The object type is an alias for System.Object in the .NET Framework. You can assign values of any type to variables of type object.
All data types, predefined and user-defined, inherit from the System.Object class. The object data type is the type to and from which objects are boxed.
Example
The following sample shows how variables of type object can accept values of any data type and how variables of type object can use methods on System.Object from the .NET Framework.
// keyword_object.cs
using System;
public class MyClass1
{
public int i = 10;
}
public class MyClass2
{
public static void Main()
{
object a;
a = 1; // an example of boxing
Console.WriteLine(a);
Console.WriteLine(a.GetType());
Console.WriteLine(a.ToString());
Console.WriteLine();
a = new MyClass1 ();
MyClass1 ref_MyClass1;
ref_MyClass1 = (MyClass1)a;
Console.WriteLine(ref_MyClass1.i);
}
}Output
