我在 c# 中有一个字符:
I have a char in c#:
char foo = '2';
现在我想把 2 变成一个 int.我发现 Convert.ToInt32 返回 char 的实际十进制值而不是数字 2.以下将起作用:
Now I want to get the 2 into an int. I find that Convert.ToInt32 returns the actual decimal value of the char and not the number 2. The following will work:
int bar = Convert.ToInt32(new string(foo, 1));
int.parse 也仅适用于字符串.
int.parse only works on strings as well.
C# 中是否没有本地函数可以从 char 转换为 int 而无需将其变为字符串?我知道这是微不足道的,但似乎很奇怪,没有任何东西可以直接进行转换.
Is there no native function in C# to go from a char to int without making it a string? I know this is trivial but it just seems odd that there's nothing native to directly make the conversion.
有趣的答案,但文档的说法不同:
Interesting answers but the docs say differently:
使用 GetNumericValue
方法转换一个 Char
对象,它表示数字到数值类型.利用Parse
和 TryParse
转换一个将字符串中的字符转换为 Char
目的.使用 ToString
转换 Char
对象到 String
对象.
Use the
GetNumericValue
methods to convert aChar
object that represents a number to a numeric value type. UseParse
andTryParse
to convert a character in a string into aChar
object. UseToString
to convert aChar
object to aString
object.
