Provides access to factory methods for creating instances of the specified generic type parameter.

ActivatorFactory

Examples

The following example shows how to create instances of types at runtime using ActivatorFactory. It creates a StringBuilder with no arguments and a DateTime with constructor arguments, then prints each result.

using System;
using System.Text;
using Cuemon.Reflection;

namespace Cuemon.Reflection;

public class ActivatorFactoryExample
{
    public void Demonstrate()
    {
        var sb = ActivatorFactory.CreateInstance<StringBuilder>();
        sb.Append("Hello from activator");
        Console.WriteLine(sb.ToString());

        var dt = ActivatorFactory.CreateInstance<int, int, int, DateTime>(2025, 12, 1);
        Console.WriteLine($"Created: {dt:yyyy-MM-dd}");
    }
}
