Expando Object

The ExpandoObject class enables you to add and delete members of its instances at run time and also to set and get values of these members.

Creating a dynamic instance:

       dynamic Student = new ExpandoObject();
       Student.ID = 1;
       Student.Name = "John";

Student.Grade = 10;


Creating a nested dynamic instance:

       Student.Addess = new ExpandoObject();
       Student.Addess.City = "London";
       Student.Addess.Country = "UK";
       Student.Addess.StreetNo = 123456;

Dynamically binding an Event

Student.Click += new EventHandler(SampleHandler);
 
private void SampleHandler(object sender, EventArgs e)
{
//throw new NotImplementedException();
}

Pass parameter as dynamic.

public void Write(dynamic Student)
{
//do stuff
}

Dynamicly add xsi:schemaLocation="location" to XML

// Comment
//create XML

XmlDocument doc = new XmlDocument();



//header

XmlDeclaration decl = doc.CreateXmlDeclaration("1.0", "UTF-8", null);

doc.AppendChild(decl);



//

doc.Schemas.Add("test:schema:v1", "http://sample.com/schema.xsd");

XmlElement decElem = doc.CreateElement("root");

XmlAttribute attr = doc.CreateAttribute("xsi", "schemaLocation", "http://www.w3.org/2001/XMLSchema-instance");

attr.Value = "test:schema:v1 schema.xsd";

decElem .Attributes.Append(attr);

decElem .SetAttribute("xmlns", "decElem");

doc.AppendChild(docElem);

Can't connect to TFS 2010

I've tried:

1. Stop Collection / Start Collection
2. Detach / Attach Collection
3. IIS Stop, Strat , Reset
4. Flush DNS
5. Reinstalled TFS

and nothing worked.

I've checked the port 8080 in windows firewall, and was allowed through the firewall but the rule was set to PUBLIC and the network is PRIVATE. Added "private" to the rule and everything works again.
