Hello,

I've c# app, I'm comparing in query between dates ,it doesn't recognize the comparison .The error is
An expression of non-boolean type specified in a context where a condition is expected, near '10/31/2012 09:00:00 م'.
Here's my code

C#
string x=textBox1.Text;
string y=textBox1.Text;

DateTime fro=Convert.ToDateTime (x);
DateTime to=Convert.ToDateTime (y);
SqlConnection con = new SqlConnection(@"Data Source=.\Ahmed;Initial Catalog=Market;Integrated Security=True");
cmd=new SqlCommand ( "SELECT dat , product_id FROM  market where dat >= '" + fro + "' and '"+to+"' ",con);
con.Open();
dr = cmd.ExecuteReader();
DataSet sd = new DataSet(); ;

while (dr.Read())
{
    DateTime d = (DateTime)dr["dat"];
    if (d >= fro && d <= to)
    {

    }
}
dr.Close();


How to send the result of datareader to dataset?

When answering a question please:
  1. Read the question carefully.
  2. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
  3. If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
  4. Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.
