Insert datetime value in sql database with c#

To insert a DateTime value into an SQL database using C#, you typically use parameterized queries to ensure security and avoid SQL injection vulnerabilities. Here's an example using SQL Server and ADO.NET:

using System; using System.Data.SqlClient; class Program { static void Main() { // Connection string string connectionString = "Data Source=YourServer;Initial Catalog=YourDatabase;Integrated Security=True"; // DateTime value to insert DateTime dateTimeValue = DateTime.Now; // SQL query with parameter string query = "INSERT INTO YourTable (ColumnName) VALUES (@DateTimeValue)"; using (SqlConnection connection = new SqlConnection(connectionString)) { // Open the connection connection.Open(); using (SqlCommand command = new SqlCommand(query, connection)) { // Add parameter command.Parameters.AddWithValue("@DateTimeValue", dateTimeValue); // Execute the query int rowsAffected = command.ExecuteNonQuery(); if(rowsAffected > 0) { Console.WriteLine("DateTime value inserted successfully."); } else { Console.WriteLine("Insert operation failed."); } } } } }

Make sure to replace 'YourServer', 'YourDatabase', 'YourTable', and 'ColumnName' with your actual SQL Server details and table/column names.

This code connects to the SQL Server database, creates a parameterized query to insert a DateTime value, and executes it using ExecuteNonQuery() method of SqlCommand. It's good practice to wrap your SqlConnection, SqlCommand, and any other objects implementing IDisposable within a using block to ensure proper disposal and release of resources.
