I have a table contains the columns Title and Info.
I would like to create an array it's index will be the Title, and actual value of the array in that index is the Info in the same row.
So if I have 3 Rows like that:
Title Info
ABC Hi
DEF Sup
GHI Hello
I would like to ask for StringArray["ABC"], and this will return "Hi".
How can I do that?
Thanks Guy
You want a Dictionary<String, String>, not a string array.
var myStrings = new Dictionary<String, String>();
myStrings.Add("ABC", "Hi");
myStrings.Add("DEF", "Sup");
myStrings.Add("GHI", "Hello");
Console.WriteLine(myStrings["ABC"]);
Arrays can only be indexed with an integer. You would have to use Dictionary<string, string>, or some other type that implements IDictionary<string, string>, or you could implement your own type with a string indexer.
Please refer to Dictionary for that
You can do in this way
Dictionary<string, string> Book = new Dictionary<string, string>();
Book.Add("ABC","Hi");
Book.Add("DEF","Sup");
Book.Add("GHI","Hello");
so on and so forth.
So then when you say
Book["ABC"] it will return Hi
You should use dictionary to implement it.
var table = new Dictionary<string,string>(
{"ABC", "Hi"},
{"DEF", "Sup"},
{"GHI", "Hello"}
);
now you can use it
var info = table["ABC"];
you should be careful an exception will be thrown if you use unexisted key
you can use TryGetValue to avoid this exception
string info;
if(!table.TryGetValue("ABC", out info))
{
info = "default value if required";
}
