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

I believe what you're looking for will need some refactoring of your code.

All of your "cases" (TextFile, MSOfficeWordFile, MSOfficeExcelFile, PdfFile) should be their own classes which implement a single interface.

Your interface should be named something like "IReadableFile" and specify a method named "ReadFile()".

Each class should have their own implementation of "ReadFile()"

Example:

public interface IReadableFile
{
    void ReadFile();
}

---

public class MSOfficeWordFile : IReadableFile
{
    public void ReadFile()
    {
        ReadMSOfficeWordFile(file);
    }
} 

---

foreach(IReadableFile file in files)
    file.ReadFile();

Code may contain some mistakes, but I hope you get the idea.
