Invalid object name 'userdatabase' 

입니다

그리고 이것은 cs 코드입니다 :

using System;  
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using System.Data.SqlClient; 


public partial class Default2 : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     if (Page.IsPostBack == true) 
     { 
      Label1.Text = ("**Registration Succesful"); 
     } 
    } 
    protected void Button1_Click(object sender, EventArgs e) 
    { 
     SqlConnection User = new SqlConnection("Data Source=TOSHIBA0007\\TESTSERVER;Integrated Security=True"); 
     { 
      SqlCommand xp = new SqlCommand("Insert into userdatabase(Username, Email, Password)Values(@Username, @Email, @Password)", User); 
      xp.Parameters.AddWithValue("@Username", InputUsername.Text); 
      xp.Parameters.AddWithValue("@Email", InputEmail.Text); 
      xp.Parameters.AddWithValue("@Password", InputPassword.Text); 

      User.Open(); 
      xp.ExecuteNonQuery(); 
      User.Close(); 

      if (IsPostBack) 
      { 
       InputUsername.Text = ""; 
       InputPassword.Text = ""; 
       InputEmail.Text = ""; 
       VerifyPassword.Text = ""; 

      }  
     }    
     } 
    } 

나는 이러한 종류의 오류를 초보자로서 도움이된다고 생각합니다.

는

SqlCommand xp = new SqlCommand("Insert into userdatabase(Username, Email, 
    Password)Values(@Username, @Email, @Password)", User); 
       xp.Parameters.AddWithValue("@Username", InputUsername.Text); 
       xp.Parameters.AddWithValue("@Email", InputEmail.Text); 
       xp.Parameters.AddWithValue("@Password", InputPassword.Text);
