For Example, I have a string like :
string str = "santhosh,phani,ravi,phani123,praveen,sathish,prakash";
I want to delete the charaters ,phani from str.
Now, I am using str = str.Replace(",phani", string.Empty);
then my output is : str="santhosh,ravi123,praveen,sathish,prakash";
But I want a output like : str="santhosh,ravi,phani123,praveen,sathish,prakash";

Using 'str. replace() , we can replace a specific character. If we want to remove that specific character, replace that character with an empty string. The str. replace() method will replace all occurrences of the specific character mentioned.
If you are having a string with special characters and want's to remove/replace them then you can use regex for that. Use this code: Regex. Replace(your String, @"[^0-9a-zA-Z]+", "")
Python Remove Character from String using replace() We can use string replace() function to replace a character with a new character. If we provide an empty string as the second argument, then the character will get removed from the string.
Logic to remove all occurrences of a characterRun a loop from start character of str to end. Inside the loop, check if current character of string str is equal to toRemove. If the mentioned condition is true then shift all character to one position left from current matched position to end of string.
string str = "santhosh,phani,ravi,phani123,praveen,sathish,prakash";
var words = str.Split(',');
str = String.Join(",", words.Where(word => word != "phani"));
the better choice is to use a Split and Join method. Easy in Linq :
String str = "santhosh,phani,ravi,phani123,praveen,sathish,prakash";
String token = "phani";
String result = String.Join(",", str.Split(',').Where(s => s != token));
(edit : I take time for testing and i'm not first ^^)
