I have a string array. I need to remove some items from that array. but I don't know the index of the items that need removing.
My array is : string[] arr= {" ","a","b"," ","c"," ","d"," ","e","f"," "," "}.
I need to remove the " " items. ie after removing " " my result should be arr={"a","b","c","d","e","f"}
how can I do this?
string[] arr = {" ", "a", "b", " ", "c", " ", "d", " ", "e", "f", " ", " "};
arr = arr.Where(s => s != " ").ToArray();
This will remove all entries that is null, empty, or just whitespaces:
arr.Where( s => !string.IsNullOrWhiteSpace(s)).ToArray();
If for some reason you only want to remove the entries with just one whitespace like in your example, you can modify it like this:
arr.Where( s => s != " ").ToArray();
Using LinQ
using System.Linq;
string[] arr= {" ","a","b"," ","c"," ","d"," ","e","f"," "," "}.
arr.Where( x => !string.IsNullOrWhiteSpace(x)).ToArray();
or depending on how you are filling the array you can do it before
string[] arr = stringToBeSplit.Split('/', StringSplitOptions.RemoveEmptyEntries);
then empty entries will not be put into your string array in the first place
You can use Except to remove blank value
string[] arr={" ","a","b"," ","c"," ","d"," ","e","f"," "," "}.
arr= arr.Except(new List<string> { string.Empty }).ToArray();
