How Can I Dynamically Retrieve Property Values in .NET Using Reflection?

Retrieving Property Values Dynamically using Property Name

Accessing property values programmatically can be useful in various scenarios, such as dynamic object manipulation or data serialization. In .NET, you can achieve this using reflection.

To retrieve the value of a property based on its name, you can utilize the GetProperty method of the Type class. It takes the property name as a parameter and returns a PropertyInfo object. This object represents the specified property and allows you to manipulate its behavior and data.

To obtain the property value, you can call the GetValue method of the PropertyInfo object. This method takes the object to retrieve the value from and an array of optional index values (which is typically null for non-indexed properties).

Here's an example that demonstrates how to write a method that retrieves property values by name:

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

In the given example class, you can call this method as follows:

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

This will assign the value of the Make property (Ford) to the make variable. Note that the property value is returned as an object and may need to be cast to the appropriate type.
