如何从注册表中读取颜色？ [英] How to read a color from registry?

问题描述

将颜色对象保存到注册表会将其值设置为类似

颜色[红色]或颜色[A = 255，R = 123，G] = 234，B = 231]"，

但如何将其重新放回Color对象???


将其转换为Color只会导致一个例外。

Saving a color object to registry will set it''s value to something like
"Color [Red]", or "Color [A=255, R=123, G=234, B=231]",
but how do I get this back into a Color object???

Casting it to Color only causes an exception.

在HKEY_Current_User \Software \ ColorTest中创建一个注册表条目


Color testColor = Color.FromArgb（123,234,75）;

RegistryKey regKey =

Registry.CurrentUser.CreateSubKey（" Software \\ Color Test"）;

regKey.SetValue（" Color"，testColor）;

regKey.Close（）;


要阅读它我想要的使用像
这样的东西/>
RegistryKey colorKey =

Registry.CurrentUser.OpenSubKey（" Software \\ColorTe st"）;

颜色regColor =（颜色）regKey .GetValue（QUOT;颜色"）; //这不起作用

colorKey.Close（）;


我可以通过将颜色转换为int并从
int，但我更喜欢在注册表中保持颜色可读。

To make a registry entry in HKEY_Current_User\Software\ColorTest

Color testColor = Color.FromArgb(123, 234, 75);
RegistryKey regKey =
Registry.CurrentUser.CreateSubKey("Software\\Color Test");
regKey.SetValue("Color", testColor);
regKey.Close();

To read it I would want to use something like

RegistryKey colorKey =
Registry.CurrentUser.OpenSubKey("Software\\ColorTe st");
Color regColor = (Color)regKey.GetValue("Color"); // this does not work
colorKey.Close();

I can do it by translating the color to int and creating a new color from
int, but I would prefer to keep the color readable in registry.

啊，那是因为你将ToString（）方法的结果保存到

注册表中。不幸的是，没有简单的方法将它转换回Color

~除了检查字符串之外 - 绝对不能把它转换为

颜色因为它是一个字符串！


最好将调用ToArgb（）的结果保存到注册表中。当

你加载int值并需要从

实例化一个Color对象时，你可以说：


颜色col = Color.FromArgb（<把注册表中的int放在这里>）;

Ah, that''s because you''re saving the result of ToString() method to the
registry. Unfortunately, there''s no easy way to convert it back to Color
~ other than examining the string--and definitely you can''t cast it to
Color because it''s a string!

It''s better to save the result of calling ToArgb() to the registry. When
you load the int value back and need to instantiate a Color object from
that, you can just say:

Color col = Color.FromArgb(<put the int from the Registry here>);
