Question

string strCon = ConfigurationManager.ConnectionStrings["conCTSystem"].ConnectionString;
SqlConnection conSchedule = new SqlConnection(strCon);

conSchedule.Open();

SqlCommand cmdSchedule = new SqlCommand("Select Day From Schedule Where RoomNumber=@roomNumber", conSchedule);
cmdSchedule.Parameters.AddWithValue("@roomNumber", ddlRoomNumber.SelectedValue); //MatchWithDropDownList

using (SqlDataAdapter da = new SqlDataAdapter(cmdSchedule))
{
    DataSet ds = new DataSet();
    da.Fill(ds);

    if (ds.Tables.Count > 0)
    {
       string ReturnDay = ds.Tables[0].Rows[0]["Day"].ToString();

       if (ReturnDay == "Monday")
       {
          Label1.Text = "abc";
       }
       else
       {
          Label1.Text = "cde";
       }
    }
 }

任何人都可以帮我解决这个问题吗？我是使用asp.net c＃的新学习者，我面临的问题是当ReturnDay等于Monday并且应该显示“abc”结果但输出显示给我的是“cde” ”

Answer 1

试试这个：

if (ReturnDay.Trim().Equals("Monday"))
{
    Label1.Text = "abc";
}

或

if (ReturnDay.Trim().Equals("Monday",StringComparison.InvariantCultureIgnoreCase))
{
    Label1.Text = "abc";
}

从数据库中检索数据并在asp.net中比较检索到的结果c＃
