C＃Convert.ToInt32(char)方法 (C# Convert.ToInt32(char) Method)
Convert.ToInt32(char) Method is used to convert a specific char value to its equivalent integer (int 32 signed number) (It can also be known as ASCII value).
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)。
Syntax:
句法：
int Convert.ToInt32(char value);
It accepts a char value/variable as an argument and returns its equivalent signed integer.
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。
Example:
例：
Input:
char a = 'A';
Output:
65
Code:
码：
using System;
using System.Text;
namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
char a = 'A'; //uppercase A
char b = 'z'; //lowercase 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());
//hit ENTER to exit
Console.ReadLine();
}
}
}
Output
输出量
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
