Description of the problem:

When trying to connect to a remote server using Visual Studio 2022, I receive the following error:

                X     A service error occurred. 

I have already searched for help online, but I have not been able to find a solution that works for me. I have tried the following solutions:

  • Disabling script debugging in Internet Options.

None of these solutions have worked.

  • I have tried with different user accounts on the server.

Question:

Has anyone encountered this error before? What can I do to fix it?

I appreciate any help you can provide.

  • Operating system you are using.
  • Version of Visual Studio 2022 you are using.

    Hi @Roberto C , Welcome to Microsoft Q&A,

    Using C# to connect to a remote SQL Server database can be achieved through the SqlConnection class.

    using System;
    using System.Data.SqlClient;
    
    class Program
    {
        static void Main()
        {
            // Connection string
            string connectionString = "Server=your_server_address;Database=your_database_name;User Id=your_username;Password=your_password;";
    
            // Create a connection object
            using (SqlConnection connection = new SqlConnection(connectionString))
            {
                try
                {
                    // Open the connection
                    connection.Open();
                    Console.WriteLine("Connection successful!");
    
                    // Create an SQL command
                    string query = "SELECT * FROM YourTableName";
                    SqlCommand command = new SqlCommand(query, connection);
    
                    // Execute the command and read the data
                    using (SqlDataReader reader = command.ExecuteReader())
                    {
                        while (reader.Read())
                        {
                            Console.WriteLine($"{reader["ColumnName"]}");
                        }
                    }
                }
                catch (SqlException ex)
                {
                    Console.WriteLine("Database operation error: " + ex.Message);
                }
                finally
                {
                    // Ensure the connection is closed
                    if (connection.State == System.Data.ConnectionState.Open)
                    {
                        connection.Close();
                    }
                }
            }
        }
    }
    

    When using SQL commands, try to use parameterized queries to prevent SQL injection attacks. For example:

    string query = "SELECT * FROM YourTableName WHERE ColumnName = @value";
    SqlCommand command = new SqlCommand(query, connection);
    command.Parameters.AddWithValue("@value", someValue);
    

    Make sure the firewall on the server where the remote SQL Server resides is configured to allow connections from your client IP address. By default, SQL Server uses TCP port 1433.

    Best Regards,

    Jiale
