Convert List<string> to List<object> in C#

I have a list of string that looks something like this:
var rawData = new List<string>(){ "EUR/USD;123" , "EUR/GBP;321", "BTC/USD;2321"};
I have the following structure:
public class Data
{
public string instrument { get; set; }
public string positions { get; set; }
}
My goal is to have a list of the string data, splited on the ';' char and converted to a list of objects.
var processedData = new List<Data>();
// processedData[0] ( instrument = EUR/USD, positions = 123 )
// processedData[1] ( instrument = EUR/GBP, positions = 321)
// processedData[2] ( instrument = BTC/USD, positions = 2321)
Do you have any idea how can I do this ?

You can try Linq and query rawData:
var processedData = rawData
.Select(item => item.Split(';'))
.Select(items => new Data() {
instrument = items[0],
positions = items[1]
})
.ToList();

foreach(var rawString in rawData){
var split = rawString.Split(";");
processedData.Add(new Data(){
instruments = split[0],
positions = split[1]
});
}

You can try this code below
private static void TestFunc()
{
var rawData = new List<string>() { "EUR/USD;123", "EUR/GBP;321", "BTC/USD;2321" };
var processedData = new List<Data1>();
foreach (var item in rawData)
{
var ins = item.Split(";")[0];
var pos = item.Split(";")[1];
processedData.Add(new Data1(ins, pos));
}
}

you can use linq
void Main()
{
var rawData = new List<string>() { "EUR/USD;123", "EUR/GBP;321", "BTC/USD;2321" };
rawData.Select(s =>
new Data() {instrument= s.Split(";")[0],positions = (s.Split(";").Count() > 1) ? s.Split(";")[1] : null})
.ToList().Dump();
}
public class Data
{
public string instrument { get; set; }
public string positions { get; set; }
}

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!!

Parsing txt file to List

I have a txt file that want to store into a array. I'm running into a problem parsing when I have additional items on single line, as the pipe(|) would indicate another item to be stored.
Inv # Date term qty description price Tax
3221409:2017/01/12:215|10:WD2002:2TB Hard Drive:121.66:N|20:KG240S:240GB SSD:125.10:N|20:KG120S:120GB SSD:78.75:N
I'm trying to first try to open the file and show each element to the console. getting index outside the bounds of the array. The file doesn't have headers I provided them for information.
//this object lets you read from a file.
StreamReader streamReader = null;
string lineData;
string[] lineElements;
if (File.Exists(path))
{
Console.WriteLine("Woohoo file found");
try
{
int invoice;
String invoicedate;
int term;
int qty;
string description;
Boolean tax;
streamReader = new StreamReader(path);
while (streamReader.Peek() > 0)
{
lineData = streamReader.ReadLine();
var parts = lineData.Split('|');
lineElements = parts.First().Split(':');
invoice = int.Parse(lineElements[0]);
invoicedate = (lineElements[1]);
term = int.Parse(lineElements[2]);
qty = int.Parse(lineElements[3]);
Console.WriteLine(invoice);
Console.WriteLine(invoicedate);
Console.WriteLine(term);
Console.WriteLine(qty);
}

First define a structure that can hold the informations
public class InventoryData
{
public string Inv { get; set; }
public DateTime Date { get; set; }
public string Term { get; set; }
public IList<InventoryArticle> Articles { get; set; }
}
public class InventoryArticle
{
public int Quantity { get; set; }
public string Whatever { get; set; }
public string Description { get; set; }
public decimal Price { get; set; }
public bool Tax { get; set; }
}
then two methods, that will parse a single line into the structure
static InventoryData ParseInventoryData( string data )
{
var parts = data.Split( '|' );
var headparts = parts.First().Split( ':' );
var result = new InventoryData
{
Inv = headparts[0],
Date = DateTime.ParseExact( headparts[1], "yyyy/MM/dd", System.Globalization.CultureInfo.InvariantCulture ),
Term = headparts[2],
Articles = parts.Skip( 1 ).Select( part => ParseInventoryArticle( part ) ).ToList(),
};
return result;
}
static InventoryArticle ParseInventoryArticle( string data )
{
var parts = data.Split( ':' );
var result = new InventoryArticle
{
Quantity = int.Parse( parts[0] ),
Whatever = parts[1],
Description = parts[2],
Price = decimal.Parse( parts[3], System.Globalization.CultureInfo.InvariantCulture ),
Tax = parts[4] == "Y",
};
return result;
}
and finally how to parse the content of a file
string[] content = {
"Inv # Date term qty description price Tax",
"3221409:2017/01/12:215|10:WD2002:2TB Hard Drive:121.66:N|20:KG240S:240GB SSD:125.10:N|20:KG120S:120GB SSD:78.75:N" };
var data = content
// skip the header row
.Skip( 1 )
// parse the content
.Select( row => ParseInventoryData( row ) )
.ToList();

Select the Object with linq that best fit the Query strings

I have a situation where I am trying to link two different data source together. see the code below:
static void Main(string[] args)
{
string url = System.Net.WebUtility.UrlDecode("yql");
HttpClient cl = new HttpClient();
var response = cl.GetStringAsync(url).Result;
JObject json = JObject.Parse(response);
var ids = from p in json["p"]
from span in p["span"]
where (string)span["content"] == "01/19/2017"
select (string)span["genre"];
}
this is what the JSON looks likeenter code here
please note this JSON is a little different from what you will get from yql as I shorten it removing bits I don't need. this is the
link to the full JSON - https://query.yahooapis.com/v1/public/yql?q=SELECT%20*%20FROM%20html%20WHERE%20url%3D%22http%3A%2F%2Fthemoviedb.org%2Fsearch%2Fmovie%3Fquery%3Dsplit%22%20%20AND%20xpath%3D'%2F%2Fdiv%5B%40class%3D%22info%22%5D'&format=json&callback=
I want to be able to query the JSON and select the object that best match this:
string year = "2017";
string genre = "Drama, Thriller, Action";
string title = "split"
or
public class Movie{
public string year {get; set;}
public string title {get; set;}
public Genre genre{get; set;}
}
then
List<Movie> _movie = new List<Movie>()
_movie.add(new Movie{year = 2017, title=split, genre[]=Thriller, Drama, Action})
from the query object and the JSON that from yql... the result should be split 01/19/2017

public class Movie
{
public string Year { get; set; }
public string Title { get; set; }
public string[] Genre { get; set; }
}
class Program
{
static void Main(string[] args)
{
string url = System.Net.WebUtility.UrlDecode("https://query.yahooapis.com/v1/public/yql?q=SELECT%20*%20FROM%20html%20WHERE%20url%3D%22http%3A%2F%2Fthemoviedb.org%2Fsearch%2Fmovie%3Fquery%3Dsplit%22%20%20AND%20xpath%3D%27%2F%2Fdiv%5B%40class%3D%22info%22%5D%27&format=json&callback=");
HttpClient cl = new HttpClient();
var response = cl.GetStringAsync(url).Result;
JObject json = JObject.Parse(response);
var movies = new List<Movie>();
foreach (var pchild in json["query"]["results"]["div"])
{
// title
var title = pchild["p"][0]["a"]["title"];
var titleStr = title != null ? title.Value<string>() : string.Empty;
// year
var releaseDate = pchild["p"][1]["span"][0]["content"];
string releaseYear = string.Empty;
DateTime temp;
if (releaseDate != null
&& DateTime.TryParse(releaseDate.Value<string>(), System.Globalization.CultureInfo.InvariantCulture, DateTimeStyles.None, out temp))
{
releaseYear = temp.Year.ToString();
}
// genres
var genre = pchild["p"][1]["span"][1]["content"];
var genreArr = genre != null
? genre.Value<string>()
.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries)
.Select(st => st.Trim())
.ToArray()
: new string[0];
movies.Add(
new Movie
{
Title = titleStr,
Year = releaseYear,
Genre = genreArr
});
}
// searching for the best match
string titleFilter = "Split";
string yearFilter = "2017";
var genreFilter = new string[] { "Drama", "Thriller", "Action" };
var bestMatches = movies
.OrderByDescending(m => m.Title == titleFilter)
.ThenByDescending(m => m.Year == yearFilter)
.ThenByDescending(m => m.Genre.Intersect(genreFilter).Count());
// the best match
var bestMatch = bestMatches.First();
Console.WriteLine(bestMatch.Title);
Console.WriteLine(bestMatch.Year);
Console.WriteLine(string.Join(",", bestMatch.Genre));
// all the movies already ordered
//foreach (var movie in bestMatches)
//{
// Console.WriteLine(movie.Title);
// Console.WriteLine(string.Join(",", movie.Genre));
// Console.WriteLine(movie.Year);
// Console.WriteLine();
//}
Console.ReadLine();
}
Input:
string titleFilter = "Split";
string yearFilter = "2017";
var genreFilter = new string[] { "Drama", "Thriller", "Action" };
Best match:
Split
2017
Drama,Horror,Thriller
Note that you may have several movies with the same matches.
Input:
string titleFilter = "Split";
string yearFilter = "2016";
var genreFilter = new string[] { "Drama", "Thriller", "Action" };
Best matches (you can uncomment the last part of code to see all the movies ordered):
Split
Fantasy,Drama
2016
Split
Drama
2016

C# How do I create an array/matrix that stores the data?

My file looks like this:
hello,1,2,up
goodbye,0,4,down
...
I have WordToFind which will have the first word from my file, but I want it to have both the words 'hello' and 'goodbye'.
Same for X1Coordinate, I want it to have '1' and '0', but as integers.
So how can I modify my code to do that?
I'm a beginner and I tryed to figure it out for over 3 hours and still didn't manage, so I'm sorry if it's a really basic question.
for (int m = 0; m < Words; m++)
{
string LinesInFile = reader.ReadLine();
string[] WordsWithSpecifics = LinesInFile.Split(',');
string WordToFind = WordsWithSpecifics[0];
int X1Coordinate = int.Parse(WordsWithSpecifics[1]);
int Y1Coordinate = int.Parse(WordsWithSpecifics[2]);
string WordDirection = WordsWithSpecifics[3];

Now I get what you need. Below code will do what you require:
var WordToFind = new List<string>();
var X1Coordinate = new List<int>();
var Y1Coordinate = new List<int>();
var WordDirection = new List<string>();
while((LinesInFile = reader.ReadLine()) != null)
{
string[] WordsWithSpecifics = LinesInFile.Split(',');
WordToFind.Add(WordsWithSpecifics[0]);
X1Coordinate.Add(int.Parse(WordsWithSpecifics[1]));
Y1Coordinate.Add(int.Parse(WordsWithSpecifics[2]));
WordDirection.Add(WordsWithSpecifics[3]);
}
But I personally recommend using a class for storing structured data like this:
class MyDataType
{
public string Word { get; set; }
public int X1 { get; set; }
public int Y1 { get; set; }
public string Direction { get; set; }
}
Then use it like this:
var myData = new List<MyDataType>()
while((LinesInFile = reader.ReadLine()) != null)
{
string[] WordsWithSpecifics = LinesInFile.Split(',');
myData.Add(new MyDataType(){
Word = WordsWithSpecifics[0],
X1 = int.Parse(WordsWithSpecifics[1]),
Y1 = int.Parse(WordsWithSpecifics[2]),
Direction = WordsWithSpecifics[3]
};
}
