电阻颜色代码 [英] Resistor color code

问题描述

我用C#制作了将电阻值转换为颜色代码的应用程序.

I made app in C# that convert resistor value to color codes.

如何显示颜色而不是文本.例如，如果我输入15K，它将显示棕色，绿色和橙色，而不是文本.

当我设置label15.BackColor = colours(res [0]-'0')
我收到错误消息，无法将类型字符串隐式转换为System.Drawing.Color

When I set label15.BackColor=colours(res[0] - '0')
I get error cannot implicitly convert type string to System.Drawing.Color

推荐答案

您可以使用Color.FromName方法转换名称颜色，只要您的颜色名称与System.Drawing.Color中的成员名称匹配即可.

You can use the Color.FromName method to convert the name to a color, so long as your color names match the member names in System.Drawing.Color.

示例:

string name = "Brown";

颜色c = Color.FromName(name); label1.BackColor = c;

Color c = Color.FromName(name); label1.BackColor = c;
