Use variable in place of function name

Question

I\'m using the following right now:

foreach (string file in files) {
    switch (filetype.Value) {
        case \"ReadFile\":
            ReadFile(file);
                


        

Answer 1

If you're looking for a way to avoid the explicit mapping of method names to string values you could use reflection to do dynamic method invocation (this assumes filetype.Value is of type String)

String method_name = String.Empty;
foreach (string file in files) {
    method_name = filetype.Value;
    System.Reflection.MethodInfo method = this.GetType().GetMethod(method_name);
    method.Invoke(this, new object[]{file});
}
