C#Convert.ToInt32(object)方法-将对象值转换为int
C＃Convert.ToInt32(object)方法
Convert.ToInt32(object)方法用于将特定对象的值转换为其等效的32位带符号整数(int32)。
注意：要转换的对象的值不应超过有符号的32位整数的范围，即，通过函数转换的值应与32位的有符号整数的范围匹配。
语法：
int Convert.ToInt32(object value);
它接受一个对象值/变量作为参数，并返回其等效的带符号整数。
示例
Input:
object a = 'A';
Output:
65
Input:
object a = 10.23m;
Output:
10码：
using System;
using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
object a = 'A'; //字符对象
object b = 10.23f; //单/浮式对象
object c = 10.23m; //小数对象
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());
Console.WriteLine("value of c: {0}, type of c: {1}", c, c.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());
Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(c), Convert.ToInt32(c).GetType());
//按ENTER退出
Console.ReadLine();
}
}
}输出结果
value of a: A, type of a: System.Char value of b: 10.23, type of b: System.Single value of c: 10.23, type of c: System.Decimal value: 65, type: System.Int32 value: 10, type: System.Int32 value: 10, type: System.Int32
