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 do it with some preparation using delegates, like this:

private static readonly IDictionary> actionByType =
    new Dictionary> {
        {"ReadFile", ReadFile}
    ,   {"ReadMSOfficeWordFile", ReadMSOfficeWordFile}
    ,   {"ReadMSOfficeExcelFile", ReadMSOfficeExcelFile}
    ,   {"ReadPDFFile", ReadPDFFile}
    };

When it is time to call your action, do it as follows:

actionByType[actionName](file);
