Generics are a new feature in version 2.0 of the C# language and the common language runtime (CLR). Generics introduce to the .NET Framework the concept of type parameters, which make it possible to design classes and methods that defer the specification of one or more types until the class or method is declared and instantiated by client code. For example, by using a generic type parameter T you can write a single class that other client code can use without incurring the cost or risk of runtime casts or boxing operations, as shown here:

C#

// Declare the generic class
public class GenericList<T>
{
    void Add(T input) { }
}
class TestGenericList
{
    private class ExampleClass { }
    static void Main()
    {
        // Declare a list of type int
        GenericList<int> list1 = new GenericList<int>();

        // Declare a list of type string
        GenericList<string> list2 = new GenericList<string>();

        // Declare a list of type ExampleClass
        GenericList<ExampleClass> list3 = new GenericList<ExampleClass>();
    }
}

• Use generic types to maximize code reuse, type safety, and performance.
• The most common use of generics is to create collection classes.
• The .NET Framework class library contains several new generic collection classes in the System.Collections.Generic namespace. These should be used whenever possible in place of classes such as ArrayList in the System.Collections namespace.
• You can create your own generic interfaces, classes, methods, events and delegates.
• Generic classes may be constrained to enable access to methods on particular data types.
• Information on the types used in a generic data type may be obtained at run-time by means of reflection.

//For Interfaces
interface IComparable <T>
//for structs
struct HashBucket <K,D>
//for methods
static void Reverse <T> (T[] arr)
//for delegates
delegate void Action <T> (T arg)

Definition: A strongly typed programming languages is one that requires the type of a variable to be explicitly stated. C is a strongly typed language. You must declare the type of data a variable will store for C to interpret it:

int myVariable;
myVariable = 25;

Perl is a loosely typed language. There is no need to declare the variable type before using it:

$myVariable = 25;
$myVariable = “A String.”;

There are two ways:

Way 1:

In aspx file:

     <td style=”width: 90px; height: 56px;” valign=”middle”>

        <asp:DropDownList ID=”ddlTime” runat=”server” Width=”131px” onchange=”clickClient();”  Height=”19px”>

</asp:DropDownList>

     </td>

In aspx.CS file:

    public static void PopulateDdlTime(DropDownList ddlTime)

    {

        ddlTime.Items.Add(new ListItem(“12:00AM–08:00AM”, “1200AM0800AM”));

        ddlTime.Items.Add(new ListItem(“08:00AM–04:00PM”, “0800AM0400PM”));

        ddlTime.SelectedValue = “0800AM0400PM”;

    }

protected void Page_Load(object sender, EventArgs e)

       {

PopulateDdlTime(ddlTime);

……

Solution:

You might have not disposed while reading/writing.
Use either of these two:

1.

StreamWriter objStreamWriterUp = null;

TextReader objTextReaderUp = null;

try

{

using (objTextReaderUp = new StreamReader(sourceFilePath)) 

{

using (objStreamWriterUp

= new StreamWriter(destiFilePath, !blIsFirstTimeCl))

{

//your code

}

}

}

catch (Exception ex)

{

throw;

}

finally

{

if (objStreamWriterUp != null)

{

                    objStreamWriterUp.Dispose();

}

       }

2.

StreamWriter objStreamWriterUp = null;

TextReader objTextReaderUp = null;

try

{

objTextReaderUp = new StreamReader(sourceFilePath);

objStreamWriterUp = new StreamWriter(destiFilePath, !blIsFirstTimeCl);

//your code

}

catch (Exception ex)

{

throw;

}

finally

{

if (objTextReaderUp != null)

{

objTextReaderUp.Dispose();

}

if (objStreamWriterUp != null)

{

objStreamWriterUp.Dispose();

}

       }

ACID (an acronymn for Atomicity Consistency Isolation Durability) is a concept that Database Professionals generally look for when evaluating databases and application architectures. For a reliable database all this four attributes should be achieved.

• Atomicity states that database modifications must follow an “all or nothing” rule. Each transaction is said to be “atomic.” If one part of the transaction fails, the entire transaction fails. It is critical that the database management system maintain the atomic nature of transactions in spite of any DBMS, operating system or hardware failure.
• Consistency states that only valid data will be written to the database. If, for some reason, a transaction is executed that violates the database’s consistency rules, the entire transaction will be rolled back and the database will be restored to a state consistent with those rules. On the other hand, if a transaction successfully executes, it will take the database from one state that is consistent with the rules to another state that is also consistent with the rules.
• Isolation requires that multiple transactions occurring at the same time not impact each other’s execution. For example, if Joe issues a transaction against a database at the same time that Mary issues a different transaction, both transactions should operate on the database in an isolated manner. The database should either perform Joe’s entire transaction before executing Mary’s or vice-versa. This prevents Joe’s transaction from reading intermediate data produced as a side effect of part of Mary’s transaction that will not eventually be committed to the database. Note that the isolation property does not ensure which transaction will execute first, merely that they will not interfere with each other.
• Durability ensures that any transaction committed to the database will not be lost. Durability is ensured through the use of database backups and transaction logs that facilitate the restoration of committed transactions in spite of any subsequent software or hardware failures.

In case of two THEN conditions of the CASE statement reference expressions of different data types. In this case, SQL Server implicitly converts the data type for the entire CASE expression to the data type in the THEN clause that has the highest order of data-type precedence.
