SqlCeException

A connection-level error occurred while opening the connection.

This method establishes a new connection to the data source.

NoteNote:

If the SqlCeConnection goes out of scope, it is not closed. You must explicitly close the connection by calling Close or Dispose.

The following example creates a SqlCeConnection, opens it, executes a query, and then closes the connection.

SqlCeConnection conn = null;

try
{
    conn = new SqlCeConnection("Data Source = MyDatabase.sdf; Password ='<pwd>'");
    conn.Open();

    SqlCeCommand cmd = conn.CreateCommand();
    cmd.CommandText = "INSERT INTO Customers ([Customer ID], [Company Name]) Values('NWIND', 'Northwind Traders')";

    cmd.ExecuteNonQuery();
}
finally
{
    conn.Close();
}
