C#char to int [英] C# char to int
问题描述
所以我在c#中有一个char:
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.以下将工作:
int bar = Convert.ToInt32(new string(foo,1));
int.parse仅适用于字符串。
在C#中没有本地函数从char到int而不是字符串?我知道这是微不足道的,但它似乎很奇怪,没有原生的直接进行转换。
有趣的答案,换句话说:
使用GetNumericValue方法
将表示
a数字的Char对象转换为数值类型。使用
Parse和TryParse将字符串中的
字符转换为Char
对象。使用ToString将Char
对象转换为String对象。

So I have a char in c#:
char foo = '2';
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 only works on strings as well.
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.
Interesting answers but the docs say differently:
Use the GetNumericValue methods to convert a Char object that represents a number to a numeric value type. Use Parse and TryParse to convert a character in a string into a Char object. Use ToString to convert a Char object to a String object.
