问题 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: Total Time in Nanoseconds: 16,569.8 Total Time in Milliseconds: 16.5698 Average Time Per .GetProperties() Call: 1.65 ns (This is an assumption, not

How do you get the all properties of a class and its base classes (up the hierarchy) with Reflection? (C#)

问题 So what I have right now is something like this: PropertyInfo[] info = obj.GetType().GetProperties(BindingFlags.Public); where obj is some object. The problem is some of the properties I want aren't in obj.GetType() they're in one of the base classes further up. If I stop the debugger and look at obj, the I have to dig through a few "base" entries to see the properties I want to get at. Is there some binding flag I can set to have it return those or do I have to recursively dig through the

Get properties in order of declaration using reflection

问题 I need to get all the properties using reflection in the order in which they are declared in the class. According to MSDN the order can not be guaranteed when using GetProperties() The GetProperties method does not return properties in a particular order, such as alphabetical or declaration order. But I've read that there is a workaround by ordering the properties by the MetadataToken . So my question is, is that safe? I cant seem find any information on MSDN about it. Or is there any other

Reflection - setting Type of returned obj?

问题 I am populating different types objects with datarows with each attrivute of the relevant object = to the similiarly name field in the datarow. I'd like to use a generic function to do this. How do I force the Type of the return object from the generic function. I don't yet know what the <T> syntax actually means: PopulateObject<T> does not return the type as I get compiler error - Cannot implicitly convert type 'object' to 'JobCard' See my code below public JobCard AcceptJobCard(Guid

Big-O of .GetProperties()

问题 If there are n properties, then is the Big-O of .GetProperties O(n) or are there are processes involved in the reflection that add complexity? Say there is this defined class: public class Reflector { public string name { get; set; } public int number { get; set; } public bool flag { get; set; } public List<string> etc { get; set; } } And then this call is made: var reflect = new Reflector(); PropertyInfo[] properties = reflect.GetType().GetProperties(); What is the time complexity, i.e. Big

How to read Android properties with Java

I use 'adb shell getprop' in the terminal. What interfaces can I use in Android JAVA to get the same information? I have tried several things like: Properties sysProps = System.getProperties(); But I don't think these are the same properties I am looking for? Specifically, I want to find values that will return similar to the following: adb shell getprop | grep dolby The shell 'grep dolby' command returns this: [audio.dolby.ds2.enabled]: [true] [dolby.audio.sink.info]: [headset] [dolby.ds.dialogenhancer.state]: [on] [dolby.ds.graphiceq.state]: [off] [dolby.ds.hpvirtualizer.state]: [off] [dolby

问题 I want to check our configuration file and see if it is the same as if I were to create a new configuration file. This method is called GetConfig(). After some hours I noticed that if I save my configuration file and then call GetConfig it works, but if I close the program start it up and load my configuration file in and call GetConfig() it returns my properties in a different order. Below you can see what I mean, property b is an object of a class. There are more than 3 properties, but I
