Do I have to Close() a SQLConnection before it gets disposed?

asp.net, c#, sqlcommand, sqlconnection, using

Solution

Since you have a using block, the Dispose method of the SQLCommand will be called and it will close the connection:

// System.Data.SqlClient.SqlConnection.Dispose disassemble
protected override void Dispose(bool disposing)
{
    if (disposing)
    {
        this._userConnectionOptions = null;
        this._poolGroup = null;
        this.Close();
    }
    this.DisposeMe(disposing);
    base.Dispose(disposing);
}

Problem

Per my other question here about Disposable objects, should we call Close() before the end of a using block? ``` using (SqlConnection connection = new SqlConnection()) using (SqlCommand command = new SqlCommand()) { command.CommandText = "INSERT INTO YourMom (Amount) VALUES (1)"; command.CommandType = System.Data.CommandType.Text; connection.Open(); command.ExecuteNonQuery(); // Is this call necessary? connection.Close(); } ```
