I am trying to assert whether two or more strings are evident. My code currently only looks for "Good". Is there a way to look for "Good" or "Bad"?
public class Test
{
public static bool FindText()
{
var conf = Driver.Instance.FindElement(By.Id("foo"));
if (conf.Text.Contains("Good"))
{
return true;
}
throw new Exception("Text not found");
}
}
I would use System.Linq and check against all elements of an array, if there could possibly be more than two valid strings.
public class Test
{
public static bool FindText()
{
var stringsToFind = new [] { "Good", "Bad" };
var conf = Driver.Instance.FindElement(By.Id("foo"));
if (stringsToFind.Any(s => conf.Text.Contains(s))
{
return true;
}
throw new Exception("Text not found");
}
}
for only two elements to check I would propably just extend the if condition with a second condition and an or.
When trying to find a string, always make the string variable to upper or lower case. Since it's case sensitive, when the text is "GoOd", you won't find a match looking for "Good"
if(conf.Text.ToUpper().Contains("GOOD")){
//do something
}
else if(conf.Text.ToUpper().Contains("BAD")){
//do something else
}
You could also put then in only one "if" statement, if you're only interested in finding out if there's any of those by using
if(conf.Text.ToUpper().Contains("GOOD") || conf.Text.ToUpper().Contains("BAD")){
//do something for both cases
}
|| is the operator for the OR operation
if (conf.Text.Contains("Good") || conf.Text.Contains("Bad"))
PD : Stop whatever you are doing and take a look to the language docs, you need to understand what are you doing.

What i want to do is to use something like this Console.Writeline($"Name {Key} - Points: {Value}");
but i dont know how to make the data from the txt into Keys and Values.
I see, you want to fill a Dictionary<string, int> with the names and points of people, right?
If yes then I would suggest never use a dictionary Keys for names, because names are the data that can be duplicate which will eventually lead your software to throw exceptions regarding that.
Make a Generic List of custom class data. Something like this:
public class UserPoint
{
public string Name { get; set; }
public int Points { get; set; }
}
Then like below you can read your text file and load the data into the Generic List.
public static void Main(string[] args)
{
var lines = System.IO.File.ReadAllLines(#"myfile.txt"); // I assume each user info is separated by a newline.
var pointsList = new List<UserPoint>();
foreach(var line in lines)
{
var splittedLine = line.Split(';');
if(splittedLine.Length < 1) continue;
var userPoint = new UserPoint { Name = splittedLine[0].Trim() };
if(splittedLine.Length > 1 && int.TryParse(splittedLine[1].Trim(), out var points)) // updated the direct conversion to safe conversion with tryparse.
{
userPoint.Points = points; // To get rid of extra parsing you can also keep Points property as string.
}
pointsList.Add(userPoint);
}
}
PS: There are multiple other ways to read the text file but I used a simple way, You can also use FileStream and StreamReader classes if you like. Read more on reading text files on these MSDN Articles.
EDIT:
I notice you want to iterate and print through the list as well, you can do in the first loop or you can write a loop again. See:
foreach(var userPoint in pointsList)
{
Console.WriteLine($"Name: {userPoint.Name}, Points: {userPoint.Points}");
}
EDIT 2:
OP has asked to sort the list in descending order based on the points value. Here is a solution for that:
pointsList = pointsList.OrderByDescending(userPoint => userPoint.Points).ToList();

I'm trying to convert emoji's like the one below to c# code so I can put the code in a TreeView node or facebook or other social engine. I tried the code for airplane and shows a little airplane in the treenode. But I use another airplace code like U+1F6E9 it just shows a little rectangle not the emoji. Please help.
string tnt = "Airplane " + char.ConvertFromUtf32(int.Parse("U+2708".Substring(2), System.Globalization.NumberStyles.HexNumber));
MyTreeView.Nodes.Add(tnt);
Here is a class you may use to implement different emoji's in your application.
public class Emoji
{
readonly int[] codes;
public Emoji(int[] codes)
{
this.codes = codes;
}
public Emoji(int code)
{
codes = new int[] { code };
}
public override string ToString()
{
if (codes == null)
return string.Empty;
var sb = new StringBuilder(codes.Length);
foreach (var code in codes)
sb.Append(Char.ConvertFromUtf32(code));
return sb.ToString();
}
}
I would use the codes from this site unicode.org
Instead of using the code it has on the site which is something like 'U+1F366' I would use '0x1F366' to specify hexadecimal notation. Hope this helps.

First of all sorry if this is a duplicate. I dont exactly know how to search for this.
I have a question about how to be able to use a saved string to change what type of method I call
MenuBar.Dock = Dockstyle.DockStyleString //DockStyleString is a string defined somewhere with either Top or Bottom
So, according to your example you seem to be using an enumerator. Enum has utilities that would 'convert' a string into the right enum value. Also you can have an utility class that does that for you.
DockstyleUtils.FromString("DockStyleString");
This would return an enum Dockstyle.DockstyleString.
So, you can use it MenuBar.Dock = DockstyleUtils.FromString("DockStyleString");
I created this method you can use...
public DockStyle ConvertDockingStyleFromString(string dockingStyle)
{
return (DockStyle)Enum.Parse(typeof(DockStyle), dockingStyle);
}
There you go.
Some of this depends on what you want to do with the string once you have it. You can use the code in #PepitoFernandez's answer to convert it to an enum. If you'd like to then use it to determine what method to call against an object, you have a few options.
The first is that if it's a known set of strings, you could use a switch statement:
switch (stringVariable) {
case "stringA": methodA(); break;
case "stringB": methodB(); break;
...
// If you get a "bad" string, you WANT to throw an exception to make
// debugging easier
default: throw new ArgumentException("Method name not recognized");
}
Obviously, you can also replace this with enum values if you do the conversion first. (That's actually not a bad idea because if you get a "bad" string you
The other option (if you want to do it dynamically at runtime) is to do the call using reflection, like this:
public class SomeClass
{
public void MethodA()
{
Console.WriteLine("MethodA");
}
}
static void Main(string[] args)
{
Type type = typeof(SomeClass);
// Obviously, you'll want to replace the hardcode with your string
MethodInfo method = type.GetMethod("MethodA");
SomeClass cls = new SomeClass();
// The second argument is the parameters; I pass null here because
// there aren't any in this case
method.Invoke(cls, null);
}

I have two function with different functionality and i want to call them based on some value. without if else or switch case block. like i have
Dictionary<string, string> intentMap = new Dictionary<string, string>();
intentMap.Add("rootIntent", "TicketbookingInformation");
intentMap.Add("rootIntent", "OrderInformation");
and i have two function
public bool BookTicket()
{
// to do
}
public bool BookOrder()
{
// to do
}
I want to switch these function if intentMap has TicketbookingInformation then call BookTicket method or if intentMap has OrderInformation then call BookOrder method.
I want to do in generic way using deleagtes so in future if I have some more use case (new method), so i can utilize the same functionlaity without modifying much.
Use another dictionary, this time of type <string, Func<bool>:
var delegateMap = new Dictionary<string, Func<bool>>()
{
{ "TicketBookingInformation", BookTicket },
{ "OrderInformation", BookOrder }
};
foreach (var intent in intentMap)
{
bool result = delegateMap[intent.Value]();
}
I won't answer to your question directly. #Abion47 has answered perfectly fine, i would answer the same.
But i think having having two dictionaries one having the token, and another having the delegate is more obscure then having single method for dispatching the result.
Here is my point with a bit code.
This the dictionary version.
var intentMap = new Dicionary<string, string>();
var delegateMap = new Dictionary<string, Func<bool>>();
delegate.Map.Add("TicketbookingInformation", BookTicket);
delegateMap.Add("OrderInformation", BookOrder);
Then the usage will be something like this
var token = ...;
if(intentMap.ContainsKey(token))
{
var delegateToken = intenMap[token];
if(delegateMap.ContainsKey(delegateToken))
{
var delegatedMethod = delegateMap(delegateToken);
return delegatedMethod();
}
}
So adding new token and delegate will means extending the dictionaries and i can't see how this is different then extending a switch statement.
Second version which i think will be generic enough and will need not too much modification where used will be something like this.
First i will suggest having the "TicketbookingInformation" and "OrderInformation" as enumeration type, this way having a switch statement will benefit from the compiler helping when you have some missing case to handle. This of course is applicable if you know upfront all the possible values ;]
bool PredicateDispatch(DelegateToken token)
{
switch(token)
{
DelegateToken.TicketbookingInformation: return BookTicket();
DelegateToken.OrderInformation: return BookOrder()
}
}
this way you will need to extend this single method to handle new tokens. It is more readable approach and you don't lose anything compared with the dictionary version. So i will do it this way. If don't have of course more complicated code and your example is more more simplified ;]
