How to enumerate Generic Dictionary .NET list

At first i found that enumerating a .net Dictionary class seem to be difficult but later i found that there is a way of doing this for example:

//instantiate a dictionary list
Dictionary _PointDic = new
Dictionary();
public Dictionary
PointDic
{
get { return _PointDic; }
set { _PointDic = value; }
}
//add value to named key
public void AddPoints(int point, string
ruleName)
{
int temp = 0;
if (!_PointDic.TryGetValue(ruleName, out
temp))
{
_PointDic.Add(ruleName,
point);
}
else
{
_PointDic.Remove(ruleName);
_PointDic.Add(ruleName,
point);
}
}
//sum up the values in the dictionary list
public int
CalculatePoints()
{
int totalpoints = 0;
foreach
(KeyValuePair s in _PointDic)
{
totalpoints +=
(int)s.Value;
}
return totalpoints;
}

ConfigurationManager .Net

How you read your custom setting in your application configuration file.

//Read settings
public static string ReadConfig(string key)
{
return ConfigurationManager.AppSettings.GetValues(key)[0];
}

//Update Settings & get immediate changes
public static void SetConfig(string key, string value)
{
Configuration con = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
con.AppSettings.Settings[key].Value = value;
con.Save(ConfigurationSaveMode.Full);
ConfigurationManager.RefreshSection("appSettings");
}

Create a distributable workflow enabled smart client

We want to develop a windows application with workflow enabled. The easiest and fastest way is to use Microsoft Workflow Foundation which give you a complete API for designing any workflow application that you can think of.

We wanted to develop a windows application which has to be distributed to multiple computers and having multiple users. Here we have one challenge, we need to host the Workflow. The most simple implementation is to host workflow in a dedicated server where many clients can access to it. Next we have to expose the workflow as webservice, this is important because workflow as webservice can give you the maximum flexibility in connectivity and interoperability. For example, connect a mobile device that runs java application. Sound interesting?

I will post the tutorial on building your first smart client workflow enabled application here for your reference.
