Some characters in C# are numeric Unicode. We can get the numeric values of these characters by using the Char.GetNumericValue() method. Numeric Unicode characters are present in strings. These characters are the numbers we know. Some examples of these characters are 1, 2, 3, and so on. These numbers are referred to as characters when they are used inside strings.
When we create a string that has numeric Unicode character(s), we can get the numeric value of any of those characters by using the Char.GetNumericValue() method and specifying the index position of the character.
public static double GetNumericValue (string s, int index);
s: This is the string that calls this method.
index: This is the index position of the character, in the string, whose numeric value we want to get.
The value returned is a double value.
In the code below, we will create some strings and get the numeric values of some of their characters, using the Char.GetNumericValue() method.
Note: If the character at position
indexis not a numeric character,-1is returned.
