What base class do custom Field Controls inherit from?

What are the two base classes a WebPart you are going to use within SharePoint 2007 can inherit from?

  
There are two base classes that a WebPart which is going to be consumed by SharePoint can inherit from, either the
SharePoint WebPart Base class
or the
ASP.NET 2.0 WebPart base class.
When inheriting from the SharePoint WebPart Base class your derived WebPart class will inherit from Microsoft.SharePoint.WebPartPages.WebPart. When inheriting from the ASP.NET 2.0 WebPart base class your derived WebPart class will inherit from System.Web.UI.WebControls.WebParts.WebPart. It is considered good practice to use the ASP.NET WebPart base class since the old base class is meant for backwards compatibility with previous version of SharePoint, however there are four exception when it is better to leverage functionality from the SharePoint WebPart base class:
Cross page connections
Connections between Web Parts that are outside of a Web Part zone
Client-side connections (Web Part Page Services Component)
Data caching infrastructure
(More...)

What base class do event receivers inherit from?

  
Event receivers either inherit from the SPListEventReciever base class or the SPItemEventReciever base class, both which derive from the abstract base class SPEventReceiverBase.

Can we call a base class method without creating instance?

  
Its possible If its a static method.

Its possible by inheriting from that class also.

Its possible from derived classes using base keyword. (More...)

What is an orthogonal base class?

  
If two base classes have no overlapping methods or data they are said to be independent of, or orthogonal to each other. Orthogonal in the sense means that two classes operate in different dimensions and do not interfere with each other in any way. The same derived class may inherit such classes with no difficulty. (More...)

If any .NET language has access to everything in the Base Class Library, why is there so much talk about C#?

  
Although in theory all .NET languages have equal access to the BCL, in reality it was left up to the language teams to determine what level of support they wanted to offer, at least beyond the minimums needed for basic compliance. In our opinion, C#, because it was developed as a new language specifically for the .NET platform, has the best support for .NET applications. (More...)

How do you inherit from a class in C#?

  
Place a colon and then the name of the base class. Notice that it's double colon in C++. (More...)
