Get list of properties from List of objects

Currently I use foreach loop to return a list of object properties.

 class X
 {
     List<X> Z = GetXlist();
     List<String> r = new List<String>();

     foreach (var z in Z)
     {
         r.Add(z.A);
     }

     return r;
}

Is there a way that I can shorten this so that I don't have to write the foreach loop?

LINQ is the answer. You can use it to "project" from your object collection to another collection - in this case a collection of object property values.

List<string> properties = objectList.Select(o => o.StringProperty).ToList();

C#: How to convert a list of objects to a list of a single property of that , List<string> firstNames = people.Select(person => person.FirstName).ToList();. And with sorting. List<string> orderedNames = people. But neither would work for the objects that need additional module to get access to. For example, piping the Get-ADComputer cmdlet to Get-Member or Format-List only gets a small subset of properties of an AD computer object. Get-ADComputer -Filter * | Get-Member. Instead, use this to get the full list of properties with values. Get-AdComputer

You could use LINQ:

List<X> Z = GetXlist();

List<String> r = Z.Select(z => z.A).ToList();

return r;

Or just,

return GetXlist().Select(z => z.A).ToList();

Find out more about LINQ. It is pretty useful.

Different Ways of Creating a List of Objects in C#, In this post, we will see how we can create a list of objects with a different approach. The scenario is: for First, let's create one basic POCO class - Book - with some properties: public string Author { get; set; } = string.Empty;. Re: How to get the complete list of objects's properties Hey you are very fast - before I saw you reply I found out that, sorry. Could the code be changed to be possible to select more solids and export such a list of dimensions into an external file or access it for copying (like _dist or _massprop command)??

List properties = objectList.Select(o => o.StringProperty).ToList();

You Also Can Do By Private OverLoading Method and Use That in LINQ Query.

List<T>.Count Property, Gets the number of elements contained in the List<T>. public int Count { get; } Equals(object obj) { if (obj == null) return false; Part objAsPart = obj as Part;  Object properties tell us about the object. Every time you run a “Get-” PowerShell cmdlet, you receive a single object or set of objects. In the programming world, an object’s properties are attributes about the object itself. A property could be a text string, a number, a timestamp, or any other descriptive value.

C# List - How to C# List - CSharp, Generic namespace and it provides the methods and properties like other Collection classes The C# List < T > class represents a strongly typed list of objects that can be How to get duplicate items from a list using LINQ. And the person object has properties like FirstName, LastName, and Gender. How can I convert this to a list of properties of the Person object. For example, to a list of first names.

C# List<T>, Hence, the List<T> object can be assigned to any of its interface type variables. However Use the Count property to get the total number of elements in the List. As slashnick pointed out, you can use the "for in" construct to iterate over an object for its attribute names. However you'll be iterating over all attribute names in the object's prototype chain. If you want to iterate only over the object's own attributes, you can make use of the Object#hasOwnProperty () method. Thus having the following.

Object.values(), The object whose enumerable own property values are to be returned. Return value. An array containing the given object's own enumerable  There's also a show-object command in the PowerShellCookbook module that does it in a GUI. Jeffrey Snover, the PowerShell creator, uses it in his unplugged videos (recommended). Although most often I use. Get-WmiObject Win32_computersystem | fl * It avoids the .format.ps1xml file that defines a table or list view for the object type, if there are any.
