Explanation

There is a syntax error in that line

so correct as

using static System.Console;

----

Main method where the program starts the execution there is a syntax error

so correct as

public static void Main(string[] arr)

---

There is a logical error in that following two statements ... it needs to be initialized

so fix the code as

double salary=0;
string salVal;
bool isValidSalary=false;

---

there is a syntax error

whenever using Write or WriteLine you should use

Console.Write()

Console.WriteLine()

--

it should be replaced with

catch(FormatException fe)

--

the paranthesis should be opened/closed correctly that also fixed in that code

---

given detailed explanation

all the best
