C# -jQuery like function chaining is possible in C#?

As I am new to C# ,just wish to know, can i perform function chaining in C# like jQuery ?

Example jQuery :

$("#gview tbody tr")
   .not(":first,:last")
   .filter(":odd") 
   .addClass("someclass")
   .css("border","solid 1px grey");

Note : I don't mean clientside script.My only concern is function chaining is possible in C# or not

Yes you need to look into using the Builder Pattern modified to return the object being worked on.

Example:

public class SomeClass
{
    public SomeClass doSomeWork()
    {
        //do some work on this
        this.PropertyA = "Somethign";

        return this;
    }
}

This is also referred to as a chaining design pattern.

Yes. I use it regularly, for example with a StringBuilder:

string s =
   new StringBuilder()
   .Append(year)
   .Append('-')
   .Append(month)
   .Append('-')
   .Append(day)
   .ToString();

Or with my own library for creating HTML controls:

Container.Controls.Add(
   Tag.Div.CssClass("item")
   .AddChild(Tag.Span.CssClass("date").Text(item.Date))
   .AddChild(Tag.Span.CssClass("title").Text(item.Title))
);

Yes, and there are several good examples of how it can be done. For example, take a look at Fluent NHibernate.

You can call one function from another just like most programming languages... it all depends on how you build.

You could have an object as such:

public class DoMath
{
    private int Add2(int piNumber)
    {
        return piNumber + 2; 
    }
    private int Divideby7(int piNumber)
    {
        return Divideby7(this.Add2(piNumber));
    }
}

yes, try this

var s = 19.ToString().Replace("1"," ").Trim().ToString("0.00");

Yes, you can, but as with jQuery, the functions you want to chain must be built for it. If you build your own, just return the object the caller should chain on. One example of chaining in C# is Fluent nHibernate.

Yes, just return the current object (this), and you can chain as much as you want. It's also called fluent interface
