I have string string text = "1.2788923 is a decimal number. 1243818 is an integer. "; Is there a way to split it on the commas only ? This means to split on ". " but not on '.'. When I try string[] sentences = text.Split(". "); I get method has invalid arguments error..
Use String.Split Method (String[], StringSplitOptions) to split it like:
string[] sentences = text.Split(new string[] { ". " },StringSplitOptions.None);
You will end up with two items in your string:
1.2788923 is a decimal number
1243818 is an integer
You can use Regex.Split:
string[] parts = Regex.Split(text, #"\. ");
The string(s) that you splitting on are expected to be in a separate array.
String[] s = new String[] { ". " };
String[] r = "1. 23425".Split(s, StringSplitOptions.None);
Use Regular Expressions
public static void textSplitter(String text)
{
string pattern = "\. ";
String[] sentences = Regex.Split(text, pattern);
}

I have a text file where I have to split the values with every space (' ') and newline('\n'). It does not work very well since every newline has a carriage return connected to it (\r\n).
char[] param = new char[] {' ','\n','\r'}; // The issue
string[] input = fill.Split(param);
The param array does not accept a '\r\n' parameter as n split argument, that is why I used '\n' and '\r' separately, but it does not work the way it needs to work. Any suggestions?
Use the overload of String.Split() that takes an array of strings instead of the overload that takes an array of chars.
string[] result = text.Split(new string[] { " ", Environment.NewLine },
StringSplitOptions.None);
string fill = #"one two three four";
string[] result = fill.Split(new string[] { " ", Environment.NewLine },
StringSplitOptions.None);
foreach (var s in result)
{
Console.WriteLine(s);
}
Here is a DEMO.
But remember, Environment.NewLine is
A string containing "\r\n" for non-Unix platforms, or a string
containing "\n" for Unix platforms.
There is an overload that accepts strings:
string[] input = fill.Split(
new string[] { " ", Environment.NewLine },
StringSplitOptions.None);
You can also use Environment.NewLine instead of "\r\n".
But if you want to support all kinds of line-endings, you better specify all the popular possiblities:
string[] input = fill.Split(
new string[] { " ", "\n", "\r\n" },
StringSplitOptions.None);
I have written two lines of code below in vb6. The code is :
d = InStr(s, data1, Chr(13), 1) ' Fine 13 keycode(Enter) form a text data.
sSplit2 = Split(g, Chr(32)) ' Split with 13 Keycode(Enter)
But I can't write above code in C#. Please help me out. How can I write the above code in C#.
I believe you are looking for string.Split:
string str = "Test string" + (char)13 + "some other string";
string[] splitted = str.Split((char)13);
Or you can use:
string[] splitted = str.Split('\r');
For the above you will get two strings in your splitted array.
the equivalnt code for sSplit2 = Split(g, Chr(32)) is
string[] sSplit2 = g.Split('\n');
int index = sourceStr.IndexOf((char)13);
String[] splittArr = sourceStr.Split((char)13);
const char CarriageReturn = (char)13;
string testString = "This is a test " + CarriageReturn + " string.";
//find first occurence of CarriageReturn
int index = testString.IndexOf(CarriageReturn);
//split according to CarriageReturn
string[] split = testString.Split(CarriageReturn);
If you want to encapsulate the carriage return depending on whether you are running in a unix or non unix environment you can use Environment.NewLine . See http://msdn.microsoft.com/en-us/library/system.environment.newline(v=vs.100).aspx .
string testString2 = "This is a test " + Environment.NewLine + " string.";
//find first occurence of Environment.NewLine
int index2 = testString2.IndexOf(Environment.NewLine);
//split according to Environment.NewLine
string[] split2 = testString2.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
if i have a string like
string hello="HelloworldHellofriendsHelloPeople";
i would like to store this in a string like this
Helloworld
Hellofriends
HelloPeople
It has to change the line when it finds the string "hello"
thanks
string hello = "HelloworldHellofriendsHelloPeople";
var a = hello.Split(new string[] { "Hello"}, StringSplitOptions.RemoveEmptyEntries);
foreach (string s in a)
Console.WriteLine("Hello" + s);
var result = hello.Split(new[] { "Hello" },
StringSplitOptions.RemoveEmptyEntries)
.Select(s => "Hello" + s);
You can use this regex
(?=Hello)
and then split the string using regex's split method!
Your code would be:
String matchpattern = #"(?=Hello)";
Regex re = new Regex(matchpattern);
String[] splitarray = re.Split(sourcestring);
You can use this code - based on string.Replace
var replace = hello.Replace( "Hello", "-Hello" );
var result = replace.Split("-");
You could use string.split to split on the word "Hello", and then append "Hello" back onto the string.
string[] helloArray = string.split("Hello");
foreach(string hello in helloArray)
{
hello = "Hello" + hello;
}
That will give the output you want of
Helloworld
Hellofriends
HelloPeople
what is the efficient mechanism to remove 2 or more white spaces from a string leaving single white space.
I mean if string is "a____b" the output must be "a_b".
You can use a regular expression to replace multiple spaces:
s = Regex.Replace(s, " {2,}", " ");
Something like below maybe:
var b=a.Split(new char[] {' '}, StringSplitOptions.RemoveEmptyEntries);
var noMultipleSpaces = string.Join(" ",b);
string tempo = "this is a string with spaces";
RegexOptions options = RegexOptions.None;
Regex regex = new Regex(#"[ ]{2,}", options);
tempo = regex.Replace(tempo, #" ");
You Can user this method n pass your string value as argument
you have to add one namespace also using System.Text.RegularExpressions;
public static string RemoveMultipleWhiteSpace(string str)
{
// A.
// Create the Regex.
Regex r = new Regex(#"\s+");
// B.
// Remove multiple spaces.
string s3 = r.Replace(str, #" ");
return s3;
}
I want to split a string into an array. The string is as follows:
:hello:mr.zoghal:
I would like to split it as follows:
hello mr.zoghal
I tried ...
string[] split = string.Split(new Char[] {':'});
and now I want to have:
string something = hello ;
string something1 = mr.zoghal;
How can I accomplish this?
String myString = ":hello:mr.zoghal:";
string[] split = myString.Split(':');
string newString = string.Empty;
foreach(String s in split) {
newString += "something = " + s + "; ";
}
Your output would be:
something = hello; something = mr.zoghal;
For your original request:
string myString = ":hello:mr.zoghal:";
string[] split = myString.Split(new[] { ':' }, StringSplitOptions.RemoveEmptyEntries);
var somethings = split.Select(s => String.Format("something = {0};", s));
Console.WriteLine(String.Join("\n", somethings.ToArray()));
This will produce
something = hello;
something = mr.zoghal;
in accordance to your request.
Also, the line
string[] split = string.Split(new Char[] {':'});
is not legal C#. String.Split is an instance-level method whereas your current code is either trying to invoke Split on an instance named string (not legal as "string" is a reserved keyword) or is trying to invoke a static method named Split on the class String (there is no such method).
Edit: It isn't exactly clear what you are asking. But I think that this will give you what you want:
string myString = ":hello:mr.zoghal:";
string[] split = myString.Split(new[] { ':' }, StringSplitOptions.RemoveEmptyEntries);
string something = split[0];
string something1 = split[1];
Now you will have
something == "hello"
and
something1 == "mr.zoghal"
both evaluate as true. Is this what you are looking for?
It is much easier than that. There is already an option.
string mystring = ":hello:mr.zoghal:";
string[] split = mystring.Split(new char[] {':'}, StringSplitOptions.RemoveEmptyEntries);
