Therefore, if your Java code uses index starting from 1, you need to subtract 1 from the index in your C# code.//n//nThis method accepts a character and an index as parameters. If the character is a digit, it returns the integer value of that digit. If the character is a letter, it returns the corresponding hexadecimal value of the letter. If the character is neither a digit nor a letter, it throws an argument exception.//n//nHope this helps!//n/
