How Can Reflection Be Used to Retrieve Attribute Names and Values from Properties?

Use the reflex to obtain the attribute name and value

In software development, reflex allows programmers to check and operate metadata related to the type and members during runtime. In this case, we are facing the challenge of the attribute name and value associated with attributes with reflection.

For this reason, we first use the

method to retrieve the

instance array of typeof(Book).GetProperties() class attributes. Subsequently, for each object, we use the Book method to determine whether there is any PropertyInfo type attribute. PropertyInfo GetCustomAttributes() If attributes are found, we can retrieve the name of the attribute from the Author object and retrieve the value of the attribute in the attribute instance. By iterating all attributes and attributes in this way, we can build a dictionary to store and return key values ​​pairs of attribute names and values.

For example, the following C# code demonstrates how to complete this task: AuthorAttribute PropertyInfo

By using the reflection function, this method allows us to effectively retrieve the attribute names and values ​​of attribute associated with attributes in a dynamic and customized manner.
