We hope the above C# programming tutorial has illustrated how to access a PostgreSQL Azure database using C# and the Microsoft.NET framework. NET Conclusion to PsotgreSQL and C# Database Connection Show(ex.Message, "Error Occured", MessageBoxButtons.OK, MessageBoxIcon.Error) NpgsqlDataAdapter objDataAdapter = new NpgsqlDataAdapter(strpostgracecommand, objpostgraceConn) String strpostgracecommand = "select employeeid, employeename, employeesalary from employee" NpgsqlConnection objpostgraceConn = new NpgsqlConnection(strConnString) String strConnString = "Server=remote_server Port=5432 User Id=user Password=mypassword Database=test" Npgsql Data Provider for PostgreSQL Installedįinally, implement the following C# PostgreSQL connection code, written using the NpgsqlConnection in the Program.cs file of the console application, which will connect the Azure PostgreSQL database and import data from the employee table: static void PostgreSQLConnection() Install the Npqsql data provider as indicated below: Then, search for PostgreSQL and choose Npgsql. The next step is to right-click on the project and select Manage NuGet Packages. New Console Project in VS Solution Explorer It should look similar to how ours looks in the Solution Explorer below: Click Create and a new console application will be created:Ĭonsole Project Name and Framework VersionĪ new project will be created. Next, add the new Project Name and choose the Framework version. Select a Console App project, as depicted below: Open Visual Studio 2019 and Create a new project: INSERT INTO employee (employeeid, employeename, employeesalary) VALUES (4, 'Pintu', 1920.99) INSERT INTO employee (employeeid, employeename, employeesalary) VALUES (3, 'Biltu', 1900.99) INSERT INTO employee (employeeid, employeename, employeesalary) VALUES (2, 'Laltu', 2400.55) INSERT INTO employee (employeeid, employeename, employeesalary ) VALUES (1, 'Tapas', 3400.99) Connect the Azure PostgreSQL server from the Visual Studio SQL Server Object explorer and create the following employee database and table, using the C# code example here: CREATE TABLE employee Note the connection string in the code below, once the server instance is created.

How to Create a Postgres Database in Azure Cloudįor the purpose of demonstrating PostgreSQL’s capabilities, we will create a Postgres server in Microsoft’s Azure Cloud. Code examples will be provided to help the learning process go more smoothly. In this C# programming tutorial, we will demonstrate how a developer can access the PostgreSQL database system using C#. Postgres is also one of the most important relational database systems in the open-source world. PostgreSQL is a free and open-source relational database management system (RDBMS).
