What is the need for Flyweight Pattern in C#?

If your application includes many primitive objects, then sharing them efficiently will be a tough task. This sharing of primitive objects is achieved using Flyweight pattern in C#.

class sampleFlyweightGrouping {
private Hashtable htFlyweight = new Hashtable();
public sampleFlyweightClass() {
htFlyweight.Add("sample1", new sampleFlyweightClass());
htFlyweight.Add("sample2", new sampleFlyweightClass());
htFlyweight.Add("sample3", new sampleFlyweightClass());
}
public Flyweight fetchPrimitiveObject(string keyForObject) {
return ((sampleFlyweightClass) htFlyweight[keyForObject]);
}
}

You can have your own method definitions for sampleFlyweightClass and then create a testClass. Inside Main method of testClass, create an instance of sampleFlyWeightGrouping. With this instance, you can call fetchPrimitiveObject for each of the primitive objects appended and then call appropriate methods of this object.
