Convert.ToInt32(char)方法用于将特定的char值转换为其等效的整数(int 32带符号的数字)(也称为ASCII值)。
语法:
int Convert.ToInt32(char value);
它接受一个char值/变量作为参数,并返回其等效的带符号整数。
示例
Input: char a = 'A'; Output: 65
码:
using System; using System.Text; namespace ConsoleApplication3 { class Program { static void Main(string[] args) { char a = 'A'; //大写A char b = 'z'; //小写字母z Console.WriteLine("value of a: {0}, type of a: {1}", a, a.GetType()); Console.WriteLine("value of b: {0}, type of b: {1}", b, b.GetType()); //converting to Int32 & printing values & types Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(a), Convert.ToInt32(a).GetType()); Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(b), Convert.ToInt32(b).GetType()); //按ENTER退出 Console.ReadLine(); } } }
输出结果
value of a: A, type of a: System.Char value of b: z, type of b: System.Char value: 65, type: System.Int32 value: 122, type: System.Int32
