RegEx Starts with [ and ending with ]
(4 answers)
Closed 6 years ago.
How to replace a set of characters where I only know the first and the last one, in between is a variable that is not constant.
All I know is that this string will always start with & and it will end with ;
string str = "Hello &145126451; mate!";
How to get rid of &145126451; ?
So the desired result is:
string result = "Hello mate!"
The most easiest way is to use Regex:
Regex yourRegex = new Regex(#"&.*;");
string result = yourRegex.Replace("Hello &145126451; mate!", String.Empty);
Console.WriteLine(result);
Here is a fiddle with example.

Regex for numbers after a certain string part
(2 answers)
Closed 4 years ago.
I want to extract a character after a particular string, example:
Sentence: "Develop1 Tester2 BA3"
String: Develop
Expected result: "1"
I tried the Regex as following but still not get result as my expectation, please consult me, thank in advance.
RegEx: /[DEVELOP\d]\[+-]?\d+(?:\.\d*)?/
You don't really need a regex for this.
Something like this should do the trick:
var input = "Develop1 Tester2 BA3";
var search = "Develop";
if (input.StartsWith(search) && input.Length > search.Length) {
var result = input[search.Length];
Console.Write("Result: " + result);
}

How to find the second part of the string using substring in c#
I have follwwing string:
string str = "George Micahel R - 412352434";
I wanted the above string as two parts.Before "-" and after "-"
I have my first part using following code:
string firstPart = str.Substring(0,str.IndexOf(" - "));
When I am trying for the second part using the following code it gives me an error.
string secondPart = str.Substring(str.IndexOf(" - "), Len(str);
How to get the second part(only number)?
Thanks in advance.
Simply use split function:
var splittedArray = str.Split('-');
var leftPart = splittedArray[0];
var rightPart = splittedArray[1];
Use the Split() method instead.
string str = "George Micahel R - 412352434";
string[] words = str.Split('-');
Console.WriteLine(words[0].Trim()); # George Micahel R
Console.WriteLine(words[1].Trim()); # 412352434

Reference - What does this regex mean?
(1 answer)
Closed 5 years ago.
I'm looking for a way to find and extract the string matching a pattern in a string without a space :
string regexpattern = #"[A-Z]{4}\d{4}$"; // ex : BERF4787
string stringWithoutSpace = "stringsampleBERF4787withpattern";
string stringMatchPattern = ??? //I want to get BEFR4787 in this variable
You are almost there. The problem in your pattern is the $ which matches the end of a string. Since in your example the "BERF4787" is located in the middle of the string you should simply remove it:
string regexpattern = #"[A-Z]{4}\d{4}"; // ex : BERF4787
string stringWithoutSpace = "stringsampleBERF4787withpattern";
If you want to match your pattern in a string you can use the Regex.Match method which returns an object of type Match.
To get the matched value you need to use the Match.Value property like this:
string stringMatchPattern = Regex.Match(stringWithoutSpace, regexpattern).Value;

splitting a string based on multiple char delimiters
(7 answers)
Closed 5 years ago.
string test = "Account.Parameters[\"AccountNumber\"].Caption";
string new = test.Trim("[");
I want output "AccoutNumber".
I have tried the below code but not getting the desired result:
string[] test = "Transaction.Parameters[\"ExpOtherX\"].Caption".Split('[');
string newvalue = test[1];
Just use Split with two delimiters:
string[] test = "Transaction.Parameters[\"ExpOtherX\"].Caption".Split('[', ']');
string newvalue = test[1];
You can also use Regex:
string test = "Account.Parameters[\"AccountNumber\"].Caption";
var match = System.Text.RegularExpressions.Regex.Match(test, ".*?\\.Parameters\\[\"(.*?)\"]");
if (match.Success)
{
Console.WriteLine(match.Groups[1].Value);
}
.*? is a non greedy wildcart capture, so it will match your string until it reaches the next part (in our case, it will stop at .Parameters[", match the string, and then at "])
It will match .Parameters["..."]., and extract the "..." part.
you can do a Split to that string...
string test = "Account.Parameters[\"AccountNumber\"].Caption";
string output = test.Split('[', ']')[1];
Console.WriteLine(output);

How to remove all commas that are inside quotes (") with C# and regex
(3 answers)
Closed 3 years ago.
I want to replace all semicolons that are enclosed in quotation marks with a space. How can I do this in C#?
For example:
this string:
this is an example; "this is other ; example"
Would return:
this is an example; "this is other example"
I await your help!
Edited: This will work.
string yourString = "hello there; \"this should ; be replaced \"";
string fixedString = Regex.Replace(yourString, "(\"[^\",]+);([^\"]+\")", delegate (Match match)
{
string v = match.ToString();
return v.Replace(";", " ");
});
Try following :
string input = "this is an example; \"this is other ; example\"";
string pattern = "\"(?'prefix'[^;]+);(?'suffix'[^\"]+)\"";
string output = Regex.Replace(input,pattern,"\"${prefix} ${suffix}\"");
