what is the meaning of (Guid) in c#

i saw this while making windows form application while using c# ,working on data set .

A little more context would be helpful. I'm guessing that you've found it infront of an expression, in which case it is converting the value of the expression into a value of type Guid

DataSet carinventoryDS= new DataSet("Car Inventory");
carinventoryDS.ExtendedProperties["TimeStamp"] = DateTime.Now;
carinventoryDS.ExtendedProperties["DataSetID"]=Guid.NewGuid();

Guid.NewGuid() is calling the static NewGuid() method on the Guid class. 'Guid' is the type name. If you've not changed your IDE colours, it'll show up in a sort of duck-egg blue to indicate it is a type. What this method returns is a Guid instance (i.e. an object of type Guid, not the type itself) that has been poplated with a unique value via one of the GUID generation algorithms.
