Convert String Builder to Integer in c#

Question

I am new programmer in C# and I wanna know if there is a direct way to convert from StringBuilder to int. I have the following code. On the last line of the code I get an error.

StringBuilder newnum = new StringBuilder();
for (int i = x.Length - 1; i >= 0; i--)
{
    newnum.Append(x[i]);  
}
int x = Convert.ToInt32(newnum);

Answer 1

You can solve this problem by simply converting the StringBuilder to String before passing it to the Convert.ToInt32 method;

You have three different options for converting textual data to an Integer:

1:
int i = int.Parse(sb.ToString());

2:
int i = Convert.ToInt32(sb.ToString());

3:
int i;
int.TryParse(sb.ToString(), out i);

Answer 2

int x = Convert.ToInt32(newnum.ToString());
