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
