What are the different ways a method can be overloaded?

Different parameter data types, different number of parameters, different order of parameters can be used to overload a method

What is serialization in .NET? What are the ways to control serialization?

  
Serialization is the process of converting an object into a stream of bytes. Deserialization is the opposite process of creating an object from a stream of bytes. Serialization/Deserialization is mostly used to transport objects (e.g. during remoting), or to persist objects (e.g. to a file or database).Serialization can be defined as the process of storing the state of an object to a storage medium. During this process, the public and private fields of the object and the name of the class, including the assembly containing the class, are converted to a stream of bytes, which is then written to a data stream. When the object is subsequently deserialized, an exact clone of the original object is created.
Binary serialization preserves type fidelity, which is useful for preserving the state of an object between different invocations of an application. For example, you can share an object between different applications by serializing it to the clipboard. You can serialize an object to a stream, disk, memory, over the network, and so forth. Remoting uses serialization to pass objects "by value" from one computer or application domain to another.
XML serialization serializes only public properties and fields and does not preserve type fidelity. This is useful when you want to provide or consume data without restricting the application that uses the data. Because XML is an open standard, it is an attractive choice for sharing data across the Web. SOAP is an open standard, which makes it an attractive choice.

There are two separate mechanisms provided by the .NET class library -
XmlSerializer and SoapFormatter/BinaryFormatter. Microsoft uses XmlSerializer for Web Services, and uses

SoapFormatter/BinaryFormatter for remoting. Both are available for use in your own code. (More...)

What is Method overloading?

  
Method overloading occurs when a class contains two methods with the same name, but different signatures. (More...)

What is Method Overriding? How to override a function in C#?

  
Use the override modifier to modify a method, a property, an indexer, or an event. An override method provides a new implementation of a member inherited from a base class. The method overridden by an override declaration is known as the overridden base method. The overridden base method must have the same signature as the override method.
You cannot override a non-virtual or static method. The overridden base method must be virtual, abstract, or override. (More...)

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 Method used to bind the data into gridview ?

  
DataBind() Method used to bind the data into gridview (More...)

What method is used to place a value onto the top of a stack?

  
push() method, Push is the direction that data is being added to the stack. push() member method places a value onto the top of a stack. (More...)

What method removes the value from the top of a stack?

  
The pop() member method removes the value from the top of a stack, which is then returned by the pop() member method to the statement that calls the pop() member method. (More...)

Describe ways of cleaning up objects.

  
The run time will maintain a service called as garbage collector.
this service will take care of deallocating memory corresponding to
objects.it works as a thread with least priority.when application
demenads for memory the runtime will take care of setting the high
priority for the garbage collector,so that it will be called for execution
and memory will be released.the programmer can make a call
to garbage colector by using GC class in system name space. (More...)

How can you reference current thread of the method ?

  
"Thread.CurrentThread" refers to the current thread running in the method."CurrentThread" is a public static property. (More...)

How do I call a member method and pass a primitive type (Value Type) by reference?

  
Use the ref keyword when declaring the parameter of the method, for example:

public bool GetValue( ref int returnValue );

This will pass the numeric by reference.You can modify the value of returnValue within the body of GetValue and it will persist when the method call returns. (More...)

How can I look up a parent class method or property of any System-level object?

  
Use the Class View window, accessed from the standard toolbar by clicking View | Class View. (More...)

What are the ways available in SQL Server to execute SQL statements?

  

SQL Server uses different ways to execute SQL statements which are listed below.

1)Single SQL statement processing
2)Batch processing
3)Stored procedure and trigger execution
4)Execution plan caching and reuse
5)Parallel query processing

(More...)

How do you invoke a web method of web service in AJAX?

  
In order to use a webmethod of a webservice, we need to add the reference of webservice in the section of ScriptManager. Under services you have to configure the servicepath.

< asp:ScriptManager ID="ScriptManager1" runat="server">
< Services>
< asp:ServiceReference Path="..\service1.asmx" />
< /Services>
< /asp:ScriptManager>

Inside JAvascript Use methods of this service directly like
service1.methodname() (More...)
