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 );

注解
参数 value
转换为毫秒,转换为刻度数,并且该刻度数用于初始化新的 TimeSpan。 因此, value
将仅被视为精确到最接近的毫秒。 请注意,由于数据类型的精度Double丢失,此转换可能会为接近但仍在 或 MaxValue范围内的MinValue值生成 OverflowException 。 例如,这会导致 OverflowException 在以下尝试中实例化对象 TimeSpan 。
// 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)
