示例

以下示例使用 FromMinutes 方法创建多个 TimeSpan 对象。

// Example of the TimeSpan::FromMinutes( double ) method.
using namespace System;
void GenTimeSpanFromMinutes( double minutes )
{
   
   // Create a TimeSpan object and TimeSpan string from 
   // a number of minutes.
   TimeSpan interval = TimeSpan::FromMinutes( minutes );
   String^ timeInterval = interval.ToString();
   
   // Pad the end of the TimeSpan string with spaces if it 
   // does not contain milliseconds.
   int pIndex = timeInterval->IndexOf( ':' );
   pIndex = timeInterval->IndexOf( '.', pIndex );
   if ( pIndex < 0 )
      timeInterval = String::Concat( timeInterval, "        " );

   Console::WriteLine( "{0,21}{1,26}", minutes, timeInterval );
}

int main()
{
   Console::WriteLine( "This example of TimeSpan::FromMinutes( double )\n"
   "generates the following output.\n" );
   Console::WriteLine( "{0,21}{1,18}", "FromMinutes", "TimeSpan" );
   Console::WriteLine( "{0,21}{1,18}", "-----------", "--------" );
   GenTimeSpanFromMinutes( 0.00001 );
   GenTimeSpanFromMinutes( 0.00002 );
   GenTimeSpanFromMinutes( 0.12345 );
   GenTimeSpanFromMinutes( 1234.56789 );
   GenTimeSpanFromMinutes( 12345678.98765 );
   GenTimeSpanFromMinutes( 0.01666 );
   GenTimeSpanFromMinutes( 1 );
   GenTimeSpanFromMinutes( 60 );
   GenTimeSpanFromMinutes( 1440 );
   GenTimeSpanFromMinutes( 30020.33667 );

注解

value 参数转换为毫秒,该毫秒转换为时钟周期,并且该时钟周期数用于初始化新的 TimeSpan。 因此,value 仅被视为最接近毫秒的准确值。 请注意,由于 Double 数据类型的精度损失,此转换可以为接近但仍处于 MinValueMaxValue范围内的值生成 OverflowException。 例如,这会导致以下尝试实例化 TimeSpan 对象 OverflowException

// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMinutes(TimeSpan.MaxValue.TotalMinutes);
// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromMinutes TimeSpan.MaxValue.TotalMinutes
' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromMinutes(TimeSpan.MaxValue.TotalMinutes)
