I'm trying to use the Convert method on functions as well as actions, so I can avoid writing duplicate methods taking in delegates of Func type. Convert method comes from Convert Action<T> to Action<object>
public class Program
{
static void Main(string[] args)
{
var program = new Program();
var mi = program.GetType().GetMethod("Function", BindingFlags.Instance | BindingFlags.Public);
// Can be any version of Func
var funcType = typeof(Func<int, int>);
// Create action delegate somehow instead
var del = mi.CreateDelegate(funcType, null);
// Or dynamically convert the Func to a corresponding Action type (in this case Action<int>)
}
// Or find a way to pass it in as a parameter here
public Action<object> Convert<T>(Action<T> action)
{
return o => action((T)o);
}
public int Function(int five)
{
return five;
}
}
I think you are looking for something like this:
But for all variants of
Func<T1,T2....>
I think this would work:
With usage:
You'll not be able to get it to infer the parameters and return type without copy and pasting the first example for all variants of
Action<T1...>
andFunc<T1,T2...>
.
