using System.Data.SqlClient;

// Define the connection string
string connectionString = "Data Source=MyServer;Initial Catalog=MyDatabase;Integrated Security=True";

// Define the UPDATE statement with parameters
string query = "UPDATE MyTable SET Column1=@Value1, Column2=@Value2 WHERE ID=@ID";

// Create a new SqlConnection using the connection string
using (SqlConnection connection = new SqlConnection(connectionString))
{
    // Open the connection
    connection.Open();
    
    // Create a new SqlCommand using the query and the SqlConnection
    using (SqlCommand command = new SqlCommand(query, connection))
    {
        // Add parameters to the SqlCommand
        command.Parameters.AddWithValue("@Value1", "New Value 1");
        command.Parameters.AddWithValue("@Value2", "New Value 2");
        command.Parameters.AddWithValue("@ID", 1);
