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 could keep a Dictionary of delegates, as the simplest way:

Dictionary> fileReaders = new Dictionary>() {
    {"ReadFile", ReadFile},
    {"ReadOfficeWordFile", ReadOfficeWordFile},
    {"ReadOfficeExcelFile", ReadOfficeExcelFile},
    {"ReadPDFFile", ReadPDFFile}
};

Then call it like this:

fileReaders[fileType.Value](file);

Depending on what your methods return, you may have to change the type of the delegate (Action means void something(string someparam) as a method signature, for example) as well.
