There must be something else going on in your code, since that is a valid statement. Please check the exact line that the error occurs on, and show more of the surrounding code.

here is my complete code

in code.aspx.cs

[WebMethod]
public static bool register(string rusrid, string rname, string raddress, string rcity,string rdistrict,string rstate,int rpin,string rlanph,string rmob,string rgen, string remail,string rpass)
{

bool msg = false;
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
con.Open();
SqlCommand cmd = new SqlCommand("user_reg", con);
cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.AddWithValue("@custid", rusrid);
cmd.Parameters.AddWithValue("@name", rname);
cmd.Parameters.AddWithValue("@address", raddress);
cmd.Parameters.AddWithValue("@city", rcity);

cmd.Parameters.AddWithValue("@district", rdistrict);
cmd.Parameters.AddWithValue("@state", rstate);
cmd.Parameters.AddWithValue("@pin", rpin);
cmd.Parameters.AddWithValue("@mobile", rmob);

cmd.Parameters.AddWithValue("@landphone", rlanph);
cmd.Parameters.AddWithValue("@email", remail);
cmd.Parameters.AddWithValue("@gender", rgen);
cmd.Parameters.AddWithValue("@password", rpass);
//cmd.Parameters.AddWithValue("@Jdate", System.DateTime.Now);
//cmd.Parameters.Add("@Jdate", SqlDbType.Date).Value = String.Format("{0:dd/MM/yyyy}", DateTime.Now);
cmd.Parameters.Add("@Jdate", SqlDbType.Date).Value = DateTime.Now.ToString("dd/MM/yyyy");

SqlDbType.Date should be taking a Date value, not a String. See SqlDbType Enumeration (System.Data)[^].

Solution 1

You can try this

C#

cmd.Parameters.Add("@Jdate", SqlDbType.Date).Value=String.Format("{0:dd/MM/yyyy}", DateTime.Now);

Hi I have tried your solution you gave me but I am now getting an error like this:

"DateTime.Now is a namespace but it is used like a variable"

Richard Deeming · Answer 2 · 2017-05-04T02:41:00

Simple: don't call ToString at all.

You've declared your parameter as SqlDbType.Date. That means it expects a date value, not a string.

Either:

cmd.Parameters.AddWithValue("@Jdate", System.DateTime.Today);

or:

cmd.Parameters.Add("@Jdate", SqlDbType.Date).Value = DateTime.Today;

will work.

Quote:
"DateTime.Now is a namespace but it is used like a variable"

That suggests you've either created a file with a namespace of DateTime.Now, or you're missing the using System; directive from the top of your file.

If you've created a file in that namespace, I'd strongly suggest you change it. Creating namespaces with the same name as a built-in type is not a good idea.
