I am a newbie to programming c# and I want to add an element to an array.
Here's my function:
public bool AddPlayer(string PlayerName,string token)
{
static int i = 0; // <---- Error
if ( PlayerIndex < MAX_NUMBER_OF_PLAYERS )
{
Player[i]= PlayerName
i++;
}
return true;
}
The static int i = 0 results in an error. Is there another way to do this?
It sounds like you don't really know how many players you are going to store (up to a maximum). In this case you should rather use a List<string> to store your player names, which will resize to fit any number of players:
private List<string> players = new List<string>();
public void AddPlayer(string playerName,string token)
{
players.Add(playerName);
}
if you use List instead of an array.... (its far more likely a List will serve you better)
you can go Player.Add(PlayerName);
eg
var players = new List<string>();
players.Add("bob");
players.Add("mary);
but most likely you will want a player class, so you can add other interesting bits of information about "players".
class Player
{
public string Name { get; set; }
}
then
var players = new List<Player>();
players.Add(new Player() { Name = "bob" });
players.Add(new Player() { Name = "mary" });
The usual way to do this is to use a List, not an array. However, assuming you can't do that, you should make the index a (non-static) member of the class and initialise it to 0 in the constructor.
You'll need to make i a static class member, not a local variable in the method. You probably want to give it a more meaningful name, too.
If you actually need a static variable then you need to define it outside of the method and within the class definition.
static int i = 0;
public bool AddPlayer(string playerName, string token)
{
// method implementation here...
}
you can change "i" as Static class member, or you can change the function to a static method
public static bool AddPlayer(string PlayerName,string token)
