Introduction
ExpandoObject it like a expand property in HTML. Microsoft introduces new class
ExpandoObject. It's really dynamic object. It is part of DLR (dynamic language
runtime).
The ExpandoObject class enables you to add and delete members of its instances
at run time and also to set and get values of these members. This class supports
dynamic binding, which enables you to use standard syntax like
sampleObject.sampleMember instead of more complex syntax like
sampleObject.GetAttribute("sampleMember").

Purpose: To create a runtime instance of any type. You can add
properties, methods, and events to instances of the ExpandoObject class.
Code
Here we are creating dynamic instance.
dynamic
Employee = new ExpandoObject();
Employee.ID = 1;
Employee.Name = "Amit";
Employee.Salary = 10000;
Nested dynamic instance
Employee.Addess = new ExpandoObject();
Employee.Addess.City = "Pune";
Employee.Addess.Country = "India";
Employee.Addess.PinCode = 456123;
Bind dynamic Event
Employee.Click += new EventHandler(SampleHandler);
private void
SampleHandler(object
sender, EventArgs
e)
{
//throw new NotImplementedException();
}
Pass
parameter as dynamic.
public void
Write(dynamic
employee)
{
//you can write your logic
}
Happy coding
