String.Equals vs String.Compare vs “==” in Action. Explanation needed

Question

Following is the code snippet from a console application -

class MyClass
{        
   public int GetDay(string data22)
    {
        int returnValue = 0;

              


        

Answer 1

There is an "invisible" character at the beginning of your

string ExecutionDay = "‎THURSDAY";

and it is the LEFT-TO-RIGHT MARK. You can check it with:

int len = ExecutionDay.Length; // 9 instead of 8

and

char ch = ExecutionDay[0]; // 8206
