How Can I Dynamically Access Property Values in C# Using Reflection?

Obtaining Property Values Dynamically Based on Property Names

When working with objects and manipulating their properties, a common requirement is the ability to retrieve or set the value of a specific property dynamically based on its name. This enables flexibility and code reusability in various scenarios.

Dynamic Property Value Retrieval

In C#, reflection can be used to achieve this functionality. Here's an example implementation of a method that can obtain the value of a property based on its name:

public string GetPropertyValue(object obj, string propertyName)
{
    return obj.GetType().GetProperty(propertyName).GetValue(obj, null);
}

This method takes an object and the name of the property as arguments. It uses reflection to retrieve the PropertyInfo object associated with the specified property name. The GetValue method of the PropertyInfo object is then used to obtain the actual value of the property for the given object.

Usage:

To use this method, you simply provide an object and the property name you want to retrieve the value for. For instance:

var car = new Car { Make = "Ford" };
string make = GetPropertyValue(car, "Make");

In this example, the GetPropertyValue method is used to retrieve the value of the Make property of the car object. The result will be assigned to the make variable, which will hold the value "Ford".

This approach offers a versatile and dynamic way to access property values, making it useful for scenarios such as serialization, data binding, or custom property setters and getters.
