ConfigurationManager Class

• The ConfigurationManager class is used to read the connectionString from the configuration file.

• This class is present in the Configuration namespace.

• The assembly reference of this class is added by default for web application.

• But for windows application,we need to add assembly reference explicitly.

• To add reference in windows application project in visual studio:-

• Go to solution explorer.

• Right-Click on the references section.

• Select the Add Reference option from the menu.

• Select the System.Configuration from the dialog box and click OK.

• The assembly reference is now added for the ConfigurationManager class in windows application.

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

Adding rows to Datatable using C#.NET

Adding rows to Datatable using C#.NET Hi Readers, Today I am going to explain you 2 ways that we can use to add rows to a Data table using C#.NET. So lets begin: Add row in datatable in c# Adding rows to Datatable using C#.NET > Lets say, we have a data table with the columns ID, NAME, AGE AND SALARY and I want to add rows to this data table using C# coding . > First of all, add columns to data table using the following lines of code: DataTable dtEmployee = new DataTable("Employee"); dtEmployee.Columns.Add("ID", typeof(int)); dtEmployee.Columns.Add("NAME", typeof(String)); dtEmployee.Columns.Add("AGE", typeof(int)); dtEmployee.Columns.Add("SALARY", typeof(Decimal)); Add row in datatable in c# > Now if we want to add rows to the above data table at run time, we have the following 2 ways to do so: Adding rows to Datatable using C#.NET 1. Using DataRows :- In this, we create an o

Project available: IPMS

Following project is ready available for academic purpose and business requirements: In-Patient Management System (IPMS): Objective: This project fulfills the requirements of a clinic or hospital to manage in-patient activities i.e. patients who are admitted to the hospital.
