Description

Determines whether the Hashtable contains a specific key.

This method implements IDictionary.Contains. It behaves exactly like ContainsKey. This method is an O(1) operation.

// Searchs for a value on the hash table

var h : Hashtable;
h = new Hashtable();
h.Add(1,"one");
h.Add(2,"two");
h.Add(3,"two");
if(h.Contains(1)) {
	Debug.Log("Key '1', has been found!");
}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Hashtable h;
    void Example() {
        h = new Hashtable();
        h.Add(1, "one");
        h.Add(2, "two");
        h.Add(3, "two");
        if (h.Contains(1))
            Debug.Log("Key '1', has been found!");
        
    }
}
