如何判断角色是大写还是特殊 [英] How do I tell if a character is Capitalized or Special

问题描述

你怎么判断一个角色是：



资本化：ABCDEFGHIJKLMNOPQRSTUVWXYZ



特价：` 〜！@＃$％^&*（）_- + = {[}]：;？/<> | \

How do you tell if a character is:

Capitalized: ABCDEFGHIJKLMNOPQRSTUVWXYZ

Special: `~!@#$%^&*()_-+={[}]:;""?/<>|\

推荐答案

％ ^&*（）_- + = {[}]：;？/<> | \

%^&*()_-+={[}]:;""?/<>|\

要检查大小写，您需要此功能：http://msdn.microsoft.com/en-us/library/system.char.islower(v= vs.110）.aspx [ ^ ]。



另外，要注意fu nctions IsLetter ， IsPunctuation ， IsSeparator 等。使用它们只要有可能。



我真的不确定你只想要列出的字符和这个有限的字符集（为什么？没有这样的概念，特殊性格）。但如果这真的是你需要的，你可以使用

Please see: http://msdn.microsoft.com/en-us/library/system.char%28v=vs.110%29.aspx[^].

To check capitalization, you need this function: http://msdn.microsoft.com/en-us/library/system.char.islower(v=vs.110).aspx[^].

Also, pay attention for the functions IsLetter, IsPunctuation, IsSeparator, etc. Use them whenever possible.

I don't really sure you want only the characters you listed and this limited set of characters (why? there is no such concept, "special character"). But if this is really what you need, you can use

const string myCapitalLetters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
const string myPunctuationCharacters = @"`~!@#

％^& *（）_- + = {[}]：;？/< ;> | \;

// ...

< span class =code-keyword> char characterToTest = // ...某个字符;

// ...

bool isMyCapitalLetter = myCapitalLetters.Contains（characterToTest）;
bool isMyPunctuation = myPunctuationCharacters.Contains（characterToTest）;
// ...

%^&*()_-+={[}]:;""?/<>|\"; // ... char characterToTest = // ... some character; // ... bool isMyCapitalLetter = myCapitalLetters.Contains(characterToTest); bool isMyPunctuation = myPunctuationCharacters.Contains(characterToTest); // ...
