Can Reflection Dynamically Retrieve Property Values Using Only a String Parameter?

Use the reflex dynamic to obtain the attribute value

In order to simplify the data conversion task, developers want to find a method that can use string parameters to directly obtain the attribute value through reflection, thereby avoiding the needs of the explicit type comparison and the standard attribute name.

Question:

Is it possible to use a string parameter containing a class name and attribute name to obtain the attribute value?

Answer: Yes, using reflex can be dynamically implemented. The following code fragment demonstrates how to achieve:

In this method, the attribute value is obtained by obtaining the attribute name provided by the reflection, and then accessing its value. Please note that for actual use, verification and error treatment may be needed.

How to use:

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

To use this method, you only need to pass the target object and the required attribute name (as a string) as a parameter. For example, if you have an object called

, it has a attribute called , you can retrieve its value in the following way:

This method provides a convenient and flexible way to dynamically access the attribute value, without the need to explicitly check or predetermine attribute names. person
