  (small amendment)Amending this code to find max and lower limits

  Dec 03, 2012 05:16 PM|LINK

  Now i have this piece of code already from this forum, works perfectly though my needs have slightly changed 'since testing!'

  The code finds 2 numbers from the string.

  then tests my variable against these numbers, if below/above by more than 1 gives no matched.

  Else if varied by 1 gives Variation and if between the numbers gives Matched.

  Here is the code.

  public static string TestMatch(string range, int comp)
  {
            
  string result = "Not Matched";
     
    if (string.IsNullOrEmpty(range) || comp < 0)
      {
          result = "";
      }
      else
      {
       
      // removes characters from the string
      // (http://stackoverflow.com/questions/4366422/how-to-remove-characters-from-a-string-using-linq)
      string strDigits = new String(range.Where(Char.IsDigit).ToArray());
       
      // creates upper and lower limits
      int lower = (strDigits.Length > 0 ? Convert.ToInt16(strDigits.Substring(0,1)) : 0);
      int upper = (strDigits.Length > 1 ? Convert.ToInt16(strDigits.Substring(1,1)) : lower);
       
      // compares values
      if (comp >= lower && comp <= upper)
      {
          result = "Matched";
      }
      else if (comp >= (lower - 1) && comp <= (upper + 1))
      {
          result = "Variation";
      }
  }
       
  return result;
  }

  
  My change is that the variable string, which above is 'range' could now contain 3 or more numbers.

  The good thing is the reamining code already wil match if between the 2, so rather than pulling the first 2 digits it can find for 'lower' and 'upper' I now need 'lower' and 'upper' to be the biggest/smallest number found in the string respectively. If only single number found then will act the same as it does.

  I am sure this is easy and i thought i understood the code, however making this amendment is beyond me!

  would like to say many many thanks in advance

  @{
  
  
  var input = "281379465";
  var strDigits = new String(input.Where(Char.IsDigit).ToArray());
  var max = (int)strDigits.Max();
  var min = (int)strDigits.Min();
  foreach(var d in strDigits)
  {
      @d    @((int)d>min && (int)d<max?" inRange":(int)d==min?" is the minimum":" is the maximum")   <br />
  }
  
  
  }

  .min()
  .max()

  find the highest/lowest single digit in a string?

  For instance my wont have spaces between the numbers?

  If this is true could i amend my code like the following?

  public static string TestMatch(string range, int comp) 
  { 
             
  string result = "Not Matched"; 
      
    if (string.IsNullOrEmpty(range) || comp < 0) 
      { 
          result = ""; 
      } 
      else 
      { 
        
      // removes characters from the string 
      // (http://stackoverflow.com/questions/4366422/how-to-remove-characters-from-a-string-using-linq) 
      string strDigits = new String(range.Where(Char.IsDigit).ToArray()); 
        
      // creates upper and lower limits 
      int lower = (strDigits.max()); 
      int upper = (strDigits.min()); 
        
      // compares values 
      if (comp >= lower && comp <= upper) 
      { 
          result = "Matched"; 
      } 
      else if (comp >= (lower - 1) && comp <= (upper + 1)) 
      { 
          result = "Variation"; 
      } 
  } 
        
  return result; 
  }

  My change is that the variable string, which above is 'range' could now contain 3 or more numbers.

  Try amending your function as follows:

  public static string TestMatch(string range, int comp)
  {
      string result = "Not Matched";
     
      if (string.IsNullOrEmpty(range) || comp < 0)
      {
          result = "";
      }
      else
      {
       
          // removes characters from the string
          // (http://stackoverflow.com/questions/4366422/how-to-remove-characters-from-a-string-using-linq)
          string strDigits = new String(range.Where(Char.IsDigit).ToArray());
       
          // creates upper and lower limits
          int lower = (strDigits.Length > 0 ? (int)strDigits.Min() - 48 : 0);
          int upper = (strDigits.Length > 1 ? (int)strDigits.Max() - 48 : lower);
       
          // compares values
          if (comp >= lower && comp <= upper)
          {
              result = "Matched";
          }
          else if (comp >= (lower - 1) && comp <= (upper + 1))
          {
              result = "Variation";
          }
      }
       
      return result;
  }
