sqlce c#

Question

Bonjour a tous

Voila encore un probleme du moin je le pense car l'erreurs de ce code  est toujour la meme.

string connectionString; 
string fileName = "MyRV.sdf"; 
string password = "Daniel"; 
if (File.Exists(fileName)) 
{ 
File.Delete(fileName); 
}
connectionString = string.Format("DataSource=\"{0}\"; Password=\"{1}\"", fileName, password); 
 SqlCeEngine en = new SqlCeEngine(connectionString); 
en.CreateDatabase();
en.Dispose();
 SqlCeConnection cn = new SqlCeConnection(ConnectString()); 
 if (cn.State==ConnectionState.Closed) 
{
cn.Open();
} 
SqlCeCommand cmd;

l'erreur vient de la ligne si-dessous apres Create Table
Existe il un facon de faire sans prob. pour la selection a partir du monthCalendar control 
string sql = "create table " + monthCalendar.SelectionEnd.ToShortDateString() + " (Heures nvarchar (8) not null, Descriptions nvarchar (247))"; 
cmd = new SqlCeCommand(sql, cn); 
 try 
{
cmd.ExecuteNonQuery();
}
catch (SqlCeException sqlexception) 
{ 
MessageBox.Show(sqlexception.Message, "Oops.", MessageBoxButtons.OK, MessageBoxIcon.Error); 
} 
catch (Exception ex) 
{ 
MessageBox.Show(ex.Message, "Oops.", MessageBoxButtons.OK, MessageBoxIcon.Error); 
}
finally
{
cn.Close();
}

 

MERCI!
