Invoking Structs and their Methods by Name in Go
When working with structs, there may be instances where you need to invoke a specific method dynamically by its name. This can be useful in situations where the method name is determined at runtime or when you want to generalize code for working with different structs.
Unlike some other languages, Go does not provide a straightforward mechanism for calling methods by their names. However, by utilizing the power of reflection, it is possible to achieve this functionality. Here's how:
For example, considering the following struct and method:
type MyStruct struct { // Fields here } func (p *MyStruct) MyMethod() { fmt.Println("My statement.") }
You can call this method dynamically as follows:
structValue := reflect.ValueOf(&myStruct) method := structValue.MethodByName("MyMethod") method.Call([]reflect.Value{})
This code will print "My statement." to the console.
Note: It's important to ensure that both the struct and method you're trying to call are visible and accessible within the current package or scope.
