I have the string
"{ "type" : "Stage_FF_Hot_Alerts__c"}"
I want to it be
{ "type" : "Stage_FF_Hot_Alerts__c"}
i.e. I want to remove quotes from start and end. How can I achieve this?


You could use Trim:
var a = "\"{ \"type\" : \"Stage_FF_Hot_Alerts__c\"}\"";
var b = a.Trim('"');
Console.WriteLine(a);
Console.WriteLine(b);
It will remove all leading and trailing quotation marks.
Try it online


You can also use:
var quotedString = "\"hello\"";
var unQuotedString = quotedString.TrimStart('"').TrimEnd('"');

I would like to exclude a specific string when it is contained in an expression:
Example:
myurl.htm = exclude
myurl = include
I tried this one : ([a-z0-9]+)(?!.htm)
But looks like it doesn't work.

Try the following:
([a-z0-9]+)(?!^\.htm)
You had two errors in your expression:
You have to escape the dot . with a backslash because it means "matches any character (except newline)" unescaped.
You have to add a ^ to prevent cutting of the last character.
You can test your expression on this website: https://regex101.com/

I have a string like below
he/a0h/a0dv/a0jks
I would like to be string become as below.
hehdvjks
Need to remove the "/a0" from the string.

The String.Replace method is what you're looking for, just do a;
String myString = "he/a0h/a0dv/a0jks"
myString = myString.Replace("/a0", "")
It'll return a modified 'myString' with all occurrences of the old value ("/a0") replaced with a new value (blank in this case).
The MSDN reference for String.Replace can be found at:
http://msdn.microsoft.com/en-us/library/fk49wtc1%28v=vs.110%29.aspx

var result = "he/a0h/a0dv/a0jks".Replace("/a0", string.Empty);

I am trying read one string from TextBox and use in my script.
Suppose this TextBox name is: txt3.
I want read this value and use in below lines:
string s = Regex.Replace(str,
#"\btxt3.Text\b",
txt4.Text,
RegexOptions.IgnoreCase);
How I can write this #"\btxt3.Text\b" ?
I want write that as :
string str==#"\btxt3.Text\b";

You want something like:
String.Format(#"\b{0}\b", txt3.Text)

Try this
string s = Regex.Replace(str, string.Format(#"\b{0}\b",txt3.Text), txt4.Text, RegexOptions.IgnoreCase);

If you want to combine value of txt3 with other strings, one way to do it is write
"\\b" + txt3.Text + "\\b"
instead of
#"\btxt3.Text\b"

I want to get the previous chars from a certain char in a string.
For example: myString = "26+", so I want to get 26 without +. How can I do this?

Use Substring and IndexOf.
string str = "26+";
string requiredString = str.Substring(0, str.IndexOf('+'));
strings are immutable in C# and you have to assign the results to string itself or some other string.

The function String.Substring will do what you need.
yourString.Substring(0, keepCharactersBeforeHere);
