Simple OddNums IEnumerable

In our studying materials we have an example

 public static IEnumerable<int> OddNums(int n)
 {
    int i = –1;
    while (i < n – 1)
    {
       i += 2;  
       yield return i;
    }
  }

  static void Main(string[] args)
  {
    foreach (int i in OddNums(10))      
        Console.WriteLine("{0} ", i);
  }

However it throws errors on lines

int i = –1;
while (i < n – 1)

What is wrong?

Its hyphen instead of minus ...

Replace it by minus here:

 int i = -1;

and here:

while (i < n - 1)

In your code you are expecting - to be a minus sign which eventually seems to be a – hyphen

Try to change that by deleting it and then typing it again.

while (i < n - 1)
