Reading numbers from a file

tomy batistakis

Dear all

I want to read a file ("test.txt") tha contains the following line and put the numbers in an array

" A 1.3     1.2              2.5       B"

As you can see the spaces between the characters are random

I know that it is extremely is to be done in C with the following way

   float A[3];
   char x1,x2;
   fp1=fopen("test.txt","r");
   fscanf(fp1,"%c %f %f %f %c \n",&x1,&A[0],&A[1],&A[2],&x2);
   fclose(fp1);

Can someone tell me how can I do it in C#?

Thanks in advance

Hi,
Try this
static void Main(string[] args)
{
StreamReader sr = File.OpenText(@"c:\test.txt");
string line = sr.ReadLine();
string[] items = line.Split(' ');
string[] numbers = new string[3];
int index =0;
foreach (string item in items)
{
float result = 0;
bool flag = float.TryParse(item, out result);
if (flag)
{
numbers[index] = item;
index++;

}

}
}
