pass parameter to C# method with [Square brackets]

Question

how to pass parameter between [Name]
please see

 public static string GetNationalCode(string Name)
 {
            foreach(var User in Users)
            {
                if(User.Name== Name)
                {
                    return User.Code;
                }
            }
            return "";
  }

I want to convert the top method to this code

  public static string GetNationalCode[string Name]()
  {
            foreach(var User in Users)
            {
                if(User.Name== Name)
                {
                    return User.Code;
                }
            }
            return "";
 }

What is the value in making this change? What goal are you trying to achieve? — , Oct 18 '19 at 20:01
GetNationalCode(List nameList) i assume, and then foreach(var name in nameList) { ... } ? At Least i think that is your question but i am not sure. (your locals should not start with capitals by the way) | and where do you get Users from is that a this.Users ? — edelwater, Oct 18 '19 at 20:01
Perhaps you should take a look at this : https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/indexers/using-indexers — Jonas W, Oct 18 '19 at 20:02
What you're describing, an indexed *non-default* property, is possible in VB.NET but not in C#. In C#, it's emulated by returning an object that has an indexer (indexed *default* property), as germi's answer says. You could write it in VB.NET, although it doesn't use square brackets, and then in C#, you'd be calling `get_GetNationalCode(name)` (although you'd probably remove `Get` so it ends up being `get_NationalCode(name)`). — madreflection, Oct 18 '19 at 20:32

I believe what you are looking for are Indexers.

As @Rotem points out in the comments though, indexers are not possible as static methods (as discussed here for example).

What led you to that conclusion and how do indexers tie into a static method? – Rotem Oct 18 '19 at 20:12

@Rotem I'm guessing OP is misunderstanding what square brackets are generally used for, so this would probably be the place to start. – Dortimer Oct 18 '19 at 20:14
@Rotem They don't. It just seemed to me that that's what the OP was looking for. That they are not possible as static is a good point that I should mention in the answer, though. – germi Oct 18 '19 at 20:14
