我想检查一个字符串是否只包含正确的字母.我为此使用了 Char.IsLetter
.我的问题是,当有像 é 或 á 这样的字符时,它们也被认为是正确的字母,这不应该是.
i want to check if a string only contains correct letters.
I used Char.IsLetter
for this.
My problem is, when there are chars like é or á they are also said to be correct letters, which shouldn't be.
是否有可能将字符检查为正确的字母 A-Z 或 a-z 而没有像 á 这样的特殊字母?
is there a possibility to check a char as a correct letter A-Z or a-z without special-letters like á?
bool IsEnglishLetter(char c)
{
return (c>='A' && c<='Z') || (c>='a' && c<='z');
}
您可以将此作为扩展方法:
You can make this an extension method:
static bool IsEnglishLetter(this char c) ...
