Newbie need help understanding multi parameter lambda?

Hi Laxman 

 

I modified the code something like  

and putting the break point  you will get the following : 

 

 So i = 0,  deqn.Substring(i)  = "\\tagSIGMA INSTITUTE", c ="",

      i = 1, deqn.Substring(i) = "\\tagSIGMA INSTITUTE", c ="\\",

      i = 2 , deqn.Substring(i) = "tagSIGMA INSTITUTE", c ="t",

                                       .........

                                       .........

Hi Mukesh,

 Are the below strings values of "c" in the lambda?

or are they the value of "i"?

Sorry if this question sounds stupid but I'm a newby:)

hi mukesh

The first is the iterated charecter

second is the position(index) of the iterated charecter 

Hi Laxman ,

 

Now there is 2 extension for the select . Please refer the image below : 

 

First extension in the image above is having one parameter  which is just element itself to be manipulated.

Now in the second case it is accepting  2 parameter where the first parameter is the element itself and second parameter is the index.

 

Now in you code using second parameter you are iterating through the all the value using substring. For example if your deqn.value = "\\tag SIGMA INSTITUTE" so it will iterate and get all the value such as 

\\tagSIGMA INSTITUTE    (i = 0)

tagSIGMA INSTITUTE (i=1)

agSigMA INSTITUTE (i = 3)

..

..

E (i = n)

 

then from all this element its checking where there \\tag  

 and getting count.

sir I made some changes with your code and bellow given a example .sir I look it and get back to me
