DateTimeOffset.CompareTo(DateTimeOffset)方法用於將當前DateTimeOffset對象與指定的DateTimeOffset對象進行比較，並指示當前對象是早於，相同還是晚於第二個DateTimeOffset對象。
用法： public int CompareTo (DateTimeOffset other);
Here, it takes an object to compare with the current DateTimeOffset object.
返回值：此方法返回一個有符號整數，該整數指示當前DateTimeOffset對象與其他對象之間的關係。
- 小於零：表示當前的DateTimeOffset對象早於其他對象。
- 零：表示當前的DateTimeOffset對象與其他對象相同。
- 大於零：表示當前的DateTimeOffset對象晚於其他對象。
以下示例程序旨在說明DateTimeOffset.CompareTo(DateTimeOffset)方法的用法：
示例1:
// C# program to demonstrate the
// DateTimeOffset.CompareTo(DateTimeOffset)
// Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// creating object of DateTimeOffset
DateTimeOffset offset1 = new DateTimeOffset(2007,
6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0));
// creating object of DateTimeOffset
DateTimeOffset offset2 = new DateTimeOffset(2006,
6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0));
// comparing two offset1 and offset2
// instance using CompareTo() method
int value = offset1.CompareTo(offset2);
if (value > 0)
{
Console.Write("offset1 is later than offset2 ");
}
else if (value < 0)
{
Console.Write("offset1 is earlier than offset2");
}
else
{
Console.Write("offset1 is equal to offset2");
}
}
}
輸出：
offset1 is later than offset2
示例2:
// C# program to demonstrate the
// DateTimeOffset.CompareTo(DateTimeOffset)
// Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// creating object of DateTimeOffset
DateTimeOffset offset1 = new DateTimeOffset(2006,
6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0));
// creating object of DateTimeOffset
DateTimeOffset offset2 = new DateTimeOffset(2006,
6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0));
// comparing two offset1 and offset2
// instance using CompareTo() method
int value = offset1.CompareTo(offset2);
if (value > 0)
{
Console.Write("offset1 is later than offset2 ");
}
else if (value < 0)
{
Console.Write("offset1 is earlier than offset2");
}
else
{
Console.Write("offset1 is equal to offset2");
}
}
}
輸出：
offset1 is equal to offset2
