Question

I have a few procedures, for simplicity sake, look like the following:

public string FetchValueAsString(string key) public int FetchValueAsInteger(string key) public bool FetchValueAsBoolean(string key) public DateTime FetchValueAsDateTime(string key) 

I know I could just have one method that returns and object type and just do a conversion, but I’m wondering if there is a way I can just have one method called, and somehow use generics to determine the return value … possible?

Answer 1

public static T FetchValue<T>(string key) {     string value;       // logic to set value here       // ...       return (T)Convert.ChangeType(value, typeof(T), CultureInfo.InvariantCulture);   }
