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

You can use a delegate:

Action action;
switch (filetype.Value) {
  case "ReadFile":
    action = ReadFile;
    break;
  case "ReadMSOfficeWordFile":
    action = ReadMSOfficeWordFile;
    break;
  case "ReadMSOfficeExcelFile":
    action = ReadMSOfficeExcelFile;
    break;
  case "ReadPDFFile":
    action = ReadPDFFile;
    break;
  default: 
    throw new NotImplementedException("Unhandled file type '"+filetype.Value+"'.");
}
foreach (string file in files) {
  action(file);
}
