System.Data.SqlClient.SqlException C＃

Question

When I am using cmd.ExecuteNonQuery() it doesn`t work and shows me the next error:

    SqlCommand newUser = new SqlCommand("INSERT INTO [DinoTable] VALUES(@name,  @height, @heightscale, @weight, @weightscale, @diet, @status, @locationDis, @dayDis, @monthDis, @yearDis, @yourlocation, @dayborn, @monthborn, @yearborn, @Gender, @yourEmail, @yoname, @lastname, @getmoney); ", c);
                newUser.Connection = c;
                newUser.Parameters.AddWithValue("@name", (string)Session["Name"]);
                newUser.Parameters.AddWithValue("@height", Convert.ToDouble(Session["Height"]));
                newUser.Parameters.AddWithValue("@heightscale", (string)Session["HeightScale"]);
                newUser.Parameters.AddWithValue("@weight", Convert.ToDouble(Session["Weight"]));
                newUser.Parameters.AddWithValue("@weightscale", (string)Session["weightscale"]);
                newUser.Parameters.AddWithValue("@diet", (string)Session["diet"]);
                newUser.Parameters.AddWithValue("@status", (string)Session["status"]);
                newUser.Parameters.AddWithValue("@locationDis", (string)Session["locationDis"]);
                newUser.Parameters.AddWithValue("@dayDis", Convert.ToInt32(Session["dayDis"]));
                newUser.Parameters.AddWithValue("@monthDis", (string)(Session["monthDis"]));
                newUser.Parameters.AddWithValue("@yearDis", Convert.ToInt32(Session["yearDis"]));
                newUser.Parameters.AddWithValue("@yourlocation", (string)Session["yourlocation"]);
                newUser.Parameters.AddWithValue("@dayborn", Convert.ToInt32(Session["dayborn"]));
                newUser.Parameters.AddWithValue("@monthborn", (string)(Session["monthborn"]));
                newUser.Parameters.AddWithValue("@yearborn", Convert.ToInt32(Session["yearborn"]));
                newUser.Parameters.AddWithValue("@Gender", (string)Session["Gender"]);
                newUser.Parameters.AddWithValue("@yourEmail", (string)Session["yourEmail"]);
                newUser.Parameters.AddWithValue("@yoname", (string)Session["YourName"]);
                newUser.Parameters.AddWithValue("@lastname", (string)Session["YourLastName"]);
                newUser.Parameters.AddWithValue("@getmoney", 0);
c.Open()
newUser.ExecuteNonQuery(); 
c.Close();

the full error:

An exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll but was not handled in user code

Additional information: The parameterized query '(@name nvarchar(5),@height float,@heightscale nvarchar(4),@weigh' expects the parameter '@monthDis', which was not supplied.

Answer 1

It seems that the monthDis is a string and the yearDis and dayDis are integers. Could it be that monthDis is also an integer?

If so, please try changing :

newUser.Parameters.AddWithValue("@monthDis", (string)(Session["monthDis"]));

to:

newUser.Parameters.AddWithValue("@monthDis", Convert.ToInt32(Session["monthDis"]));
