Can Reflection Retrieve Property Values from a Single String Input?

Using Reflection to Access Property Values from a Single String

Developers initially faced challenges using a switch statement within a GetSourceValue function to handle data transformations via reflection, particularly when dealing with diverse data types and properties. To streamline this, they aimed to retrieve property values using just a string input specifying both the class and property.

Achieving This with Reflection

This goal is achievable using reflection. The technique allows developers to provide a single string containing the class and property name, and subsequently retrieve the associated property value.

Improved Solution

A more efficient solution is presented:

<code class="language-csharp">public static object GetPropValue(object src, string propName)
{
    return src.GetType().GetProperty(propName).GetValue(src, null);
}</code>

This function takes an object (src) and a property name string (propName). It leverages reflection to access the property information from the object's type and then retrieves the property's value.

Important Considerations

While this simplifies the process, robust error handling and input validation are crucial. The code should verify the existence and accessibility of the specified property. Furthermore, performance optimization techniques should be considered for improved efficiency, especially when dealing with frequent calls to this function.
