C#Convert.ToInt32(int)方法-将int值转换为int
C＃Convert.ToInt32(int)方法
Convert.ToInt32(int)方法用于将特定的int（有符号整数）值转换为其等效的整数（int32有符号数字）。请注意，int是Int32的别名，因此不执行任何转换。int和Int32都相同。
语法：
int Convert.ToInt32(int value);
它接受一个int值/变量作为参数，并返回其等效的带符号整数。
示例
Input:
int a = -2020;
Output:
-2020
Input:
int a = 1278387;
Output:
1278387码：
using System;
using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
int a = 10;
int b = -2020;
int c = 1278387;
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: 10, type of a: System.Int32 value of b: -2020, type of b: System.Int32 value of c: 1278387, type of c: System.Int32 value: 10, type: System.Int32 value: -2020, type: System.Int32 value: 1278387, type: System.Int32
