返回一个新的 DateTime，它将指定的分钟数加到此实例的值上。

public:
 DateTime AddMinutes(double value);

public DateTime AddMinutes (double value);

member this.AddMinutes : double -> DateTime

Public Function AddMinutes (value As Double) As DateTime

参数

value: Double

由整数和小数部分组成的分钟数。 value 参数可以是负数也可以是正数。

DateTime

一个对象，其值是此实例所表示的日期和时间与 value 所表示的分钟数之和。

例外

ArgumentOutOfRangeException

生成的 DateTime 小于 DateTime.MinValue 或大于 DateTime.MaxValue。

示例

以下示例使用 AddMinutes 方法将一些整数和小数值添加到日期和时间。

using namespace System;

void main()
{
   DateTime dateValue(2013, 9, 15, 12, 0, 0);
   
   array<Double>^ minutes = { .01667, .08333, .16667, .25, .33333, 
                              .5, .66667, 1, 2, 15, 30, 17, 45, 
                              60, 180, 60 * 24 };
   
   for each (Double minute in minutes)
      Console::WriteLine("{0} + {1} minute(s) = {2}", dateValue, minute, 
                         dateValue.AddMinutes(minute));
}

注解

此方法不会更改此 DateTime的值。相反，它返回一个新的 DateTime ，其值是此操作的结果。

的小数部分 value 是一分钟的小数部分。例如，4.5 相当于 4 分钟、30 秒、0 毫秒和 0 个刻度。

在 .NET 6 及更早版本中， value 参数四舍五入为最接近的毫秒。在 .NET 7 及更高版本中，将使用参数的完整Doublevalue精度。但是，由于浮点数学固有的不精确性，生成的精度将有所不同。
