Removing white spaces from an ArrayList
-
Hi all I have two problems ist one is that I have stored a string in ArrayList using split function (i.e one word per index). now the problem is that this ArrayList contains white spaces wich is creating problems as well. whereas i have already removed the white spaces from the string :( 2ndly i want to convert an ArrayList into a string. not an array of strings but a single string... looking forward to ur help Regards, -- modified at 13:53 Tuesday 9th May, 2006

friend this may resolve, ur first problem..
private void parseString(String x) { string tempstr; int i=0,len,flag=0; tempstr=""; len=x.Length; while(i < len) { if(x[i]!= ' ') { tempstr = tempstr + x[i]; flag = 0; } else { if(flag == 0) { str.Add(tempstr); tempstr = ""; flag = 1; index++; } } i++; } str.Add(tempstr); }In this str is arraylist If u have still some doubt, mail me ShivaJee -

In .NET 2.0 you can use the StringSplitOptions.RemoveEmptyEntries with the String.Split function. Otherwise when you load up your ArrayList just check if the strings contain only white space:
if (myString.Trim()="") // string is nothing but white space so don't add it to your arraylist
To convert back to a string can't you just iterate through the ArrayList and add each entry to a string, or even a StringBuilder? -- modified at 16:53 Tuesday 9th May, 2006 -

Use foreach to iterate over the array and a stringbuilder and ToString ( if you're not using a string in your foreach ) to pass each object through the stringbuilder to build up your string. Christian Graus - Microsoft MVP - C++
