How to retrieve multiple spaces from a string

I have this method:
public static string ReplaceVarReferences(string input,char open, char close)
{
string inner = "";
for (int i = 0; i < input.Length; i++)
{
if (input[i] == open)
{
i++;
string varInner = "";
while (input[i] != close)
{
varInner += input[i];
i++;
}
inner += GetVariable(varInner);
}
else
{
inner += input[i];
}
}
return inner;
}
and this memory allocation and retrieval methods:
public static Dictionary<string, string> memory = new Dictionary<string, string>();
public static string GetVariable(string key)
{
if (memory.ContainsKey(key))
{
return memory[key];
}
else
{
return key;
}
}
public static void SetVariable(string key, string value)
{
if (memory.ContainsKey(key))
{
memory[key] = value;
}
else
{
memory.Add(key, value);
}
}
I want to to return a string with the 'ReplaceVarReferences' method and return a string with multiple spaces like this:
this code is from my interpreter and not real code.
var a = hello world;
print(variable a = {a})
the 'ReplaceVarReferences' method should be able to return this with multiple spaces:
"variable a = hello world"
but instead, it returns:
"variable a = hello world"
how can I fix this?

Ok so I looked at the wrong place I have another method that had the problem:
public static string GetNested(string Open, string Close, List<string> t, ref int i)
{
string inner = "";
int nested = 0;
while (true)
{
if (i < t.Count - 1)
{
i++;
if (string.IsNullOrWhiteSpace(t[i]))
{
for (int x = 0; x < t[i].Length; x++)
{
inner += " ";
}
}
else if (t[i] == Close)
{
nested--;
if (nested > 0)
{
inner += t[i];
}
}
else if (t[i] == Open)
{
if (nested > 0)
{
inner += t[i];
}
nested++;
}
else
{
inner += t[i];
}
if (nested == 0)
{
break;
}
}
}
return inner;
}
i did not include:
if (string.IsNullOrWhiteSpace(t[i]))
{
for (int x = 0; x < t[i].Length; x++)
{
inner += " ";
}
}
and it resulted in the spaces being dumped when retrieving the nested string.

How do I get out of this loop?
I wrote a program that checks to see if corresponding places in the numbers are the same total. The console output should be true or false. I wrote that, and then added the top part that interacts with the user, and now I get stuck in a loop. How do I get out of it?
using System;
namespace DeliverablePart1
{
class DeliverablePart1
{
static void Main(string[] args)
{
string gameAnswer;
bool repeat1 = true, repeat2 = true;
while (repeat1 == true)
{
repeat2 = true;
Console.WriteLine("Would you like to compare 2 numbers to see if their corresponding place is same total?");
gameAnswer = Console.ReadLine();
while (repeat2 == true)
{
if (gameAnswer == "yes" || gameAnswer == "yes" || gameAnswer == "YES")
{
Console.WriteLine("Please enter a three digit whole number");
string firstValue = Console.ReadLine();
int firstNumber = ValidInteger(firstValue);
Console.WriteLine("Please enter a second three digit whole number");
string secondValue = Console.ReadLine();
int secondNumber = ValidInteger(secondValue);
repeat1 = false;
repeat2 = false;
}
else if (gameAnswer == "no" || gameAnswer == "No" || gameAnswer == "NO")
{
Console.WriteLine("Okay, exiting now");
repeat1 = false;
repeat2 = false;
}
else
{
Console.WriteLine("I do not understnad what you have said");
repeat2 = false;
}
void Add(int firstNumber, int secondNumber)
{
int length1 = firstNumber.ToString().Length;
int length2 = secondNumber.ToString().Length;
string userInput;
if (length1 == length2)
{
string Answer = Convert.ToString(Compare(firstNumber, secondNumber, length1));
}
else
{
userInput = "invalid user input - Check number of digits next time.";
Console.WriteLine(userInput);
Console.ReadKey();
}
Console.ReadKey();
}
int ValidInteger(string digit1)
{
int value = 0;
string notInt = "This is not an integer.";
{
bool successfullyParsed = int.TryParse(digit1, out value);
if (successfullyParsed)
{
int firstNumber = Convert.ToInt32(value);
return value;
}
else
{
Console.WriteLine(notInt);
Console.ReadKey();
Environment.Exit(0);
return value;
}
}
}
string Compare(int a, int b, int c)
{
int lastDigitA;
int lastDigitB;
lastDigitA = (a % 10);
lastDigitB = (b % 10);
int sumStatic = lastDigitA + lastDigitB;
do
{
lastDigitA = (a % 10);
lastDigitB = (b % 10);
a = a / 10;
b = b / 10;
c--;
int sumCompare = lastDigitA + lastDigitB;
if (sumCompare != sumStatic)
{
Console.WriteLine("False");
return "False";
}
}
while (c != 0);
Console.WriteLine("True");
return "True";
}
}
}
}
}
}

From my understanding, it looks like you want the user to enter in three ints (with some input validation), and put the three ints through the Compare() function. If the function returns true, then say "True" to the console, and if it's false then say "False" to the console. If that's the case, I refactored your code into this (and it doesn't get stuck in a loop):
using System;
namespace DeliverablePart1
{
internal class DeliverablePart1
{
private static void Main(string[] args)
{
Console.WriteLine("Would you like to compare 2 numbers to see if their corresponding place is same total?");
var shouldContinue = Console.ReadLine();
if (shouldContinue != null && shouldContinue.Equals("yes", StringComparison.CurrentCultureIgnoreCase))
{
var firstNum = GetIntFromUser("Please enter a three digit whole number");
var secondNum = GetIntFromUser("Please enter a three digit whole number");
var thirdNum = GetIntFromUser("Please enter a three digit whole number");
Console.WriteLine(Compare(firstNum, secondNum, thirdNum) ? "True" : "False");
}
else
{
Console.WriteLine("Exiting");
}
// waits for the user to press a key to exit the app, so that they can see their result
Console.ReadKey();
}
/// <summary>
/// Makes the user enter in a three digit number, and exits if they say "no"
/// </summary>
/// <param name="msg">The message prompt to ask for the integer</param>
/// <returns>System.Int32., or will exit</returns>
public static int GetIntFromUser(string msg)
{
while (true)
{
Console.WriteLine(msg);
var valFromUser = Console.ReadLine()?.Trim();
if (valFromUser != null)
{
int result;
if (int.TryParse(valFromUser.Trim(), out result) && valFromUser.Length == 3)
{
return result;
}
if (valFromUser.Equals("no", StringComparison.CurrentCultureIgnoreCase))
{
Console.WriteLine("Exiting.");
Environment.Exit(0);
}
}
Console.WriteLine("Hmm, that's not a three digit number. Try again.");
}
}
public static bool Compare(int a, int b, int c)
{
var lastDigitA = a % 10;
var lastDigitB = b % 10;
var sumStatic = lastDigitA + lastDigitB;
do
{
lastDigitA = a % 10;
lastDigitB = b % 10;
a = a / 10;
b = b / 10;
c--;
var sumCompare = lastDigitA + lastDigitB;
if (sumCompare != sumStatic)
{
return false;
}
} while (c != 0);
return true;
}
}

Pick random word from list?

I´m having trouble picking a random word from a list in another file.
Actually I can´t even get it to choose any word. I´m not sure how to connect the 2 files so to say.
Hoping someone can help out, I´m a beginner so please explain as easy as possible:)
I have 2 files, one is called program.cs and the other is called WordList.cs
I´m gonna paste all my code but first the little snip that I´m having problem with. I just can´t figure out how to write the code correct.
Here is the little part which is called Pick word:
//PICK WORD
static string pickWord()
{
string returnword = "";
TextReader file = new StreamReader(words);
string fileLine = file.ReadLine();
Random randomGen = new Random();
returnword = words[randomGen.Next(0, words.Count - 1)];
return returnword;
}
And here is all the code in Program.cs
using System;

}
Wordlist.cs
using System;
using System.Collections.Generic;
public class WordList : List<string>
{
}

Here is the very simple solution:
Populate your list just one time, or when ever you add any word, call this method. Code:
private void PopulateTheWordList()
{
Console.Write("\n\tAdd a word\n\n");
WordList.Add(Console.ReadLine());
}
Now just call this method to get random words:
private string PickWord()
{
Random ran = new Random();
return WordList[ran.Next(0, WordList.Count)];
}
If you need to create List of words in another class, then use keyword static:
static List<string> WordList = new List<string>();
Now you can call it by just writing the class name, like YourClassName.WordList

Try creating a Static Class and add a method for returning your List, you will then be able to access your wordlist.
example:
static class WordList
{
static List<string> words = new List<string>();
public static void ListOfWords()
{
words.Add("test"); // Contains: test
words.Add("dog"); // Contains: test, dog
words.Insert(1, "shit"); // Contains: test, shit, dog
words.Sort();
foreach (string word in words) // Display for verification
{
Console.WriteLine(word);
}
}
public static List<string> GetWords()
{
return words;
}
public static void AddWord(string value)
{
words.Add(value);
}
}
You would then change your switch statement to look something like this.
switch (MenuChoice)
{
case 1:
Console.Write("\n\tAdd a word\n\n");
var insert = Console.ReadLine();
WordList.AddWord(insert);
Console.Write("\n\tList of words\n\n");
WordList.ListOfWords();
break;
case 2:
Console.Write("\n\tList of words\n\n");
WordList.ListOfWords();
break;
....
and your pickWord Method would look like this:
static string pickWord()
{
string returnword = "";
Random randomGen = new Random();
returnword = WordList.GetWords()[randomGen.Next(0, WordList.GetWords().Count() - 1)];
return returnword;
}
I modified your Wordlist class so that it can use a file to maintain your Words between uses of your program, just incase that is what was being asked of you.
static class WordList
{
static string filePath = #"C:\temp\Word.txt";
static List<string> words = new List<string>();
private static void CheckFile()
{
//Makes sure our base words are saved to the file
if (!File.Exists(#"C:\temp\Word.txt"))
{
using (TextWriter writer = new StreamWriter(filePath))
{
writer.WriteLine("test");
writer.WriteLine("dog");
writer.WriteLine("shit");
}
}
}
public static void ListOfWords()
{
CheckFile();
words.Clear();
using (TextReader file = new StreamReader(filePath))
{
char[] delineators = new char[] { '\r', '\n' };
string[] tempWords = file.ReadToEnd().Split(delineators, StringSplitOptions.RemoveEmptyEntries);
foreach (string line in tempWords)
{
words.Add(line);
}
}
foreach (string word in words) // Display for verification
{
Console.WriteLine(word);
}
}
public static List<string> GetWords()
{
return words;
}
public static void AddWord(string value)
{
CheckFile();
using (TextWriter writer = new StreamWriter(filePath,true ))
{
writer.WriteLine(value);
}
}
}

c# text difference

I have two words:
Source: John
ConvertTo: Jack
and I want to show the effect of convert all letters from "Source" at the same time to the "ConvertTo" word. I already create a program to accomplish that but processing one letter at a time, to show the effect I use Threads, the thing is that to process all letters at the same time I suppose I need one thread per letter, and every thread will call the same function that process the letter, and I use global variables.
Here is the code (works only for texts with same lenght):
private void button1_Click(object sender, EventArgs e)
{
lblResult.Text = "";
lblResult2.Text = "";
ThreadPool.QueueUserWorkItem(new WaitCallback(Process));
}
int movement = 0;
string CumulateText;
private void Process(object stateinfo)
{
int value;
int operation; //0->[+] 1->[-]
CumulateText = "";
for (int i = 0; i <= textBox1.Text.Length - 1; i++)
{
if (textBox1.Text[i] != ' ')
{
value = (char)textBox1.Text[i] - (char)textBox2.Text[i];
if (value >= 0)
operation = 1;
else
operation = 0;
for (int ii = 0; ii <= Math.Abs(value); ii++)
{
if (operation == 1)
movement = (char)textBox1.Text[i] - ii;
else
movement = (char)textBox1.Text[i] + ii;
this.Invoke(new EventHandler(ShowMovement));
System.Threading.Thread.Sleep(10);
}
}
CumulateText += textBox2.Text[i].ToString();
}
}
private void ShowMovement(object sender, EventArgs e)
{
lblResult.Text = CumulateText + Convert.ToString((char)movement);
}
I hope I made myself understood.
please any advise to accomplish that.
thanks
To clarify more what I want to accomplish here is an example:
Source: John
ConvertTo: Jack
J - same J
o - decrease till a (o, n, m, ..., a)
h - decrease till c (h, g, f, ..., c)
n - decrease till k (n, m, l, k)

I once had to do something similar for a small little project I was working on for fun.
I do not see why you would need to create a thread for each letter to create a transition between two words unless I'm not understanding what you are pretending to do correctly.
Check and study the following code, see if its any help:

{
static void Main()
{
TextTranstition transition = new TextTranstition();
transition.TransitionFinished += TransitionTicked;
transition.TransitionTicked += TransitionTicked;
transition.StartTransition("AmazingWordTransition", "MyNewWordAppearing", 100);
Thread.CurrentThread.Join();
Console.ReadKey();
}
public static void TransitionTicked(object sender, TranstitionEventArgs e)
{
Console.Clear();
Console.Write(e.TransitionText);
}
}

convert Javascript function to c#

I want to convert following javascript function to c#
can anyone help?
function parseCoordinate(coordinate,type,format,spaced) {
coordinate = coordinate.toString();
coordinate = coordinate.replace(/(^\s+|\s+$)/g,''); // remove white space
var neg = 0; if (coordinate.match(/(^-|[WS])/i)) { neg = 1; }
if (coordinate.match(/[EW]/i) && !type) { type = 'lon'; }
if (coordinate.match(/[NS]/i) && !type) { type = 'lat'; }
coordinate = coordinate.replace(/[NESW\-]/gi,' ');
if (!coordinate.match(/[0-9]/i)) {
return '';
}
parts = coordinate.match(/([0-9\.\-]+)[^0-9\.]*([0-9\.]+)?[^0-9\.]*([0-9\.]+)?/);
if (!parts || parts[1] == null) {
return '';
} else {
n = parseFloat(parts[1]);
if (parts[2]) { n = n + parseFloat(parts[2])/60; }
if (parts[3]) { n = n + parseFloat(parts[3])/3600; }
if (neg && n >= 0) { n = 0 - n; }
if (format == 'dmm') {
if (spaced) {
n = Degrees_to_DMM(n,type,' ');
} else {
n = Degrees_to_DMM(n,type);
}
} else if (format == 'dms') {
if (spaced) {
n = Degrees_to_DMS(n,type,' ');
} else {
n = Degrees_to_DMS(n,type,'');
}
} else {
n = Math.round(10000000 * n) / 10000000;
if (n == Math.floor(n)) { n = n + '.0'; }
}
return comma2point(n);
}
}

Check out Regex on MSDN or have a quick look on google for Regex C#
if (coordinate.match(/(^-|[WS])/i)) { neg = 1; }
would become:
using System.Text.RegularExpressions;
Regex myRegex = new Regex("/(^-|[WS])/i)");
if (coordinate.IsMatch(myRegex))
{
neg=1;
}
If it will always be like your above example 'N27 53.4891' then you could store it as a string. If the above latitude is in 2 parts ('N27' and 53.4891) and you need to access them seperately then you could have a custom Coordinate class, e.g.
public class coordinate
{
public string otherPart {get; set;} // N27
public float coordPart {get; set;} // 53.4891
}
You can then override the .toString() method to get 'N27 53.4891'.

Regex myPattern =new Regex("/(^-|[WS])/i)");
if(myPattern.isMatch(coordinate))
{ neg = 1; }
see if this works
