Looking for C# equivalent of scanf

Question

I used to code in C language in the past and I found the scanf function very useful. Unfortunately, there is no equivalent in C#.

I am using using it to

Answer 1

I have found a better solution than using sscanf from C or some rewritten part by someone (no offence)

http://msdn.microsoft.com/en-us/library/63ew9az0.aspx have a look at this article, it explains how to make named groups to extract the wanted data from a patterned string. Beware of the little error in the article and the better version below. (the colon was not part of the group)

using System;
using System.Text.RegularExpressions;

public class Example
{
   public static void Main()
   {
      string url = "http://www.contoso.com:8080/letters/readme.html";
      Regex r = new Regex(@"^(?<proto>\w+)://[^/]+?(?<port>:\d+)?/",RegexOptions.None, TimeSpan.FromMilliseconds(150));
      Match m = r.Match(url);
      if (m.Success)
         Console.WriteLine(r.Match(url).Result("${proto}:${port}")); 
   }
}
// The example displays the following output: 
//       http::8080

You could use System.IO.FileStream, and System.IO.StreamReader, and then parse from there.

Answer 3

Although this looks sort of crude it does get the job done:

// Create the stream reader
sr = new StreamReader("myFile.txt");

// Read it
srRec = sr.ReadLine();

// Replace multiple spaces with one space
String rec1 = srRec.Replace("          ", " ");
String rec2 = rec1.Replace("         ", " ");
String rec3 = rec2.Replace("        ", " ");
String rec4 = rec3.Replace("       ", " ");
String rec5 = rec4.Replace("      ", " ");
String rec6 = rec5.Replace("     ", " ");
String rec7 = rec6.Replace("    ", " ");
String rec8 = rec7.Replace("   ", " ");
String rec9 = rec8.Replace("  ", " ");

// Finally split the string into an array of strings with Split
String[] srVals = rec9.Split(' ');

You can then use the array srVals as individual variables from the record.
