What are object data types in C#?
The object types can be assigned values of any other types, value types, reference types, predefined or user-defined types. However, before assigning values, it needs type conversion.
The Object Type is the ultimate base class for all data types in C# Common Type System (CTS). Object is an alias for System.Object class.
When a value type is converted to object type, it is called boxing and on the other hand, when an object type is converted to a value type, it is called unboxing.
The following is an example −
object obj; obj = 100; // this is boxing
Here is the complete example showing the usage of object data types −
Example
using System;
using System.IO;
namespace Demo {
class objectClass {
public int x = 200;
}
class MyApplication {
static void Main() {
object obj;
obj = 50;
Console.WriteLine(obj);
Console.WriteLine(obj.GetType());
Console.WriteLine(obj.ToString());
obj = new objectClass();
objectClass newRef;
newRef = (objectClass)obj;
Console.WriteLine(newRef.x);
}
}
}Output
50 System.Int32 50 200
