How to use constants in .NET?


I have a written this Dev tip for the new folk who entered in this Dev World.

Normally in the development we use some of the success message's or failure messages in general common message's.We do have a habit of writing the messages as given below

MessageBox.Show("Successfully created a record!");

 MessageBox.Show("Successfully deleted a record!");

We can make use of Constants in .NET which will be declared using the keyword "const".For the above scenario we can create a  class like "Messages.cs" and define constants as given below


 public class Messages

    {

        public const string strUserExist = "User Name already exists.";

        public const string strUserSaved = "User information saved successfully.";

        public const string strUserDeleted = "User deleted successfully.";

    

    }
Advantage :We can change the message text only in the Message.cs class which will be applicable through out the project where ever we have used this constant.

 Usage :

 MessageBox.Show(Message.strUserExist);

 The above scenario is one of the example I have explained.Guys! There are  many scenario's where we use like this according to the purpose.

We can do this either in Windows or Web Development also.

  I hope this will give a basic idea about constants in .NET to the newbies.

 Happy Coding :-)

Exporting to excel from a custom class object using C#.NET

We may face a scenario to export the data of custom class object to excel using InterOp .You can get the property name's from the class object using Reflection.Create a work sheet header by reading the each propety of the class object.I have created a separate method to get the all properties into a list collection of string as given below         ///         /// Get the list of Properties Name into a list collection.         ///         ///         ///         public List GetPropeties(Employee objEmployee)         {             Type myType = objEmployee.GetType();             IList props = new List (myType.GetProperties());             List lstPropertiesNames = new List ();             foreach (PropertyInfo prop in props)             {                 lstPropertiesNames.Add(prop.Name);             }             return lstPropertiesNames;         } We need to call this method to create the worksheet header's as given beloe                 List lstProperties = GetPropet

Why Dispose() is preferred than Finalize() for Un-Managed Resources in .NET?

Image
Memory management is very important in any application development.The Garbage collector of .NET does almost all clean up activity for your objects.For unmanaged resources (Ex:Windows API created objects, File, Database connection objects, COM objects, etc.) are outside the scope of .NET framework. Why Dispose() is preferred than Finalize() If we use the " Finalize() " method,the  Garbage collector has to make two round in order to remove the objects. For an instance ,let me explain clearly if we have two objects as Object1 and Object2 and we finalize the Object2 as given in the below image.The GC has to categorize the two objects and put the Finalize objects into Finalization Queue.The GC will clean the object1 which doesn't use the Finalize() method and process the second round of cleaning the Finalization Queue. Now at this the " Dispose() " method will come into picture.This method belongs to IDisposable() interface .So the best practise to rele
