Yes it is possible to overwrite ToString method:
Step 1: Declare a ToString method with the following modifiers and return type:
public override string ToString(){}
Step 2: Implement the method so that it returns a string. The following example returns the name of the class in addition to the data specific to a particular instance of the class.
class Person
{
public string Name { get; set; }
public int Age { get; set; }
public override string ToString()
{
return "Person: " + Name + " " + Age;
}
}
