How Can I Retrieve the Name of a Struct Field Using Go Reflection?

Retrieving Name of Struct Field with Reflection

When using the reflection package in Go, it's possible to manipulate structures and fields dynamically. However, an issue arises when attempting to print the name of a specific field using reflection.

Consider the following code snippet:

In this example, the goal is to print "Foo", but it prints "string" instead. This is because the Field(0) method returns a reflect.StructField value, which contains information about the field's type, not its name.

To retrieve the name of the field, you need to use the Type() and Field() methods on the reflect.Type value:

The Field(0) method on the reflect.Type value returns a reflect.StructField that represents the first field of the struct. The Name field of this reflect.StructField contains the name of the field.
