C#Convert.ToInt32(decimal)方法-将十进制值转换为int
C＃Convert.ToInt32（十进制）方法
Convert.ToInt32(decimal)方法用于将特定的十进制值（可以包含带小数部分或不带小数的数字）转换为其等效的整数（32位带符号的整数）。
语法：
int Convert.ToInt32(decimal value);
它接受一个十进制值/变量作为参数，并返回其等效的带符号整数。
示例
Input:
decimal a = 1023.12m;
Output:
1023
Input:
decimal a = 1023.56m;
Output:
1024码：
using System;
using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
decimal a = 1023;
decimal b = 1023.56m;
decimal c = 1023.12m;
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: 1023, type of a: System.Decimal value of b: 1023.56, type of b: System.Decimal value of c: 1023.12, type of c: System.Decimal value: 1023, type: System.Int32 value: 1024, type: System.Int32 value: 1023, type: System.Int32
