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:
GetNumericValuemethods to convert a
Charobject that represents a number to a numeric value type. Use
TryParseto convert a character in a string into a
ToStringto convert a
Charobject to a
This will convert it to an int:
char foo = '2'; int bar = foo - '0';
This works because each character is internally represented by a number. The characters '0' to '9' are represented by consecutive numbers, so finding the difference between the characters '0' and '2' results in the number 2.
