Une exception de type « System.ArgumentException » est survenue dans System.Data.dll mais n'a pas été traitée dans le code utilisateur

Question

Il indique en outre que la procédure ou la fonction spAddOrganization attend paramètre Organizational_Number qui n'a pas été fourni

IEnumerable<OrganizationalDetails> OrganizationalDetails 
{ 
    get 
    { 
     string connectionString = ConfigurationManager.ConnectionStrings["OnlineDBContext"].ToString(); 
     List<OrganizationalDetails> organization = new List<OrganizationalDetails>(); 

     using (SqlConnection con = new SqlConnection(connectionString)) 
     { 
      SqlCommand cmd = new SqlCommand("spAddOrganization", con); 
      cmd.CommandType = CommandType.StoredProcedure;` 
      con.Open(); 

      SqlDataReader myreader = cmd.ExecuteReader(); 

      while(myreader.Read()) 
      { 
       OrganizationalDetails organize = new OrganizationalDetails(); 
       organize.Organizational_Id = Convert.ToInt32(myreader["Organizational_Id"].ToString()); 
       organize.Organizational_Number = myreader["Organizational_Number"].ToString(); 
       organize.Location = myreader["Location"].ToString(); 
       organize.Organization_Address = myreader["Organizational_Address"].ToString(); 
       organize.TelephoneNo_Org = myreader["TelephoneNo_Org"].ToString(); 
       organize.Organizational_Name = myreader["Organizational_Name"].ToString();`ganizational_Name = myreader["Organizational_Name"].ToString();_Name = myreader["Organizational_Name"].ToString(); 
       organize.Administrator_Name = myreader["Administrator_Name"].ToString(); 
       organization.Add(organize); 
      } 
     } 
     return organization; 
    } 
} 

La stockée procédure est la suivante:

ALTER PROCEDURE [dbo].[spAddOrganization] 
    @Organizational_Number nvarchar(50), 
    @Location nvarchar(50), 
    @Organizational_Address nvarchar(50), 
    @TelephoneNo_Org nvarchar(50), 
    @Organizational_Name nvarchar(50), 
    @Administrator_Name nvarchar(50) 
AS 
BEGIN 
    INSERT INTO Organization_Details(Organizational_Number,Location,Organizational_Address,TelephoneNo_Org,Organizational_Name,Administrator_Name) 
    VALUES(@Organizational_Number,@Location,@Organizational_Address,@TelephoneNo_Org,@Organizational_Name,@Administrator_Name) 
END 

Tout semble parfait. J'ai essayé de googler, essayé mais trouvé réponse pas vraiment compréhensible.

Parce que votre stockée Procerure insérer un encart article vous devez passer les arguments comme ceci:

string connectionString = ConfigurationManager.ConnectionStrings["OnlineDBContext"].ToString(); 

using (SqlConnection con = new SqlConnection(connectionString)) 
{ 

    SqlCommand cmd = new SqlCommand("spAddOrganization", con); 
    con.Open(); 
    cmd.CommandType = CommandType.StoredProcedure; 

    SqlParameter[] parameters = new SqlParameter[] 
    { 
     new SqlParameter("@Organizational_Number", organize.Organizational_Number), 
     new SqlParameter("@Location", organize.Location), 
     new SqlParameter("@Organizational_Address", organize.Organization_Address), 
     new SqlParameter("@TelephoneNo_Org", organize.TelephoneNo_Org), 
     new SqlParameter("@Organizational_Name", organize.Organizational_Name), 
     new SqlParameter("@Administrator_Name", organize.Administrator_Name) 
    }; 
    cmd.Parameters.AddRange(parameters); 
    int retorno = cmd.ExecuteNonQuery(); 
}
