HasRows return value is inconsistent

@jovana writes (split from #327):

I want to add something to the HasRows property.
I found a very strange behavior.

The value of MySqlDataReader.HasRows has changed the moment you request the value of the property. In my opinion it should always the same, right? It seems like it only changed the first and second time you request the value.

Dim rs As MySqlDataReader = cmd.ExecuteReader
Dim HasRows As Boolean
HasRows = rs.HasRows    ' <-- this will returns True (this is good)
HasRows = rs.HasRows    ' <-- this will returns False (why, what is changed on the first call?)
HasRows = rs.HasRows    ' <-- this will returns True (again, this is good)
HasRows = rs.HasRows    ' <-- this will returns True (again, now it keeps True al the checkes)

Thanks for the fix!

Fixed in 0.28.0.

I don't think this is fixed, I'm getting the same behavior on the latest version

@Topcoder01 There's a test that verifies that the OP's bug is fixed:

MySqlConnector/tests/SideBySide/QueryTests.cs

Lines 817 to 847 in 518513b

	[Fact]
	public void HasRowsRepeated()
	{
	m_database.Connection.Execute(@"drop table if exists has_rows;
	create table has_rows(value int not null);
	insert into has_rows(value) values(1),(2),(3);");
	using (var cmd = m_database.Connection.CreateCommand())
	{
	cmd.CommandText = "select * from has_rows where value = 1;";
	using (var reader = cmd.ExecuteReader())
	{
	Assert.True(reader.HasRows);
	Assert.True(reader.HasRows);
	Assert.True(reader.HasRows);
	Assert.True(reader.HasRows);
	Assert.True(reader.Read());
	Assert.True(reader.HasRows);
	Assert.True(reader.HasRows);
	Assert.True(reader.HasRows);
	Assert.False(reader.Read());
	Assert.True(reader.HasRows);
	Assert.True(reader.HasRows);
	Assert.True(reader.HasRows);
	}
	}
	}

Do you have steps to reproduce the problem?
