How can I count the number of elements in IEnumerator?

Question

I am getting all files in a directory by following code.

IEnumerator FILES = Directory.GetFiles(
                DIRECTORY_PATH).GetEnumerator();

How can I get the total number of files? There's no FILES.Count();

Answer 1

Directory.GetFiles(@"C:\yourdir").Length

直接给你数

Answer 2

First you can get your files string[] , count the numbers in it, then get your enumerator:

string[] files = Directory.GetFiles(DIRECTORY_PATH);
int count = files.Length;
IEnumerator enumerator = files.GetEnumerator();

Answer 3

If you really want to stick with " GetEnumerator() " ...

IEnumerator files = Directory.GetFiles(DIRECTORY_PATH).GetEnumerator();
int count = 0;
while (files.MoveNext())
{
    count++;
}

// after this loop you will have total files count in count varibale.
