C#中的Decimal.Negate()方法
C#中的Decimal.Negate()方法用于返回将指定的Decimal值乘以负1的结果。
语法
以下是语法-
public static decimal Negate (decimal val);
以上，Val是要否定的值。
示例
现在让我们看一个实现Decimal.Negate()方法的示例-
using System;
public class Demo {
public static void Main(){
Decimal val = 3972.491M;
Console.WriteLine("Decimal Value = {0}", val);
Console.WriteLine("HashCode = {0}", (val.GetHashCode()) );
TypeCode type = val.GetTypeCode();
Console.WriteLine("TypeCode = "+type);
Decimal res = Decimal.Negate(val);
Console.WriteLine("Negative (Decimal) = "+res);
}
}输出结果
这将产生以下输出-
Decimal Value = 3972.491 HashCode = 620041307 TypeCode = Decimal Negative (Decimal) = -3972.491
示例
现在让我们来看另一个实现Decimal.Negate()方法的示例-
using System;
public class Demo {
public static void Main(){
Decimal val = -29.35m;
Console.WriteLine("Decimal Value = {0}", val);
Console.WriteLine("HashCode = {0}", (val.GetHashCode()) );
TypeCode type = val.GetTypeCode();
Console.WriteLine("TypeCode = "+type);
Decimal res = Decimal.Negate(val);
Console.WriteLine("Negative (Decimal) = "+res);
}
}输出结果
这将产生以下输出-
Decimal Value = -29.35 HashCode = 1503969289 TypeCode = Decimal Negative (Decimal) = 29.35
