C# 中的 Decimal.ToInt64() 方法用于将指定的 Decimal 的值转换为等效的 64 位有符号整数。
语法
以下是语法 −
public static long ToInt64 (decimal val);
上面，Val 是要转换的十进制数。
示例
现在让我们看一个实现 Decimal.ToInt64() 方法的示例 −
using System;
public class Demo {
public static void Main(){
Decimal val1 = -567.7989m;
Decimal val2 = 456.000m;
Console.WriteLine("Decimal 1 = "+val1);
Console.WriteLine("Decimal 2 = "+val2);
long res1 = Decimal.ToInt64(val1);
long res2 = Decimal.ToInt64(val2);
Console.WriteLine("64-bit signed integer (value1) (Decimal to signed integer) = "+res1);
Console.WriteLine("64-bit signed integer (value1) (Decimal to signed integer) = "+res2);
}
}
输出
这将产生以下输出 −
Decimal 1 = -567.7989 Decimal 2 = 456.000 64-bit signed integer (value1) (Decimal to signed integer) = -567 64-bit signed integer (value1) (Decimal to signed integer) = 456
示例
现在让我们看另一个实现 Decimal.ToInt64() 方法的示例 −
using System;
public class Demo {
public static void Main(){
Decimal val1 = 1.00m;
Decimal val2 = 34.678m;
Console.WriteLine("Decimal 1 = "+val1);
Console.WriteLine("Decimal 2 = "+val2);
long res1 = Decimal.ToInt64(val1);
long res2 = Decimal.ToInt64(val2);
Console.WriteLine("64-bit signed integer (value1) (Decimal to signed integer) = "+res1);
Console.WriteLine("64-bit signed integer (value1) (Decimal to signed integer) = "+res2);
}
}
输出
这将产生以下输出 −
Decimal 1 = 1.00 Decimal 2 = 34.678 64-bit signed integer (value1) (Decimal to signed integer) = 1 64-bit signed integer (value1) (Decimal to signed integer) = 34
