.Net Framework 4.0 – New Entries

It seems I am posting after so many days!!!


I have just started playing with VS 2010 and started to find out so many cool inclusions.
Here are few of them… I will keep rolling this post – anybody wants to add to the ever growing list is most welcome… J

.Net 4.0 Newbie => SortedSet and StringBuilder.Clear()		Here comes our sorted list: 1 2 3 4 5 6 7 8 9
.Net 4.0 Newbie => String.IsNullOrWhiteSpace(param)		New method has discoverd WhiteSpace in param
.Net 4.0 Newbie => Stopwatch.Restart()		Elapsed Time in mSec Before Stopwatch Restarted = 5
.Net 4.0 Newbie => String.Concat		MNOPQRSTUVWXYZ

The sample code is given below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Text;
using System.Diagnostics;

namespace LearningDotNet4
{

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

var sSet = new SortedSet<int> { 2, 4, 6, 8, 9, 1, 3, 5, 7 };
var sBulder = new StringBuilder();

sBulder.Append("Here comes our sorted list: ");

//Getting directly the sorted output
foreach (int iVal in sSet)
{
string strVal = iVal.ToString();
sBulder.Append(strVal + '\t');
}

Label2.Text = sBulder.ToString();
sBulder.Clear();

String strData = " ";


sw.Start();

for (int i = 0; i < 1000000; i++)
{//Do something
//....
//ERROR!!!}

Label6.Text = "Elapsed Time in mSec Before Stopwatch Restarted = " + sw.ElapsedMilliseconds.ToString();

//Restart the Stopwatch
sw.Restart();

string output = String.Concat(GetAlphabet(true).Where(letter => letter.CompareTo("M") >= 0));
Label8.Text = output;
}

 private static List<string> GetAlphabet(bool upper)
{List<string> alphabet = new
List<string>();
int charValue = upper ? 65 : 97;
for (int ctr = 0; ctr <= 25; ctr++)
alphabet.Add(Convert.ToChar(charValue + ctr).ToString());
return alphabet;
}
}
}
if (String.IsNullOrWhiteSpace(strData)){Label4.Text = "New method has discoverd WhiteSpace in param";}
Stopwatch sw = new Stopwatch();
