如何从C#中的字符串创建泛型类？

using System;
using System.Reflection;

public class GenericClass<T>
{
    public T Value { get; set; }
}

public class Program
{
    public static void Main()
    {
        string typeName = "GenericClass";
        Type genericType = Type.GetType(typeName);

        Type constructedType = genericType.MakeGenericType(typeof(string));
        object instance = Activator.CreateInstance(constructedType);

        PropertyInfo valueProperty = constructedType.GetProperty("Value");
        valueProperty.SetValue(instance, "Hello, World!");

        Console.WriteLine(((GenericClass<string>)instance).Value);
    }
}
