问题 With continutation to my earlier thread Using reflection read properties of an object containing array of another object. I am hoping to make this wonderful method from EvgK a generic method that can be used in multiple places in my code base. public static void GetMyProperties(object obj) { List<MyPropertyInfo> oMyProp = new List<MyPropertyInfo>(); foreach (PropertyInfo pinfo in obj.GetType().GetProperties()) { if (!Helper.IsCustomType(pinfo.PropertyType)) { //add properties - name, value,

问题 I'm trying to use Ansible to create two instances, one each in two subnets using the play below. I'm using exact_count with tag Name to keep track of instances. There are two issues here: Ansible ends up creating two instances in the first subnet and reports [ok] for the second subnet. Ansible doesn't seem to care about stopped instances. It creates new instances, instead of starting existing ones, or atleast considering them as part of the group of instances. - name: Create kafka instances

问题 I want the user to enter the name of the object to be used in the code. For example, if I have a class public class Person{ ....... } now instead of me creating an object with a specific name like Person student; I want the user to enter the name for the object maybe like teacher, and then an object teacher of the class person will be created. I do not know if this is even possible in java, many of the solutions I looked up were using a map, but the explanations were not clear enough for me

问题 How do I create a dynamic variable in Javascript? For example, I have: var myAwesomeText = "Hello World!" But now I want the varible MyAesomeText to have a random number attached to it every time the page is refreshed. So it would instead look like something like this: var myAwesomeText12345 = "Hello World!" And most importantly, how do I call that that new random variable back once the random number has been assigned to it? (i.e: alert(???);) I've tried something like this, but I'm going

问题 I am using a mapping file that contains the Entity and the Column Names to perform the insert on so can this be done with entity framework ? The alternative version is just to use inline SQL and write code like sql = INSERT INTO " + someTable + etc.... 回答1: I don't think using Entity Framework (EF) will be a good fit for this project you're working on.

I'm trying to dynamically create the " nutrients" abject by extracting information from a table. "Energy", and all 50 of nutrient names must have a "value" and a "unit" property. Eventually this will be a

问题 Background: I am working with an organization that has an ever-growing collection of data types that they need to extract data from. I have no ability to change these data types. Some are machine-generated from XML files provided by other organizations; some are controlled by intransigent internal dev teams; and some are so old that no one is willing to change them in any way for fear that it will destabilize the entire Earth and cause it to crash into the sun. These classes don't share any
