FbCommand closes the ActiveReader when is disposed. This behavior is diferent
from other DbCommand implemetations
------------------------------------------------------------------------------------------------------------------
Key: DNET-89
URL: http://tracker.firebirdsql.org/browse/DNET-89
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 2.1.0 Beta 3
Environment: Windows XP
Reporter: Fabiano Rezende
Assignee: Carlos Guzman Alvarez
>From FbCommand.cs:
protected override void Dispose(bool disposing)
{
lock (this)
{
if (!this.disposed)
{
try
{
// If there are an active reader close
it
this.CloseReader(); <<<======
.
.
.
this.disposed = true;
}
finally
{
base.Dispose(disposing);
}
}
}
}
IMHO all ADO.NET provider must have the same behavior.
For example:
The Microsoft.Practices.EnterpriseLibrary.Data.Database has the following
method that returns a DataReader
public IDataReader ExecuteReader(string storedProcedureName, params object[]
parameterValues)
{
using (DbCommand command =
GetStoredProcCommand(storedProcedureName, parameterValues))
{
return ExecuteReader(command);
} // << command is disposed here and the returned DataReader will
be closed
}
