How to get a line from list by number using the webframe

[zenfreak]

I'm having troubles getting a line from list by number, mainly because I didn't fully understood how to work with this method here: https://help.zennolab.com/en/v5/zennoposter/5.11.3.0/webframe.html#topic759.html

Can someone provide a simple example for getting the 5th element from a list?

Hi.
The link you posted shows some random ranges from the list and not by line number.

To get a line by number:

var myListName = project.Lists["ProjectListName"];
return myListName[5];

Above code will return 5 line off list.

Simple and effective. Thank you!

Do you know why is it random1? Is there a random2 also ?

Well .. not as effective as I thought. First, getting the item like this

return project.Lists["List 1"].GetItem("random1(1,12-15,35-end)");

will extract the list element straight from that list without the need to create an additional list myListName and, more important, will let me choose if I also want to remove that item or not

So I would still want to know how to get the 5th element from a list using the webframe method so I will be able to also remove that element.

What I am really trying to achieve is to loop through the whole list and if I find a string element whose length is less than 100, then assign that string to a variable and delete the element from list. The list is also linked to a file with the property of saving the change list to file activated so I assume that line will be also deleted from the file.

var myListName = project.Lists["myAwesomeList"];
int countListElements=  myListName.Count();

for (int i = 0; i<countListElements; i++){
   
    int currentElementLength = myAwesomeList[i].Length;
    string currentElement =  project.Lists["myAwesomeList"].GetItem("random1(i)");
    project.SendInfoToLog(currentElement);
   
}

This code gives this error:
02:21:49 Perform the CSharp OwnCode Invalid format of the collection numbers. ElementsInCollection: 23. Path: random1(i)

If I replace random1(i) with random1(0) gives no error and spits the first element to the log, as it should. So how can I get an element by its position from myAwesomeList using the GetItem function so I can be able to also remove that element if necessary?

Found my answer.

This line should be

 string currentElement =  project.Lists["myAwesomeList"].GetItem(stringI, true);

where stringI is:

string stringI = i.ToString();

So GetItem expects a string value for the line number
