DateTimeOffset.CompareTo(DateTimeOffset)方法用于将当前DateTimeOffset对象与指定的DateTimeOffset对象进行比较，并指示当前对象是早于，相同还是晚于第二个DateTimeOffset对象。
用法： public int CompareTo (DateTimeOffset other);
Here, it takes an object to compare with the current DateTimeOffset object.
返回值：此方法返回一个有符号整数，该整数指示当前DateTimeOffset对象与其他对象之间的关系。
- 小于零：表示当前的DateTimeOffset对象早于其他对象。
- 零：表示当前的DateTimeOffset对象与其他对象相同。
- 大于零：表示当前的DateTimeOffset对象晚于其他对象。
以下示例程序旨在说明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");
}
}
}
输出：
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");
}
}
}
输出：
offset1 is equal to offset2
