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(); } ```
