Get List Object Properties and Values using Reflection in C#, VB.NET

Introduction:

Here we will learn how to use reflection to get list object properties and values in c#, vb.net with example or get all properties and values of an object in c#, vb.net with example or get list of properties from list of objects using reflection in c#, vb.net or how to get property names and values using reflection in c#, vb.net with example. By using Reflection properties we can easily get list object property names and values based on our requirements.

Description:

In previous articles I explained send generic list as parameter to function in c#, convert list object to json string in c#, vb.net, bind generic list to gridview example in asp.net, jQuery bind data to asp.net gridview example, dictionary object in c#, vb.net with example, static constructor in c#, vb.net with example, difference between ref and out in c#, vb.net with example and many more articles related to generic list, asp.net, mvc, c#, vb.net. Now I will explain how to get all property names and values of an object in c#, vb.net with example.

By using Reflection properties (PropertiesInfo) we can easily get list object property names and values based on our requirements.

Following is the simple code snippet to get all the property names and values of an object in c#, vb.net.

C# Code

Type type = user.GetType(); PropertyInfo[] props = type.GetProperties(); string str = "{"; foreach (var prop in props) { str+= (prop.Name+":"+  prop.GetValue(user))+","; } return str.Remove(str.Length-1)+"}";

VB.NET Code

Dim type As Type = user.[GetType]() Dim props() As PropertyInfo = type.GetProperties() Dim str As String = "{" For Each prop In props str += (prop.Name + ":" + CStr(prop.GetValue(user))) + "," Next Return str.Remove(str.Length - 1) + "}"

If you want complete example to get all the properties and values of an object write the code like as shown following.

C# Code

using System; using System.Collections.Generic; using System.Reflection; namespace SampleConsoleApp { class Program { static void Main(string[] args) { List<userdetails> items = new List<userdetails>(); items.Add(new userdetails { userid = 1, username = "suresh", location = "chennai" }); items.Add(new userdetails { userid = 2, username = "rohini", location = "guntur" }); items.Add(new userdetails { userid = 3, username = "praveen", location = "bangalore" }); items.Add(new userdetails { userid = 4, username = "sateesh", location = "vizag" }); items.Add(new userdetails { userid = 5, username = "madhav", location = "nagpur" }); items.Add(new userdetails { userid = 6, username = "honey", location = "nagpur" }); string strmsg = string.Empty; foreach (var user in items) { strmsg = GetPropertyValues(user); Console.WriteLine(strmsg); } Console.ReadLine(); } private static string GetPropertyValues(userdetails user) { Type type = user.GetType(); PropertyInfo[] props = type.GetProperties(); string str = "{"; foreach (var prop in props) { str+= (prop.Name+":"+  prop.GetValue(user))+","; } return str.Remove(str.Length-1)+"}"; } } class userdetails { public int userid { get; set; } public string username { get; set; } public string location { get; set; } } }

VB.NET Code

Imports System.Reflection Module Module1 Sub Main() Dim items As New List(Of userdetails)() Dim user As New userdetails() items.Add(New userdetails() With { .userid = 1, .username = "suresh", .location = "chennai" }) items.Add(New userdetails() With { .userid = 2, .username = "rohini", .location = "guntur" }) items.Add(New userdetails() With { .userid = 3, .username = "praveen", .location = "bangalore" }) items.Add(New userdetails() With { .userid = 4, .username = "sateesh", .location = "vizag" }) items.Add(New userdetails() With { .userid = 5, .username = "madhav", .location = "nagpur" }) items.Add(New userdetails() With { .userid = 6, .username = "honey", .location = "nagpur" }) Dim strmsg As String = String.Empty For Each user In items strmsg = GetPropertyValues(user) Console.WriteLine(strmsg) Next Console.ReadLine() End Sub Private Function GetPropertyValues(user As userdetails) As String Dim type As Type = user.[GetType]() Dim props() As PropertyInfo = type.GetProperties() Dim str As String = "{" For Each prop In props str += (prop.Name + ":" + CStr(prop.GetValue(user))) + "," Next Return str.Remove(str.Length - 1) + "}" End Function Class userdetails Public Property userid() As Integer Get Return m_userid End Get Set m_userid = Value End Set End Property Private m_userid As Integer Public Property username() As String Get Return m_username End Get Set m_username = Value End Set End Property Private m_username As String Public Property location() As String Get Return m_location End Get Set m_location = Value End Set End Property Private m_location As String End Class End Module

If you observe above code we added namespace “System.Reflection” to get properties and values of an object using PropertyInfo property.

Demo

When we run above code we will get result like as shown below

This is how we can access all the property names and values of an object based on our requirements.
