Create a Excel File and Send by email with Microsoft Graph

I am triying to create an Excel file and then send by email using my microsft email adress using Microsft Graph.
If the only thing that i do is send an email works fine, but if create the excel and then try send email using the same code stops working, no errors, simply stop working.
This is my code:

If i execute this first call to my method SenMailUsingMicrosoftGraph works fine and sends an email. But if i call again to SenMailUsingMicrosoftGraph after creating the Excel, the program stops when arrives to:
var msgResult = await graphClient.Users["myemail#mycompany.com"].MailFolders.Drafts.Messages
.Request()
.WithMaxRetry(9)
.AddAsync(message);
Any suggestions?

Make your code really async. Now your program doesn't wait for the response from Graph API and ends immediately after the second call of SenMailUsingMicrosoftGraph.
Use static async Task Main(string[] args), private static async Task SenMailUsingMicrosoftGraph and await before SenMailUsingMicrosoftGraph.
static async Task Main(string[] args)
{
List<String> Destinations = new List<string>() { "myemail#mycompany.com" };
List<string> Cc = new List<string>();
List<System.IO.FileInfo> Filess = new List<System.IO.FileInfo>();
List<Solds> lstSolds = GetData();
await SenMailUsingMicrosoftGraph(Destinations, Cc, "", "Text of the Body", "title of the mail", Filess);
// GenerateExcel creates a Excel File (i use ClosedXML) and retuns a FileInfo
Files.Add(GenerateExcel(lstSolds));
await SenMailUsingMicrosoftGraph(Destinations, Cc, "", "Text of the Body", "title of the mail", Filess);
}
private static async Task SenMailUsingMicrosoftGraph
{
...
}

Whilst debugging, go to 'Exception settings' and click on the box 'Common Language Runtime Exception' so that it turns into a checkmark.
You've probably disabled the specific error being thrown.
After this you'll need to restart debugging.

Using multiple channels, what am I doing wrong?

I want to create an array of Tasks, called listTask, with each element of listTask is a Task of type A, Task of type A is created by the function Task.WhenAll. then I do await Task.WhenAll(listTask) But the program does not perform the work in the listTask array. I set debug and those tasks were completed, I don't understand why
namespace Ding.LearningNewThings
{
public class MultiChannelTask
{
public static async Task RunMiltipleChannel()
{
ConcurrentDictionary<int, Channel<Position>> _dataChannels = new ConcurrentDictionary<int, Channel<Position>>();
var listPlace = Place.InitData();
var numberOfPlace = listPlace.Count();
for (int i = 0; i < listPlace.Count(); i++)
{
_dataChannels.TryAdd(i, Channel.CreateUnbounded<Position>());
}
Task[] listStationTask = new Task[numberOfPlace];
for (var j = 0; j < numberOfPlace; j++)
{
var listTask = new Task[2];
var placeOuter = listPlace[j];
listTask[0] = Task.Run(async () =>
{
int IndexOfPlace = j;
var place = new Place()
{
ID = placeOuter.ID,
Name = placeOuter.Name
};
Channel<Position> dataChannel;
var r = new Random();
if (_dataChannels.TryGetValue(IndexOfPlace, out dataChannel))
{
var position = new Position()
{
PlaceID = place.ID,
PlaceName = place.Name,
ID = r.Next(1, 100)
};
await dataChannel.Writer.WriteAsync(position);
Console.WriteLine($"Push postion ID {position.ID}, Place ID {position.PlaceID}");
}
});
listTask[1] = Task.Run(async () =>
{
var IndexOfPlace = j;
Channel<Position> dataChannel;
var r = new Random();
if (_dataChannels.TryGetValue(IndexOfPlace, out dataChannel)) {
var position = await dataChannel.Reader.ReadAsync();
Console.WriteLine($"Get postion ID {position.ID}, Place ID {position.PlaceID}");
}
});
listStationTask[j] = Task.WhenAll(listTask);
}
await Task.WhenAll(listStationTask);
}
}
public class Place
{
public int ID { get; set; }
public string Name { get; set; }
public static List<Place> InitData()
{
var listData = new List<Place>();
for (int i = 0; i < 10; i++)
{
var data = new Place()
{
ID = i,
Name = $"Postion{i}",
};
listData.Add(data);
}
return listData;
}
}
public class Position
{
public int ID { get; set; }
public int PlaceID { get; set; }
public string PlaceName { get; set; }
public string Name { get; set; }
public static List<Position> InitData()
{
var listData = new List<Position>();
for (int i = 0; i < 10; i++)
{
var data = new Position()
{
ID = i,
Name = $"Postion{i}"
};
listData.Add(data);
}
return listData;
}
}
}
I seem the task have had done ahead of intended. Sometimes it works, but I don't know why the job always completes without running in the list task code.

Applying a filter to an embedded document, filter out distinct values

So I built out a my filter, on the document and sub document, and then passed that filter into a distinct query. I want to use that query in my cursor but I'm getting an error, FindAsync cannot be inferred from the usage. Try specifying the type arguments explicitly.
I'm very new to Mongodb...any help would be fantastic. This works if I just pass the filter, but I need just distinct documents.
var builder = Builders<newMsg>.Filter;
var filter = builder.Eq("type", "CREATE") & builder.Eq("entities.errorCondition", 14);
// var result = collection.Find(filter).ToList();
IList<newMsg> distinct = collection.Distinct<newMsg>("entities.ID", filter).ToList<newMsg>();
if (distinct.Count > 0)
{
using (IAsyncCursor<newMsg> cursor = await collection.FindAsync(distinct))
{
while (await cursor.MoveNextAsync())
{
IEnumerable<newMsg> batch = cursor.Current;
foreach (newMsg document in batch)
{
//This gives me the entire list as a string
var subDocument = document.Entities;
foreach (var sd in subDocument)
{
//do some stuff
}
}
}
}
}
}
my class files look like this
[BsonIgnoreExtraElements]
internal class newMsg
{
[BsonId]
public ObjectId _id { get; set; }
[BsonElement("type")]
public string Type { get; set; }
[BsonElement("entities")]
public List<entity> Entities { get; set; }
}
[BsonIgnoreExtraElements]
internal class entity : newMsg
{
[BsonElement("errorCondition")]
public double ErrorCondition { get; set; }
[BsonElement("ID")]
public string ID { get; set; }
}

I ended up creating 2 loops, 1 for duplicates and another for distinct values, its not beautiful but it worked.
var builder = Builders<newMsg>.Filter;
var filter = builder.Eq("Type", "CREATE") & builder.Eq("Entities.ErrorCondition", 14) & builder.Eq("MsgRead", false);
var result = collection.Find(filter).ToList();
if (result.Count > 0)
{
//Create a list of distinct msgs, then set msgRead to True, then pass that list to a new filter
var distinctMsg = collection.Distinct(new StringFieldDefinition<newMsg, string>("Entities.ID"), FilterDefinition<newMsg>.Empty).ToList();
foreach (var dm in distinctMsg)
{
var entityID = dm;
var msgUnread = Builders<newMsg>.Filter.Eq("msgRead", false);
var msgUpdate = Builders<newMsg>.Update.Set("msgRead", true);
var msgIsRead = collection.UpdateOne(msgUnread, msgUpdate);
//Create another filter on the distinct messages
CreateDistinctFilter(mongoClient, db, collection, entityID, ec);
}
using (IAsyncCursor<newMsg> cursor = await collection.FindAsync(filter))
{
while (await cursor.MoveNextAsync())
{
IEnumerable<newMsg> batch = cursor.Current;
foreach (newMsg document in batch)
{
//This gives me the entire list as a string
var subDocument = document.Entities;
foreach (var sd in subDocument)
{
//log duplicate msg
}
}
}
}
}
static async void CreateDistinctFilter(MongoClient mongoClient, IMongoDatabase db, IMongoCollection<newMsg> collection, string entityID, string ec)
{
var builder = Builders<newMsg>.Filter;
var distinctFilter = builder.Eq("Entities.ID", entityID) & builder.Eq("MsgRead", true);
var result = collection.Find(distinctFilter).ToList();
using (IAsyncCursor<newMsg> cursor = await collection.FindAsync(distinctFilter))
{
while (await cursor.MoveNextAsync())
{
IEnumerable<newMsg> batch = cursor.Current;
foreach (newMsg document in batch)
{
//This gives me the entire list as a string
var subDocument = document.Entities;
foreach (var sd in subDocument)
{
string DeviceName = sd.Name;
string Title = DeviceName + " Device DOWN";
string Msg = sd.Reason + sd.ID;
string ErrorCondition = ec;
Console.WriteLine("UNIQUE: " + " " + DateTime.Now.ToString("MM/dd/yyyy hh:mm:ss.fff") + Msg );
Console.WriteLine();
}
}
}
}
}
}

How Can I Create One xml file with Multiple XML douments inside from a text file

I am a C# beginner programmer. I have a text file, which is my source, with multiple rows of data. I want to create one xml file with multiple xml documents inside the file. The xml documents are generated from the rows of data in the text file. I can only get one xml document to generate in the A0x.xml file that is created. My code only reads the first row of data and generates one xml document instead to multiple xml documents. Below are 8 rows from the M24EX.txt file. Please help!!

The specified table does not exist[entity]

I have spent hours trying to figure out why my database cannot find the table I have found numerous examples and none have seemed to help. I have created a separate class to handle the database operations so I can use it on multiple pages.
Here is the code
[Table]
public class MatchItem
{
[Column(IsPrimaryKey = true, CanBeNull=false,IsDbGenerated=true)]
public int MatchID { get; set; }
[Column(CanBeNull = false)]
public string MatchNumber { get; set; }
[Column(CanBeNull = false)]
public string EventName { get; set; }
[Column(CanBeNull = false)]
public DateTime Time { get; set; }
[Column(CanBeNull = false)]
public string[] RedTeams { get; set; }
[Column(CanBeNull = false)]
public string[] BlueTeams { get; set; }
[Column(CanBeNull = false)]
public int RedFinal { get; set; }
[Column(CanBeNull = false)]
public int BlueFinal{ get; set; }
}
Here is the Data context
public class MatchDataContext:DataContext
{
public MatchDataContext(string connectionString) :
base(connectionString)
{
}
public Table<MatchItem> Matches
{
get
{
return this.GetTable<MatchItem>();

using (MatchDataContext Mchdb = new MatchDataContext(connectionString))
{
if (Mchdb.DatabaseExists())
{
Mchdb.DeleteDatabase();
}
}
}
}
I have the error The specified table does not exist[Match].
Added here is where I download
public IList<MatchItem> ParseXML(XmlReader reader)
{
//List<string> save = new List<string>();
List<MatchItem> MatchList= new List<MatchItem>();
XElement matchData;
matchData = XElement.Load(reader);
StringBuilder output = new StringBuilder();
int count = 0;
var matches = from item
in matchData.Elements("match")
select item;
foreach (XElement eachmatch in matches)
{
MatchItem mch = new MatchItem();
string Time = ((eachmatch.Element("pubdate").Value).ToString());
mch.EventName = ((eachmatch.Element("event").Value).ToString());
mch.MatchNumber = ((eachmatch.Element("mch").Value).ToString() + (eachmatch.Element("typ").Value).ToString());
string[] RT = { eachmatch.Element("red1").Value.ToString(), eachmatch.Element("red2").Value.ToString(), eachmatch.Element("red3").Value.ToString() };
string[] BT = { eachmatch.Element("blue1").Value.ToString(), eachmatch.Element("blue2").Value.ToString(), eachmatch.Element("blue3").Value.ToString() };
string RF = ((eachmatch.Element("rfin").Value).ToString());
string BF = ((eachmatch.Element("bfin").Value).ToString());
// Time = Time.Substring(0, (Time.IndexOf("+") - 1));
mch.Time = DateTime.Parse(Time);
mch.RedTeams = RT;
mch.BlueTeams = BT;
mch.RedFinal = int.Parse(RF);
mch.BlueFinal= int.Parse(BF);
mch.MatchID = count;
count += 1;
MatchList.Add(mch);
}
return MatchList;
}
This is where I call this method
void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
initializeDB();
if (e.Error == null)
{
XmlReader reader = XmlReader.Create(new StringReader(e.Result));
DownloadInfo di = new DownloadInfo();
IList <MatchItem>data= di.ParseXML(reader);
outputer(data);
addData(data.ToList<MatchItem>());
}
else
{
IList<MatchItem> data = getTeamData(strMyTeam);
outputer(data);
}
}
I ended up removing the DatabaseManager class and putting the functions in the main code
Then I output them to the screen here
public void outputer(IList<MatchItem> mch)
{
for (int i = 0; i < mch.Count; i++)
{
Score sc = new Score();
sc.Width = lsbData.Width;
sc.Height = sc.Height;
sc.Time = mch[i].Time.ToString();
sc.Event = mch[i].EventName;
sc.RT = mch[i].RedTeams[0] + " " + mch[i].RedTeams[1] + " " + mch[i].RedTeams[2];
sc.BT = mch[i].BlueTeams[0] + " " + mch[i].BlueTeams[1] + " " + mch[i].BlueTeams[2];
sc.RF = mch[i].RedFinal.ToString();
sc.BF = mch[i].BlueFinal.ToString();
lsbData.Items.Add(sc);
}
}
*note:score is a custom control that works(and worked) before the database code *

I don't see where you actually create a Match Object.
if you have you need to include that code in the question as well. and if you haven't, that would explain why it doesn't exist.
Addition
in order to add Match Objects to a list you will have to create the objects first then add them to the list, I don't think you can create the whole list of objects before creating each individual object.
more Additional Information
the object still needs to be created before you can add items to it. that is what the error is telling you. you don't have the object to insert data into.
Match Table1 = new Match();
this creates a new Match object which allows you to access the pieces of the object and insert data into the object like this
Table1.MatchNumber = 42
you can't add to something to a memory location until you set aside that memory location for that specific person and give it a name.
when you create that class you can add functions and all sorts of fun stuff to it, but you can't use any of it until you have created a Match Object.
you can't add something to a list that doesn't exist, you have to create the Match Object first, then add it to the list
