此方法用于将该实例的值转换为等效的OLE自动化日期。
用法: public double ToOADate ();
返回值:此方法返回一个双精度浮点数,其中包含与该实例的值相等的OLE自动化日期。
异常:
OverflowException:如果此实例的值不能表示为OLE自动化日期。
以下示例程序旨在说明DateTime.ToOADate()方法的使用
示例1:
// C# program to demonstrate the
// DateTime.ToOADate() Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of DateTime
DateTime date = new DateTime(2011, 1,
1, 4, 0, 15);
// Converts the value of this instance to
// the equivalent OLE Automation date.
// using ToOADate() method;
double value = date.ToOADate();
// Display the time
Console.WriteLine("OLE Automation date is {0}", value);
}
catch (OverflowException e) {
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
输出:
OLE Automation date is 40544.1668402778
示例2:对于OverflowException
// C# program to demonstrate the
// DateTime.ToOADate() Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of DateTime
DateTime date = new DateTime(0099, 1,
1, 4, 0, 15);
// Converts the value of this instance
// to the equivalent OLE Automation date.
// using ToOADate() method;
double value = date.ToOADate();
// Display the time
Console.WriteLine("OLE Automation date is {0}", value);
}
catch (OverflowException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
输出:
Exception Thrown: System.OverflowException
