Retrieving Keys of a Particular Group

To return list of keys that belongs to a specified group and sub-group, you can use the GetGroupKeys method. This method returns a list of keys.

string groupName = "Product";
string subGroupName = "Beverages";

try
{
    ArrayList keys = cache.GetGroupKeys(groupName, subGroupName);

    foreach (object obj in keys){
        //do something
    }
}
catch (Exception ex)
{
    //handle exception
}

Retrieving Keys and Values of a Particular Group

To return the dictionary of keys and values that belong to a specified group and sub-group, the GetGroupData method can be used. This method returns a dictionary of keys and values.

string groupName = "Product";
string subGroupName = "Beverages";

try
{
    ArrayList keys = cache.GetGroupKeys(groupName, subGroupName) as IDictionary;

    if (data.Count > 0)
    {
        IDictionaryEnumerator result = data.GetEnumerator();

        while (result.MoveNext())
        {
            string key = (string)result.Key;
            Product val = (Product)result.Value;
            //do something
        }
    }
}
catch (Exception ex)
