// Call a method on the instance ((MyClass)instance).MyMethod(); } }
: Creating instances of a generic type parameter T when the new() constraint isn't applicable or more flexibility is needed. c# activator
public class MyClass { public MyClass(string name, int age) { Console.WriteLine($"MyClass constructor called with name {name} and age {age}"); } // Call a method on the instance ((MyClass)instance)
Common exceptions include TypeLoadException , MissingMethodException (if no matching constructor is found), and TargetInvocationException (if the constructor itself throws an exception). Robust error handling is mandatory when using the Activator . A developer must wrap dynamic instantiation in try-catch blocks or validate the type information rigorously before attempting creation to prevent application crashes. A developer must wrap dynamic instantiation in try-catch
class Program { static void Main(string[] args) { // Get the type of MyClass Type type = typeof(MyClass);
// Create an instance of MyClass using Activator.CreateInstance, passing arguments to the constructor object instance = Activator.CreateInstance(type, new object[] { "John Doe", 30 });
class Program { static void Main(string[] args) { // Get the type of MyClass Type type = typeof(MyClass);
