String.Contains Case Sensitive

String.Contains Case Sensitive
Case Sensitive String.Contain
String.Contains vs IndexOf .Net

I encountered an issue with string contains couple of days ago... well, the fact is - it has no
StringComparison for culture and Case Sensitivity.

I found a better way to do this, and I just wanted to share in a short post:

        string bookTitle = "The Old Man and the Sea";

        if (bookTitle.IndexOf("the old man") > -1)
        {
            // this is case sensitive
        }
        if (bookTitle.IndexOf("the old man", StringComparison.OrdinalIgnoreCase) > -1)
        {
            // this is ignore case
        }

There are some more options in the StringComparison , but I'll leave it to you to play with

Ajax For Dummies in Asp.Net

Ajax for Dummies with Asp.Net. 
Ajax for Dummies with JQuery.
.Net WebMethods

Couple of weeks ago a friend of mine went to a job interview for a junior developer position.  After the interview he came back and complained about his Ajax skills.
Well, Noam, this is for you:

First open a new ASP.Net web application (or website, doesn't really matter).
Make sure you have JQuery in your website.

Create a new ASPX page.  lets call it, WebMethods.aspx
At the top of the page add "using System.Web.Services;"

Create a method called "AjaxForDummies()" and place a "[WebMethod]" attribute for it. This method will not accept parameters but will return a string to the server.

Create another method called "AjaxForDummies2(string name, string sDate) "
this method will accept 2 parameters and returns a string to the server.



The JavaScript code is actually very simple:
At the HTML part of the page place a simple code:


Pay Attention:
1. Always make sure your root on the properties.
2. Method should be static.
3. creating methods with the same name (overloading) is problematic.

Have fun,
