Question

I need to write a simple class.
I need 2 methods:

Vector property = new Vector();
property.add("key", "value"); //set value of key
property.get("key"); //return value of key

Does CSharp have a class like that?

I’m trying write my own class

string[] keys;

public void add(string key, string value)
{
 this.keys[key] = value;
}

but string can not be index of array(but must).

Any ideas?
Thanks.

You may use Dictionary<TKey,TValue> to do this. You may also define Vector as a class of Dictionary if you would like to use Vector as a Dictionary

Example

class Vector : Dictionary<string,string>
{
    public string Get(string Key) //Create a new void Get(string Key) which returns a particular value from a specific Key in the Dictionary (Vector)
    {
        return this[Key]; //Return the key from the Dictionary
    }
    public void add(string Key, string Value) //Create a new void Add(string Key, string Value) which creates a particular value referring to a specific Key in the Dictionary (Vector)
    {
        this.Add(Key, Value); //Add the key and its value to Vector
    }
}

Vector property = new Vector(); //Initialize a new class Vector of name property
property.add("key", "value"); //Sets a key of name "key" and its value "value" of type stirng
MessageBox.Show(property.Get("key")); //Returns "value"
//MessageBox.Show(property["key"]); //Returns "value"

This will create a new class Vector which implements Dictionary so that you’ll be able to use Vector as a Dictionary.

Notice: The Dictionary<TKey, TValue> is a generic class providing a mapping from a set of keys to a set of values. Each addition to the dictionary consists of a value and its associated key. Retrieving a value by using its key is very fast because the Dictionary<TKey, TValue> class is implemented as a hash table.
