CSharp transactions

CSharp transactions play a vital role in ADO.Net development. Transaction , in simple words, can be defined as the action that needs to be performed in the form of assets movements in or movements out.
Since money is also a part of an asset due to its value for both parties i.e sender and receiver.
The movements about sending and receiving are called Transactions
The transactions, which are used in CSharp, allows us to operate on number of SQL statements and we may
abort transaction whenever there is an error in one of the sql statements. Lets see it in an example:

This is our web.config file

    <?xml version=”1.0″?>
    <add name=”MyConnection” connectionString=”Data Source=ABC;Initial Catalog=XYZ;Integrated Security=True”/>

// this is our code file
using System;
using System.Data.SqlClient;
using System.Diagnostics;
namespace ADOTransaction

public class TransactionClass
public void TransactionTest()
SqlConnection con = new SqlConnection(“ConfigurationManager.ConnectionStrings[“MyConnection”].ConnectionString;”);
SqlCommand cmd = connection.CreateCommand();
cmd.CommandText =”INSERT INTO MyTable(ID, Name) VALUES(@ID, @Name)”;
SqlTransaction MyTransaction = connection.BeginTransaction();
cmd.Transaction = MyTransaction;
cmd.Parameters.AddWithValue(“@ID”,1234 );
cmd.Parameters.AddWithValue(“@Name”, “Adeel”);
// If the command executes perfectly, then the transaction succeeds
catch (Exception ex) // catch the error
Trace.WriteLine(ex.Message); // write error on trace
MyTransaction.Rollback(); // Abort all the actions performed in the above executed transactions
// don’t forget to close the connection
