code that looks similar to this:

int red = Convert.ToInt32(RedColorComponentValueTextBox.Text);
int green = Convert.ToInt32(GreenColorComponentValueTextBox.Text);
int blue = Convert.ToInt32(BlueColorComponentValueTextBox.Text);
//Don't forget to try/catch this

然后从中创建颜色这些值，请尝试

Then to create the color from these values, try

Color c = Color.FromArgb(red, green, blue);

然后设置 ForeColor 属性（或标签的 BackColor 属性-不知道要更改哪一个），将标签更改为 c 。

Then set the ForeColor property (or the BackColor property -- not sure which one you meant to change) of the label to c.

您需要使用System.Drawing

You will need to have

using System.Drawing;

在您的代码文件（或类）序言中。

in your code file (or class) preamble.

注意：如果您还希望具有alpha分量，则可以尝试以下操作：

Note: If you wanted to also have an alpha component, you could try this:

Color c = Color.FromArgb(alpha, red, green, blue);

一般提示：如果要使用<$ c $格式的HTML / CSS颜色规范c> #RRGGBB 例如＃335577 ，尝试以下模式

General hint: If you want to use an HTML/CSS color specification of the form #RRGGBB e.g. #335577, try this pattern

int red = 0x33, green = 0x55, blue = 0x77;
