我在 c# 控制台应用程序中的这个插入存储过程中做错了什么

Question

我在 c# 控制台中制作了一个应用程序，它读取 xml 文件并插入一些需要存储的关键属性。 我正在尝试使用进入我的 Program.cs 中调用的 DataAccess class 的存储过程来做到这一点。 我将首先展示我的 DataAccess class 以及我如何制作我的 SP_Insert

class DataAccess
{
    SqlConnection connection = null;

    public DataAccess()
    {
        connection = new SqlConnection(@"Persist Security Info=False;Integrated Security=true; Initial Catalog=Teste;Data Source=Teste;Server=localhost\sqlexpress");
    }

    private void ManageConnectionState()
    {
        if (connection == null || connection.ConnectionString.Equals(""))
        {
            connection = new SqlConnection(@"Persist Security Info = False; Integrated Security = true; Initial Catalog = Teste; Data Source = Teste; Server = localhost\sqlexpress");
            connection.Open();
        }
        else
          if (connection.State.Equals(ConnectionState.Closed))
        {
            connection.Open();
        }
        else
        {
            connection.Dispose();
            connection.Close();
        }
    }

    #region Insert
    public void SP_Insert(string XMLPath, string XMLName, string BatchClassName, string BatchName, string BatchDescription, string Error, string ErrorImagePath, string Done)
    {
        try
        {
            ManageConnectionState();
            SqlCommand command = new SqlCommand("Sp_Insert", connection);
            command.CommandType = CommandType.StoredProcedure;
            command.Parameters.AddWithValue("@XMLPath", XMLPath);
            command.Parameters.AddWithValue("@XMLName", XMLName);
            command.Parameters.AddWithValue("@BatchClassName", BatchClassName);
            command.Parameters.AddWithValue("@BatchName", BatchName);
            command.Parameters.AddWithValue("@BatchDescription", BatchDescription);
            command.Parameters.AddWithValue("@Error", Error);
            command.Parameters.AddWithValue("@ErrorImagePath", ErrorImagePath);
            command.Parameters.AddWithValue("@Done", Done);
            command.ExecuteScalar();
        }
        catch (Exception ex)
        {
            Console.WriteLine("Erro: " + ex.Message);
        }
        finally
        {
            ManageConnectionState();
            connection.Close();
        }

    }
    #endregion
}

}

我认为这部分都是正确的，接下来的两个是我不知道的现在这是我的 Progam.cs 文件

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Data;

namespace XMLReaderConsoleAPP1
{
    class Program
    {
        static void Main()
        {
            DataAccess da = new DataAccess();
            try
            {
                var path = @"C:\XMLFiles";
                DirectoryInfo di = new DirectoryInfo(path);

                foreach (var file in Directory.GetFiles(path, "*.xml"))
                {
                    ProcessFile(file);
                }
                Console.ReadKey();
            }
            catch (Exception ex)
            {
                Console.WriteLine("Erro: {0}", ex.Message);
                return;
            }

            void ProcessFile(string Filename)
            {
            bool temErro = false;
            Console.WriteLine("A processar xml: " + Filename);
            XmlDocument xml = new XmlDocument();
            xml.Load(Filename);

            //XmlNodeList xnLista = xml.SelectNodes(@"//Pages/Page");
            //Console.WriteLine($"Selected {xnLista.Count} nodes");



            XmlNodeList xnLista3 = xml.SelectNodes(@"//ImportSession/Batches");
            XmlNodeList xnLista2 = 
            xml.SelectNodes(@"//ImportSession/Batches/Batch/Documents/Document/Pages/Page");
            //Console.WriteLine($"Selected {xnLista3.Count} nodes");
            //Console.WriteLine($"Selected {xnLista2.Count} nodes");
            //int j = 0;
            foreach (XmlNode xn in xnLista2)
            {
                //Console.WriteLine($"{++i} {xn.Name}: {xn.Attributes["ImportFileName"].Value}");
                string processed = "@//Batch[Processed]";
                //Console.WriteLine($"{++j} {xn.Name}: {xn.Attributes["Value"].Value}");
                string BatchClassName = xn.Attributes["BatchClassName"]?.Value;
                string BatchName = xn.Attributes["Name"]?.Value;
                string BatchDescription = xn.Attributes["Description"]?.Value;
                //string process = xn.Attributes["Processed"]?.Value;
                string error = xn.Attributes["ErrorMessage"]?.Value;
                string errorImagePath = xn.Attributes["ErrorCode"]?.Value;
                if (!string.IsNullOrEmpty(processed)) //xml já foi processado
                {
                    if (!string.IsNullOrEmpty(error))
                    {
                        string page = xn.Attributes["ImportFileName"].Value;
                        Console.WriteLine("Página com erro: " + page);
                        temErro = true;
                        da.SP_Insert(page, Filename, BatchClassName, BatchName, BatchDescription, 
                        error, errorImagePath, processed);

                       
                    }
                }
            }

            if (temErro)
                Console.WriteLine("Ficheiro com erro: " + Filename);
            else
                Console.WriteLine("Ficheiro processado: " + Filename);

            //Console.WriteLine(Filename);
        }


    }

}

}

我一直在使用 xn.Attributes 来获取我需要的信息，但由于某种原因，某些字符串没有返回值（从 BatchClassName 到结尾）

我觉得很奇怪，因为前两个确实显示了信息。

现在这是我的存储过程

     USE [Teste]
   GO

BEGIN
Insert into T_XMLFiles (XMLPath, XMLName, BatchClassName, BatchName, BatchDescription, Error, ErrorImagePath, Done)
Values(@XMLPath, @XMLName, @BatchClassName, @BatchName, @BatchDescription, @Error, @ErrorImagePath, @Done)
END

我还将留下一个 xml 文件的示例，因为它们都遵循相同的结构
