[英]index out of range exception array
I don't understand why I am getting an out of range error. 我不明白为什么会出现超出范围的错误。 Is my code set up improperly to have the array increase in size with each word entered?
我的代码设置是否不正确,以使输入的每个单词的数组大小都会增加? Note: I have some classes not shown here.
注意:我有些班级未在此处显示。 Please tell me what I have to do in order to make the array increase by one every time a new word is entered.
请告诉我我必须做些什么,以便每次输入一个新单词时使数组增加一。
class Program
{
static String[] Parse(String commandLine)
{
string[] stringSeparators = new string[] { "" };
String[] localList = new String[commandLine.Count((char f) => f == ' ') + 1];
localList = commandLine.Split(stringSeparators, StringSplitOptions.None);
return localList;
}
static void Main(string[] args)
{
Verb cVerb = new Verb(); //constructors begin here
Noun cNoun = new Noun();
Item itemName = new Item();
Player myPlayer = new Player();
String commandLine;
Room northRoom = new Room();
Room southRoom = new Room();
northRoom.setRoomDesccription("You stand in the center of the northern room. It smells musty");
southRoom.setRoomDesccription("You stand in the center of the southern room. It is made of crumbling stone");
myPlayer.setRoom(northRoom);
Console.WriteLine("Welcome young hero, to the world of Argandia");
while (cVerb.getName() != "Exit") // continue playing as long as verb entered =/ "exit"
{
//Room Description
myPlayer.getRoom().printDesc();
//Player Input
Console.WriteLine("You can now type a verb then a noun");
commandLine = Console.ReadLine();
int numWords = commandLine.Count((char f) => f == ' ') + 1;
String[] verbNounList = new String[numWords];
verbNounList = Parse(commandLine);
//process input
if (numWords > 0)
{
cVerb.setName(verbNounList[0]);
if (cVerb.getName() == "Exit")
{
Console.WriteLine("Thanks for playing\nSee you next time\nPress any key to exit...");
Console.ReadKey();
Environment.Exit(0);
}
if (numWords > 1)
{
cNoun.setName(verbNounList[1]);
}
if (numWords == 2)
{
}
else
{
Console.WriteLine("We are only able to support 2 words at this time, sorry\nPress any key to continue...");
}
}
}
}
}
Perhaps you should use a collection like List<string>
. 也许您应该使用
List<string>
类的集合。 A dynamic alternative to an array: 动态替代数组:
public static IEnumerable<string> Parse(string commandLine)
{
foreach (var word in commandLine.Split(' '))
yield return word;
}
static void Main(string[] args)
{
string testCommandLine = "Hello World";
var passedArgs = Parse(testCommandLine);
foreach (var word in passedArgs)
{
//do some work
Console.WriteLine(word);
}
Console.Read();
}
