public string[] CcEmails { get; set; }
Mail.cs
EDTO.CcEmails = dr["rsh_ccmail"].ToString().Split(';');
here i got two strings eg. xxxx#gmail.com ; yyy#gmail.com
MailProcess.cs
dataRPT1=get data from sql
EDTO.CcEmails = new string[dataRPT1.Rows.Count];
for (int i = 0; i < dataRPT1.Rows.Count; i++)
{
EDTO.CcEmails[i] = dataRPT1.Rows[i]["email_addr"].ToString();
}
Here i got list of string eg.aaa#gmail.com ......
I am try to add with existing but it add only new values..Anyone could help me..
I tend to use union, although that will remove duplicate entries. But to keep all entries you can use Concat on the array.
var emailString = "me#test.com;you#test.com";
string[] emails = emailString.Split(';');
string[] emailsFromSQL = new string[3];
emailsFromSQL[0] = "everyone#test.com";
emailsFromSQL[1] = "everyone2#test.com";
emailsFromSQL[2] = "everyone2#test.com";
//No Duplicates
var combined = emails.Union(emailsFromSQL).ToArray();
//Duplicates
var allCombined = emails.Concat(emailsFromSQL).ToArray();
Thanks
I find the easiest way of doing this is to create a list, add items to the list, then use string.Join to create the new string.
var items = new List<string>();
for (int i = 0; i < dataRPT1.Rows.Count; i++)
{
items.Add(dataRPT1.Rows[i]["email_addr"].ToString());
}
EDTO.CcEmails = string.Join(";", items);
Update after changed question:
If the type of the CcEmails is an array, the last line could be:
EDTO.CcEmails = items.ToArray();
Problem Statement
In order to run gene annotation software, I need to prepare two types of files, vcard files and coverage tables, and there has to be one-to-one match of vcard to coverage table. Since Im running 2k samples, its hard to identify which file is not one-to-one match. I know that both files have unique identifier numbers, hence, if both folders have files that have same unique numbers, i treat that as "same" file
I made a program that compares two folders and reports unique entries in each folder. To do so, I made two list that contains unique file names to each directory.
I want to format the report file (tab delimited .txt file) such that it looks something like below:
Unique in fdr1 Unique in fdr2
file x file a
file y file b
file z file c
I find this difficult to do because I have to iterate twice (since I have two lists), but there is no way of going back to the previous line in StreamWriter as far as I know. Basically, once I iterate through the first list and fill the first column, how can I fill the second column with the second list?
Can someone help me out with this?
Thanks
If design of the code has to change (i.e. one list instead of two), please let me know
As requested by some user, this is how I was going to do (not working version)
// Write report
using (StreamWriter sw = new StreamWriter(dest_txt.Text + #"\" + "Report.txt"))
{
// Write headers
sw.WriteLine("Unique Entries in Folder1" + "\t" + "Unique Entries in Folder2");
// Write unique entries in fdr1
foreach(string file in fdr1FileList)
{
sw.WriteLine(file + "\t");
}
// Write unique entries in fdr2
foreach (string file in fdr2FileList)
{
sw.WriteLine(file + "\t");
}
sw.Dispose();
}
As requested for my approach for finding unique entries, here's my code snippet
Dictionary<int, bool> fdr1Dict = new Dictionary<int, bool>();
Dictionary<int, bool> fdr2Dict = new Dictionary<int, bool>();
List<string> fdr1FileList = new List<string>();
List<string> fdr2FileList = new List<string>();
string fdr1Path = folder1_txt.Text;
string fdr2Path = folder2_txt.Text;
// File names in the specified directory; path not included
string[] fdr1FileNames = Directory.GetFiles(fdr1Path).Select(Path.GetFileName).ToArray();
string[] fdr2FileNames = Directory.GetFiles(fdr2Path).Select(Path.GetFileName).ToArray();
// Iterate through the first directory, and add GL number to dictionary
for(int i = 0; i < fdr1FileNames.Length; i++)
{
// Grabs only the number from the file name
string number = Regex.Match(fdr1FileNames[i], #"\d+").ToString();
int glNumber;
// Make sure it is a number
if(Int32.TryParse(number, out glNumber))
{
fdr1Dict[glNumber] = true;
}
// If number not present, raise exception
else
{
throw new Exception(String.Format("GL Number not found in: {0}", fdr1FileNames[i]));
}
}
// Iterate through the second directory, and add GL number to dictionary
for (int i = 0; i < fdr2FileNames.Length; i++)
{
// Grabs only the number from the file name
string number = Regex.Match(fdr2FileNames[i], #"\d+").ToString();
int glNumber;
// Make sure it is a number
if (Int32.TryParse(number, out glNumber))
{
fdr2Dict[glNumber] = true;
}
// If number not present, raise exception
else
{
throw new Exception(String.Format("GL Number not found in: {0}", fdr2FileNames[i]));
}
}
// Iterate through the first directory, and find files that are unique to it
for (int i = 0; i < fdr1FileNames.Length; i++)
{
int glNumber = Int32.Parse(Regex.Match(fdr1FileNames[i], #"\d+").Value);
// If same file is not present in the second folder add to the list
if(!fdr2Dict[glNumber])
{
fdr1FileList.Add(fdr1FileNames[i]);
}
}
// Iterate through the second directory, and find files that are unique to it
for (int i = 0; i < fdr2FileNames.Length; i++)
{
int glNumber = Int32.Parse(Regex.Match(fdr2FileNames[i], #"\d+").Value);
// If same file is not present in the first folder add to the list
if (!fdr1Dict[glNumber])
{
fdr2FileList.Add(fdr2FileNames[i]);
}
I am a quite confident that this will work as I've tested it:
static void Main(string[] args)
{
var firstDir = #"Path1";
var secondDir = #"Path2";
var firstDirFiles = System.IO.Directory.GetFiles(firstDir);
var secondDirFiles = System.IO.Directory.GetFiles(secondDir);
print2Dirs(firstDirFiles, secondDirFiles);
}
private static void print2Dirs(string[] firstDirFile, string[] secondDirFiles)
{
var maxIndex = Math.Max(firstDirFile.Length, secondDirFiles.Length);
using (StreamWriter streamWriter = new StreamWriter("result.txt"))
{
streamWriter.WriteLine(string.Format("{0,-150}{1,-150}", "Unique in fdr1", "Unique in fdr2"));
for (int i = 0; i < maxIndex; i++)
{
streamWriter.WriteLine(string.Format("{0,-150}{1,-150}",
firstDirFile.Length > i ? firstDirFile[i] : string.Empty,
secondDirFiles.Length > i ? secondDirFiles[i] : string.Empty));
}
}
}
It's a quite simple code but if you need help understanding it just let me know :)
I would construct each line at a time. Something like this:
int row = 0;
string[] fdr1FileList = new string[0];
string[] fdr2FileList = new string[0];
while (row < fdr1FileList.Length || row < fdr2FileList.Length)
{
string rowText = "";
rowText += (row >= fdr1FileList.Length ? "\t" : fdr1FileList[row] + "\t");
rowText += (row >= fdr2FileList.Length ? "\t" : fdr2FileList[row]);
row++;
}
Try something like this:
static void Main(string[] args)
{
Dictionary<int, string> fdr1Dict = FilesToDictionary(Directory.GetFiles("path1"));
Dictionary<int, string> fdr2Dict = FilesToDictionary(Directory.GetFiles("path2"));
var unique_f1 = fdr1Dict.Where(f1 => !fdr2Dict.ContainsKey(f1.Key)).ToArray();
var unique_f2 = fdr2Dict.Where(f2 => !fdr1Dict.ContainsKey(f2.Key)).ToArray();
int f1_size = unique_f1.Length;
int f2_size = unique_f2.Length;
int list_length = 0;
if (f1_size > f2_size)
{
list_length = f1_size;
Array.Resize(ref unique_f2, list_length);
}
else
{
list_length = f2_size;
Array.Resize(ref unique_f1, list_length);
}
using (StreamWriter writer = new StreamWriter("output.txt"))
{
writer.WriteLine(string.Format("{0,-30}{1,-30}", "Unique in fdr1", "Unique in fdr2"));
for (int i = 0; i < list_length; i++)
{
writer.WriteLine(string.Format("{0,-30}{1,-30}", unique_f1[i].Value, unique_f2[i].Value));
}
}
}
static Dictionary<int, string> FilesToDictionary(string[] filenames)
{
Dictionary<int, string> dict = new Dictionary<int, string>();
for (int i = 0; i < filenames.Length; i++)
{
int glNumber;
string filename = Path.GetFileName(filenames[i]);
string number = Regex.Match(filename, #"\d+").ToString();
if (int.TryParse(number, out glNumber))
dict.Add(glNumber, filename);
}
return dict;
}
Good day I have some problem regarding selecting a random string from my string array I am currently developing a guessing word game.
this is my string array:
string[] movie = {"deadpool", "batmanvssuperman", "findingdory", "titanic", "suicidesquad", "lordoftherings", "harrypotter", "jurassicpark", "hungergames", "despicableme" };
while this is the process in selecting a random string to my array, what should i do next, because I want to select the string not repeated.
e.g
when the program starts it will select a string then when i select random string again i want to not select the previous word that i've already selected previously.
string word = movie[r.Next(0, movie.Length)].ToUpper();
Thank you for response! Have a nice day.
Well, simply convert your array to list and shuffle it in random order :
var rand = new Random();
string[] movies = { "deadpool", "batmanvssuperman", "findingdory", "titanic", "suicidesquad", "lordoftherings", "harrypotter", "jurassicpark", "hungergames", "despicableme" };
List<string> randomMovies = movies.ToList();
for (int i = 0; i < movies.Length / 2; i++)
{
var randNum = rand.Next(i, randomMovies.Count);
var temp = randomMovies[randNum];
randomMovies[randNum] = randomMovies[i];
randomMovies[i] = temp;
}
Then you can just take random elements by :
var randomMovie = randomMovies.First();
randomMovies.Remove(randomMovie); // either remove it or use loop to iterate through the list
I sort of like to use Queue collection here :
var moviesQueue = new Queue<string>(randomMovies);
while (moviewQueue.Count > 0)
{
Console.WriteLine(moviewQueue.Dequeue());
}
P.S.
As suggested you don't really need to delete elements from randomMovie, you can save last used index in some field and use it later;
var lastIndex = 0;
var randomMovie = randomMovies[lastIndex++];
Just loop if it's been selected. This is untested code:
private string _last;
private string GetNonRepeatedMovie()
{
string selected = "";
do
{
selected = movie[r.Next(0, movie.Length)].ToUpper();
}
while (selected == this._last);
this._last = selected;
return selected;
}
This should work to select the initial string as well when the application starts.
If you need to keep a memory, convert your list to be a class that contains the name and a field of whether it has been chosen or not.
If you go through all of them, turn this semiphor off and begin again.
class GuessingName
{
public GuessingName(string name){Name = name;}
public string Name;
public bool chosen;
}
class RandomNamePicker{
private List<GuessingName> names;
public RandomNamePicker(){
names = new List<GuessingName>();
names.Add(new GuessingName("movie"));
}
string RandomPicker(){
if(names.All(c=>c.chosen))
names.ForEach(c=>c.chosen=false);
int r1 = r.Next(0, names.Length);
while(names[r1].chosen){
r1= r.Next(0,names.Length);
}
return names[r1].Name;
}
}
I'm attempting to import a CSV file into a DataTable, however the CSV contains headers that are the same. (For example, there are multiple "Date" headers for different form sections). To fix this, I decided to create a loop that will run through the headers and replace the duplicates or unwanted entries based on their position. I've replaced my replaceWith array with dummy entries, but my actual code does have the correct size to correlate with the replace array.
string[] columnNames = null;
string[] oStreamDataValues = null;
int[] error = {0,1,2,3,4,7,8,9,10,11,15,21,34,37,57,61,65,68,69,71,75,79,82,83,85,89,93,96,97,99,103,107,110,111,113,117,121,124,125,127,128,129,130,132,182,210,212,213,214,215,216,222,226,239};
int[] replace = {14,16,17,17,20,23,24,27,28,29,31,32,44,58,59,60,62,63,64,66,67,70,72,73,74,76,77,78,80,81,84,86,87,88,90,91,92,94,95,98,100,101,102,104,105,106,108,109,112,114,115,116,118,119,120,122,123,126,134,136,138,140,142,144,146,148,150,152,154,156,158,160,162,164,166,168,170,172,174,176,178,180,184,186,187,188,190,191,192,194,195,196,198,199,200,202,203,204,206,207,208,209,236,242,243,244};
string[] replaceWith = {"Replace 1", "Replace 2", "Replace 3"};
string fix = "ignore_";
int inc = 00;
string entry = "";
while (!oStreamReader.EndOfStream)
{
string oStreamRowData = oStreamReader.ReadLine().Trim();
if (oStreamRowData.Length > 0)
{
//oStreamDataValues = Regex.Split(oStreamRowData, ",(?=(?:[^']*'[^']*')*[^']*$)");
oStreamDataValues = oStreamRowData.Split(',');
if (rowCount == 0)
{
rowCount = 1;
columnNames = oStreamDataValues;
for (int i = 0; i < columnNames.Length; i++)
{
for (int j = 0; j < error.Length; j++)
{
if (error[j] == i)
{
entry = fix + inc++;
}
}
for (int k = 0; k < replace.Length; k++)
{
if (replace[i] == i)
{
int add = 0;
entry = replaceWith[add++];
}
}
DataColumn oDataColumn = new DataColumn(entry, typeof(string));
oDataColumn.DefaultValue = string.Empty;
oDataTable.Columns.Add(oDataColumn);
}
}
}
I'm no coding expert, so my syntax/decision making isn't perfect.
However the error that I get is that A column named 'ignore_4' already belongs to this DataTable.
I assume something is incorrect in my loop logic.
I think you have overcomplicated the loops. You just need to keep an index of the current position in the array of errors and array of replaces.
string rep = "replace_"; // base string for replace fields
string fix = "ignore_"; // base string for ignore fields
// For demonstation purpose I have commented out this array. If you
// want every 'replace' column have its specific name then prepare this
// array with exactly the number of names required by the number of
// elements in the replace array
//
// string[] replaceWith = {"Replace 1", "Replace 2", "Replace 3"};
int idxErrors = 0; // Current position in the error array
int idxReplace = 0; // Current position in the replace array
int fixCounter = 1;
int repCounter = 1;
string entry = "";
for (int i = 0; i < columnNames.Length; i++)
{
// Is this the index of a column that should be ignored?
if (idxErrors < error.Length && i == error[idxErrors])
{
entry = fix + fixCounter.ToString("D2");
idxErrors++;
fixCounter++;
}
// Is this the index of a column that should have a different name??
else if (idxReplace < replace.Length && i == replace[idxReplace])
{
entry = rep + repCounter.ToString("D2");
// entry = replaceWith[repCounter];
idxReplace++;
repCounter++;
}
else
entry = columnNames[i];
// Now create the column
DataColumn oDataColumn = new DataColumn(entry, typeof(string));
oDataColumn.DefaultValue = string.Empty;
oDataTable.Columns.Add(oDataColumn);
}
In this example I have used the same pattern used for the ignored column also for the columns that need to have the name changed. If you want to give each renamed column a proper name, then you need to prepare an array with these proper names and this array should be of the same length of the replace array. Then use the idxReplace to take the correct name from the array of possible proper names.
I have a .csv with the following headers and an example line from the file.
AgentID,Profile,Avatar,In_Time,Out_Time,In_Location,Out_Location,Target_Speed(m/s),Distance_Traveled(m),Congested_Duration(s),Total_Duration(s),LOS_A_Duration(s),LOS_B_Duration(s),LOS_C_Duration(s),LOS_D_Duration(s),LOS_E_Duration(s),LOS_F_Duration(s)
2177,DefaultProfile,DarkGreen_LowPoly,08:00:00,08:00:53,East12SubwayportalActor,EWConcourseportalActor,1.39653,60.2243,5.4,52.8,26.4,23,3.4,0,0,0
I need to sort this .csv by the 4th column (In_time) by increasing time ( 08:00:00, 08:00:01) and the 6th (In_Location) by alphabetical direction (e.g. East, North, etc).
So far my code looks like this:
List<string> list = new List<string>();
using (StreamReader reader = new StreamReader("JourneyTimes.csv"))
{
string line;
while ((line = reader.ReadLine()) != null)
{
line.Split(',');
list.Add(line);
}
I read in the .csv and split it using a comma (there are no other commas so this is not a concern). I then add each line to a list. My issue is how do I sort the list on two parameters and by the headers of the .csv.
I have been looking all day at this, I am relatively new to programming, this is my first program so I apologize for my lack of knowledge.
You can use LINQ OrderBy/ThenBy:
e.g.
listOfObjects.OrderBy (c => c.LastName).ThenBy (c => c.FirstName)
But first off, you should map your CSV line to some object.
To map CSV line to object you can predefine some type or create it dynamically
from line in File.ReadLines(fileName).Skip(1) //header
let columns = line.Split(',') //really basic CSV parsing, consider removing empty entries and supporting quotes
select new
{
AgentID = columns[0],
Profile = int.Parse(columns[1]),
Avatar = float.Parse(columns[2])
//other properties
}
And be aware that like many other LINQ methods, these two use deferred execution
You are dealing with two distinct problems.
First, ordering two columns in C# can be achieved with OrderBy, ThenBy
public class SpreadsheetExample
{
public DateTime InTime { get; set; }
public string InLocation { get; set; }
public SpreadsheetExample(DateTime inTime, string inLocation)
{
InTime = inTime;
InLocation = inLocation;
}
public static List<SpreadsheetExample> LoadMockData()
{
int maxMock = 10;
Random random = new Random();
var result = new List<SpreadsheetExample>();
for (int mockCount = 0; mockCount < maxMock; mockCount++)
{
var genNumber = random.Next(1, maxMock);
var genDate = DateTime.Now.AddDays(genNumber);
result.Add(new SpreadsheetExample(genDate, "Location" + mockCount));
}
return result;
}
}
internal class Class1
{
private static void Main()
{
var mockData = SpreadsheetExample.LoadMockData();
var orderedResult = mockData.OrderBy(m => m.InTime).ThenBy(m => m.InLocation);//Order, ThenBy can be used to perform ordering of two columns
foreach (var item in orderedResult)
{
Console.WriteLine("{0} : {1}", item.InTime, item.InLocation);
}
}
}
Now you can tackle the second issue of moving data into a class from Excel. VSTO is what you are looking for. There are lots of examples online. Follow the example I posted above. Replace your custom class in place of SpreadSheetExample.
You may use a DataTable:
var lines = File.ReadAllLines("test.csv");
DataTable dt = new DataTable();
var columNames = lines[0].Split(new char[] { ',' });
for (int i = 0; i < columNames.Length; i++)
{
dt.Columns.Add(columNames[i]);
}
for (int i = 1; i < lines.Length; i++)
{
dt.Rows.Add(lines[i].Split(new char[] { ',' }));
}
var rows = dt.Rows.Cast<DataRow>();
var result = rows.OrderBy(i => i["In_time"])
.ThenBy(i => i["In_Location"]);
// sum
var sum = rows.Sum(i => Int32.Parse(i["AgentID"].ToString()));
