In relation to: Big-O of .GetProperties()
How many nanoseconds does the .GetProperties()
method take in C#?
EDIT
Tested:
On simple dev computer (nothing fancy), item has 8 properties, and no inheritance:
stopwatch.Start();
for (int i = 0; i < 10000; i++)
{
PropertyInfo[] properties = item.GetType().GetProperties();
}
stopwatch.Stop();
Results:
Moreover
When ran a second time with an extra nested foreach loop this only took a total of 6 milliseconds. Here is the added code (inside the for loop):
foreach (var prop in properties)
{
var x = prop;
}
Given your complete application code, a complete description of your hardware, your registry or system configuration, your operating system version, and a list of all running software and their activities, it should be possible to come up with a reasonable guess.
What I am trying to say is that it depends. On almost everything. The only way to find out is to time it, preferably with a
Stopwatch
and over many iterations. The exact result varies from time to time, and is mostly dependent on the class that you are examining, the amount of CPU power available, and luck (aka processor scheduling).
