C＃Convert.ToInt32(long)方法 (C# Convert.ToInt32(long) Method)

Convert.ToInt32(long) Method is used to convert a specific 64-bit signed integer (long) value to its equivalent 32-bits signed integer (int32).

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)。

Note: Value to be converted should not exceed the range of a signed 32-bit integer.

注意：要转换的值不应超过带符号的32位整数的范围。

Syntax:

句法：

    int Convert.ToInt32(long value);

It accepts a long value/variable as an argument and returns its equivalent signed integer.

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。

Example:

例：

    Input:
int a = 1234567;
Output:
1234567
Input:
int a = - 7654321;
Output:
-7654321

Code:

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());
//hit ENTER to exit
Console.ReadLine();
}
}
}

Output

输出量

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
