Question

我正在开发一个应用程序，将一些.msg文件的内容记录到SQL数据库中。

.msg文件也来自SMS服务器，只是为了解决我遇到的问题。

每次我在服务器上运行脚本时，我都会得到“提供的文件不是有效的IStorage”，谷歌似乎对这个问题毫无结果，这让我很生气！

我也在使用这个库：https://github.com/Sicos1977/MSGReader

using MsgReader.Outlook;
using System;
using System.Data.SqlClient;
using System.IO;
using System.Linq;

namespace OutboxSMS
{
class Program
{
    static void Main(string[] args)
    {
        PostmsgtoSQL();
        Console.ReadLine();
    }

    static bool Filecreated = true;

    public static void OnChanged(object source, FileSystemEventArgs e)
    {
        Filecreated = true;
    }

    public static void PostmsgtoSQL()
    {
        var directory = new DirectoryInfo("C:\\ProgramData\\Felltech Ltd\\OutboxSMSXX\\SMSTextSent");
        var myFile = directory.GetFiles().OrderByDescending(f => f.LastWriteTime).First();
        var filepath = myFile.ToString();

        //File System Watching
        FileSystemWatcher FSW = new FileSystemWatcher(directory.ToString(), ".log");
        FSW.Created += new FileSystemEventHandler(OnChanged);
        FSW.EnableRaisingEvents = true;
        //below is broken :<
        using (var msg = new Storage.Message(@filepath))
        {
            //Grab .msg headers
            var Id = msg.Id;
            var datetime = msg.CreationTime;
            var from = msg.Sender;
            var sentOn = msg.SentOn;
            var recipientsTo = msg.GetEmailRecipients(Storage.Recipient.RecipientType.To, false, false);
            var subject = msg.Subject;
            var messagebody = msg.BodyRtf;
            //broken to here
            if (Filecreated == true)
            {
                //SQL Wizardry
                SqlConnection db = new SqlConnection();
                db.ConnectionString = "Server=Dev-SQL;Database=AshTest;Trusted_Connection=true";
                String query = "INSERT INTO dbo.SMSLog (ID,toaddress,fromaddress,subject,datetime,messagebody) VALUES(@Id,@toaddress,@fromaddress, @subject, @datetime.)";
                db.Open();
                SqlCommand command = new SqlCommand(query, db);
                command.Parameters.AddWithValue("@ID", Id);
                command.Parameters.AddWithValue("@toaddress", recipientsTo);
                command.Parameters.AddWithValue("@fromaddress", from);
                command.Parameters.AddWithValue("@subject", subject);
                command.Parameters.AddWithValue("@datetime", datetime);
                command.Parameters.AddWithValue("@messagebody", messagebody);
                command.ExecuteNonQuery();
                db.Close();
                db.Dispose();
            }
        }
    }
}
}

此库调用StgIsStorageFile方法，但丢弃结果。在库中更改这两行，如下所示：

if (NativeMethods.StgIsStorageFile(storageFilePath) != 0)
{
   throw new ArgumentException("The provided file is not a valid IStorage", "storageFilePath");
}

对于类似的东西：

int result = NativeMethods.StgIsStorageFile(storageFilePath);
if (result != 0)
{
   throw new ArgumentException($"The provided file is not a valid IStorage. Result={result}", "storageFilePath");
}

返回值在here中进行了描述，应该可以帮助您找到正在发生的事情。

提供的文件不是有效的IStorage
