that are not threadsafe. Even if your code is not explicitly creating multiple threads, you have to be careful of situations where multiple threads may be used internally. I noticed that your call stack shows that the SqlDataReader.Close call is coming from your Finalize method (it's directly coming from Dispose, but Dispose is being called by Finalize). It is not safe to call any managed objects in Finalize, because it is called non-deterministically by the garbage collector on a separate thread. The SqlDataReader.Close documentation explicitly calls this out: SqlDataReader.Close Method http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.close.aspx Caution  Do not call Close or Dispose on a Connection, a DataReader, or any other managed object in the Finalize method of your class. In a finalizer, you should only release unmanaged resources that your class owns directly. If your class does not own any unmanaged resources, do not include a Finalize method in your class definition. For more information, see Garbage Collection. You should explicitly close the SqlDataReader when you are done using it, before finalization. If you do that and are still running into proble

Apr 20, 2006 03:19 PM|Ivoryzion|LINK VS2k5 Win2k3 IIS6 .NET 2.0 In my ASP.NET 2.0 app I create and https://social.msdn.microsoft.com/Forums/en-US/b23d8492-1696-4ccb-b4d9-3e7fbacab846/internal-net-framework-data-provider-error-1?forum=adodotnetdataproviders open an SQL connection in the page's constructor and call Dispose() in the destructor. The SQLConnection object is a class member of the page. This page makes heavy use of the SQLConnection object so I felt opening and closing in the constructor/destructor respectively was good design. I know this doesn't take full advantage of connection pooling. Any design input would be very much https://forums.asp.net/t/983824.aspx?Internal+Net+Framework+Data+Provider+error+1+ appreciated. Here's the destructor code: /// Destructor ~Officer() { if( m_objConn != null ) m_objConn.Dispose(); // <-- Exception occurrs here. } /// End Destructor When running this particular page through some testing I get the following exception in the destructor at the "m_objConn.Dispose();" line: System.InvalidOperationException was unhandled Message="Internal .Net Framework Data Provider error 1." Source="System.Data" StackTrace: at System.Data.ProviderBase.DbConnectionInternal.PrePush(Object expectedOwner) at System.Data.ProviderBase.DbConnectionPool.PutObject(DbConnectionInternal obj, Object owningObject) at System.Data.ProviderBase.DbConnectionInternal.CloseConnection(DbConnection owningObject, DbConnectionFactory connectionFactory) at System.Data.SqlClient.SqlConnection.Close() at System.Data.SqlClient.SqlConnection.Dispose(Boolean disposing) at System.ComponentModel.Component.Dispose() at Officer.Finalize() in c:\sys\projects\AddOfficer.aspx.cs:line 46 1) Is this design good/bad? 1) Is this a bug? 2) Do I need a try/catch in a destructor? Is it good programming practice? 3) Why is this happening? 4) What is the meaning of life? Any help is appreciated.

Where is source of error? There is http://www.codeproject.com/Questions/1070919/Error-System-InvalidOperationException-Internal-Ne a class library DLL created by another person. I used C# (VS 2005 Professional Edition) and SQL Server 2005 Express Edition and also used Visual SourceSafe 6.0.In this class,There internal .net is a constructor and destructor in the destructor it calls the CloseConnection() method where the error occurs.Code:private void CloseConnection() {if (m_Connection != null) {try {// Check if connection is already closed, if not, then close itif (m_Connection.State != ConnectionState.Closed)m_Connection.Close(); <<---Error Occurs here// Dispose the connection object and set it to null to release resources used by the objectm_Connection.Dispose();m_Connection = null;}catch internal .net framework {throw;}}}***RESOLVED*** I created new class to do same function without using destructor to close connection. I am puzzled why this class works with version 1.1 and SQL 2000...Confuse?:confused:denpsia -----------------------------------------------------------------------------------------Please make sure if problem in your post is solved, add Resolved icon and/or add "[Resolved]" in your title on first post.

I'm not 100% sure but I think there might be a problem with trying to close a connection that has a ConnectionStatus other then Open.
