Question

I have a class.

Public Class Foo     Private _Name As String     Public Property Name() As String         Get             Return _Name         End Get         Set(ByVal value As String)             _Name = value         End Set     End Property      Private _Age As String     Public Property Age() As String         Get             Return _Age         End Get         Set(ByVal value As String)             _Age = value         End Set     End Property      Private _ContactNumber As String     Public Property ContactNumber() As String         Get             Return _ContactNumber         End Get         Set(ByVal value As String)             _ContactNumber = value         End Set     End Property   End Class 

I want to loop through the properties of the above class. eg;

Public Sub DisplayAll(ByVal Someobject As Foo)     For Each _Property As something In Someobject.Properties         Console.WriteLine(_Property.Name & '=' & _Property.value)     Next End Sub

Use Reflection:

Type type = obj.GetType(); PropertyInfo[] properties = type.GetProperties();  foreach (PropertyInfo property in properties) {     Console.WriteLine('Name: ' + property.Name + ', Value: ' + property.GetValue(obj, null)); } 

for Excel – what tools/reference item must be added to gain access to BindingFlags, as there is no ‘System.Reflection’ entry in the list

Edit: You can also specify a BindingFlags value to type.GetProperties():

BindingFlags flags = BindingFlags.Public | BindingFlags.Instance; PropertyInfo[] properties = type.GetProperties(flags); 

That will restrict the returned properties to public instance properties (excluding static properties, protected properties, etc).

You don’t need to specify BindingFlags.GetProperty, you use that when calling type.InvokeMember() to get the value of a property.
