フォームを作成して INSERT すると、このエラーが発生しました。これはコードビハインドのコードです。
protected void btnSave_Click(object sender, EventArgs e)
{
string Selected = category_ddl.SelectedValue;
lb_date.Text = System.DateTime.Now.ToLongDateString();
process();
}
private void process()
{
string connectionString = @"Data Source=.\SQLEXPRESS;AttachDbFilename= |DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True";
string sql = "INSERT INTO News (date_time,title,author,source,category,description,) VALUES (@date, @title, @author,@source,@Selected,@description)";
SqlConnection conn = new SqlConnection(connectionString);
conn.Open();
SqlCommand cmd = new SqlCommand(sql, conn);
cmd.Parameters.AddWithValue("@date", lb_date.Text.ToString());
cmd.Parameters.AddWithValue("@title", title_tb.Text.ToString());
cmd.Parameters.AddWithValue("@author", author_tb.Text.ToString());
cmd.Parameters.AddWithValue("@source", source_tb.Text.ToString());
cmd.Parameters.AddWithValue("@Selected", category_ddl.Text.ToString());
cmd.Parameters.AddWithValue("@description", desc_tb.Text.ToString());
cmd.ExecuteNonQuery();
conn.Close();
}
これは私のエラーです：
Server Error in '/' Application.
