.config files

By

> To store the connection strings at a place, configuration files are used in .net application. 
> We use web.config file for web application and app.config file for windows application.

WEB.CONFIG:-

•         It’s a configuration file for web application.
•         This file is used to store the connection string which contains the code for the connectivity with the data source.
•         This file is added by default if we are developing ASP.NET web application.
•         The extension of a configuration file is .config.
•         A configuration file can store multiple connectionStrings.


       APP.CONFIG:-

•         It’s a configuration file for windows application.
•         This file is also used to store the connection strings which contains the code for the connectivity with the data source.
•         This file has to be added explicitly as it is not added by default.
•         The extension of this configuration file is .config.
•         A configuration file can store multiple connectionStrings.
•         To add it in the application:

                 > Open project in visual studio.

            > Go to solution explorer.

            > Right click on the project name.

            > Click on the new item option.



            > Select the application configuration file from the dialog box.


            > Specify name of file(by default it is app.config).

            > Click add button.

            > File is now added to the project.


That's it....Thanks for reading this post...

datatable compute sum in c# | datatable compute() function Hi Readers, Today I am going to explain you the use of compute() function of Data table using C#.NET .  Let's begin.. datatable column sum in c# datatable compute sum in c# | datatable compute() function Let's say that we have the following rows filled in the Data table with the columns ID,NAME,AGE and SALARY as shown in snapshot below:- employees detail in datatable In order to calculate the figures like total of salary, average of salary, maximum salary and minimum salary, we can use the compute() function of the Data table. The compute() function loops through each value of the column's cell and then perform the calculation. For the above data table's salary column, lets find the total, average, maximum and minimum of salary one by one using compute() function:- datatable compute sum in c# | datatable compute() function Calculate the total of sala
