範例

以下範例透過使用此TimeSpan方法創建多個FromMilliseconds物件。

// Example of the TimeSpan.FromMilliseconds( double ) method.
using System;

class FromMillisecDemo
{
    static void GenTimeSpanFromMillisec( Double millisec )
    {
        // Create a TimeSpan object and TimeSpan string from 
        // a number of milliseconds.
        TimeSpan    interval = TimeSpan.FromMilliseconds( millisec );
        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 += "        ";

        Console.WriteLine( "{0,21}{1,26}", millisec, timeInterval );
    } 

    static void Main( )
    {
        Console.WriteLine(

備註

value參數會轉換成刻數,而該刻數用來初始化新的 TimeSpan。 因此,僅 value 被視為精確到最接近毫秒的精度。 請注意,由於資料型別 Double 精度的損失,此轉換可能產生 OverflowException 一個 ,該值接近但仍在 或 MinValueMaxValue範圍內。 例如,這會導致以下 OverflowException 嘗試實例化物件 TimeSpan

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