如何使用C#中的变量调用对象的属性,例如customer.&fieldName

using System;

public class Customer
{
    public string Name { get; set; }
    public int Age { get; set; }
}

public class Program
{
    public static void Main()
    {
        Customer customer = new Customer { Name = "John", Age = 30 };
        string fieldName = "Name";

        Type customerType = customer.GetType();
        PropertyInfo propertyInfo = customerType.GetProperty(fieldName);
        object value = propertyInfo.GetValue(customer, null);

        Console.WriteLine($"The value of {fieldName} is {value}");
    }
}
