C#Convert.ToInt32(long)方法-将long值转换为int
C＃Convert.ToInt32(long)方法
Convert.ToInt32(long)方法用于将特定的64位带符号整数(long)值转换为其等效的32位带符号整数(int32)。
注意：要转换的值不应超过带符号的32位整数的范围。
语法：
int Convert.ToInt32(long value);
它接受一个长值/变量作为参数，并返回其等效的带符号整数。
示例
Input:
int a = 1234567;
Output:
1234567
Input:
int a = - 7654321;
Output:
-7654321码：
using System;
using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
long a = 1234567;
long b = -7654321;
long c = 47878330;
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: 1234567, type of a: System.Int64 value of b: -7654321, type of b: System.Int64 value of c: 47878330, type of c: System.Int64 value: 1234567, type: System.Int32 value: -7654321, type: System.Int32 value: 47878330, type: System.Int32
