Can C# Reflection Change Private Property Values from a String?

Can Reflection Alter Property Values from String Input?

Utilizing reflection in C#, you can access private members of a class, including its properties. This enables you to manipulate the underlying values of these properties, despite their access restrictions.

Example: Setting Property Values Reflectively

Consider the following code:

string propertyName = "first_name";
// Assume there's a property named first_name in the class

To set the value of this property using reflection, follow these steps:

1. Obtain the property info using Reflection:

   Type propertyType = typeof(TargetClass);
   PropertyInfo propertyInfo = propertyType.GetProperty(propertyName, BindingFlags.NonPublic | BindingFlags.Instance);

2. Utilize the SetValue method to alter the property value:

   object targetObject = new TargetClass();
   propertyInfo.SetValue(targetObject, "New Value", null);

Note: In the example above, TargetClass represents the class containing the first_name property. To access private or protected properties, adjust the BindingFlags in GetProperty() accordingly.
