You can do this:
var str = "asp,mvc,c#,wpf";
var anotherStr = "<b>asp</b>,<b>wpf</b>";
var myArr = anotherStr.Replace("<b>", "").Replace("</b>", "").Split(',');
foreach (string value in myArr)
{
str = str.Replace(value, "<b>" + value + "</b>");
}
Console.WriteLine(str);

string str = ""
if(something) {
str = "a"
} else {
str = "b"
}
Is this the cleanest way? or is there a better way to expose the str outside of conditional scope without this dirty empty string initialization
you could set it using a ternary operator in a single line. Something like
string str = something ? "a" : "b";

I have a string array with 3 elements like below for example.
string[] stringarray1;
stringarray1 = new string[5]{ “Element 1\n”, “Element 2\n”, “Element 3\n”, “Element 4\n”, “Element 5\nblablablabla” };
Here i need to check last element in string array having unnecessary dynamic text "\nblablablabla", if exists i need to remove(till last of the dynamic text) and replace with "Element 5\n" in last element.
How can I do this?
try this:
for (int i = 0; i < stringarray1.Length; i++)
{
stringarray1[i] = stringarray1[i].Split("\n")[0] + "\n";
}
You can split string with respect to "\n" and take first of it and add "\n" again. This will remove unnessesary characters from your string that i understand.
Instead of checking and replacing unnecessary text, you can replace what ever string you have with expected string
var lastIndex = stringarray1.Length -1;
stringarray1[lastIndex] = $"Element {lastIndex}\n";

My sentence is: !doar 12345, rayantt
Using string.Contains(!doar), I need get the other values as:
int mount = 12345;
string destiny = "rayannt";
Let the input be the input string as you stated in the question, searchString be the string that you wanted to search for; strParam and intParam are the two required outputs; Now consider the following code:
string input = "!doar 12345, rayantt";
string searchString = "!doar";
string strParam=string.Empty ;
int intParam=0;
if (input.Contains(searchString)) // check for the existence of the search string in given string
{
input = input.Replace(searchString, ""); // remove the searchstring from the input
string[] contents = input.Split(',');
int.TryParse(contents[0], out intParam); // collect the integer param
strParam=contents[1]; // collect the string param
}
// here you get 12345 in intParam and "rayantt" in strParam

I have a input string,
string str1 = "aabcccabdfa";
I want to count the occurrence of each character and put it next to that character. So I need to output result as "a4b2c3d1f1". How can i achieve this with LINQ?
I try with "Dictionary" to do that, but not able to do that.
Thanks,
Do it like this:
string str1 = "aabcccabdfa";
string.Concat(str1.GroupBy(c => c).OrderBy(c => c.Key).Select(c => c.Key.ToString() + c.Count()));
string str1 = "aabcccabdfa";
var result=string.Concat(str1.GroupBy(a=>a)
.Select(a=>a.Key.ToString()+a.Count().ToString()));
string str1 = "aabcccabdfa";
var output = "";
str1.ToArray().Distinct().ToList().ForEach(x => output += x + (str1.Count(f => f == x).ToString()));

class FunWithScheduling
{
static void Main()
{
StringBuilder newFile = new StringBuilder();
string temp = "";
string[] file = File.ReadAllLines(Scheduler.txt");
foreach (string line in file)
{
if (line.Contains("Subhadra"))
{
temp = line.Replace("Subhadra", "Thangam");
newFile.Append(temp + "\r\n");
continue;
}
newFile.Append(line + "\r\n");
}
File.WriteAllText("Scheduler.txt", newFile.ToString());
}
}
You are missing the opening quote in the following line:
string[] file = File.ReadAllLines(Scheduler.txt");
As such, the compiler is reading everything after that ending quote as the start of a string constant.
In order to fix this, you need to change the above line to the below, which has the opening quote:-
string[] file = File.ReadAllLines("Scheduler.txt");
