I have an array which I split on basis of comma "," but there is a last entry as empty because I am concatenating it in jquery. I used

Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

but it removes all the empty entries from an array e.g. if my array is

 "1"," ","2","3"," " 

it returns 1,2,3. But I want it to remove only the last one from it e.g. return 1," ",2,3. Is it possible to do it without substracting 1 from the array?

You can use TrimEnd method to remove whitespaces from end on the String instance before calling Split:

string input = "1,2,3, ,4, , ";
   .Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

Output Array:

["1"," ","2","3"," ","4"," "]

How to exclude empty array (null value) while using String.Split , To remove the empty values, we need to just add the second parameter to the Split method. String. Split method is overloaded and String. Split(Char[], StringSplitOptions) is one of them. Console.WriteLine("After removing ""lazy"":") PrintValues(myAL) ' Removes the element at index 5. myAL.RemoveAt(5) ' Displays the current state of the ArrayList. Console.WriteLine("After removing the element at index 5:") PrintValues(myAL) ' Removes three elements starting at index 4.

First, use TrimEnd to prevent the aforementioned edge case and then split:

input.TrimEnd(' ',',').Split(new char[] {','}, StringSplitOptions.None);

c#, Split(new char[]{','},StringSplitOptions.RemoveEmptyEntries); //another option to split array and remove empty substring //string[] splittedArray = plants.Split(new  ArrayList.RemoveAt(Int32) method is used to remove the element at the specified index of the ArrayList. Properties: Elements can be added or removed from the Array List collection at any point in time. The ArrayList is not guaranteed to be sorted. The capacity of an ArrayList is the number of elements the ArrayList can hold.

If we want to skip all whitespace only items starting from end let's Reverse, then SkipWhile (as usual) the items we want to get rid of and, finally, Reverse back again:

  string input = "1,2,3, ,4, , ";

  ["1", "2", "3", " ", "4"]
  string[] array = input
    .Split(',') // it seems we don't want to remove empty in the middle
    .SkipWhile(item => item.All(c => char.IsWhiteSpace(c)))

If you want all items except last one:

  // All items
  string[] array = input

  // Removing the last item: ["1", "2", "3", " ", "4", " "]
  Array.Resize(ref array, array.Length - 1);

String.Split Method (System), You can specify whether the substrings include empty array elements. For example, the Split method cannot be used to split the following string, because the delimited by various combinations of hyphens and other characters. C# Copy current string instance of the last occurrence of any character in a character array. In this article we will discuss different ways to delete elements from a Numpy Array by matching value or based on multiple conditions. Remove all occurrences of an element with given value from numpy array

You can also try this Code to remove last element (if (Last_Element == " ")) of array.

class Program
    static void Main(string[] args)
         // Simple Array:
         string[] array = new string[] { "1" , "2" , "3" , "4" , "5" , " "};

         // Converting Array into a List. (Because we don't have any remove method for array.)
         var arrayList = array.ToList();

         // Retrieving last element.
         string _lastSpace = arrayList.Last();

         // Confirmation: Last Element is space or not.
         if(_lastSpace == " ")
             arrayList.RemoveAt(arrayList.LastIndexOf(" "));

         // Converting the list without having last Element with space to "array"
         array = arrayList.ToArray();

Split string or character vector at specified delimiter, C , matches ] = strsplit(___) additionally returns the array, matches . This empty character vector follows the last matched delimiter. delimiter can include the following escape sequences: If false , then consecutive delimiters are treated as separate delimiters, resulting in empty character vector '' elements between  Example 2. Now, let’s say you want to delete everything after or before a substring in a string.
