I have a date-time variable like this:
DateTime myDate=DateTime.Now; // result is like this: 8/2/2020 12:54:07 PM
and I want to get myDate variable like this
DateTime getOnlyDate=myDate.Date;
and I want to get myDate.Date; with reflection
how can I get Date property value with reflection?
with reflection I do something like this:
PropertyInfo myDate = typeof(DateTime).GetProperty("Date");
but I don`t know how can I request myDate.Date; value with reflection.
thanks in advance
Once you've retrieved the PropertyInfo, you fetch the value with PropertyInfo.GetValue, passing in "the thing you want to get the property from" (or null for a static property).
Here's an example:
using System;
using System.Reflection;
class Program
{
static void Main()
{
DateTime utcNow = DateTime.UtcNow;
PropertyInfo dateProperty = typeof(DateTime).GetProperty("Date");
PropertyInfo utcNowProperty = typeof(DateTime).GetProperty("UtcNow");
// For instance properties, pass in the instance you want to
// fetch the value from. (In this case, the DateTime will be boxed.)
DateTime date = (DateTime) dateProperty.GetValue(utcNow);
Console.WriteLine($"Date: {date}");
// For static properties, pass in null - there's no instance
// involved.
DateTime utcNowFromReflection = (DateTime) utcNowProperty.GetValue(null);
Console.WriteLine($"Now: {utcNowFromReflection}");
}
}
myDate.GetValue(myDate);myDatecan't simultaneously be aPropertyInfoand aDateTime. I realize that's a problem in the OP's code, but it would be better not to propagate it into a comment.
