How to get ListItem of the page in c#

So I found a code to edit a sharepoint page programmatically.

public static bool EditPage(SPClient.ListItem item, string pageTitle, string pageContent, string publishComment)
{
var pageEdited = false;
try
{
item["Title"] = pageTitle;
item["PublishingPageContent"] = pageContent;
item.Update();
SharePointTools.ClientContext.ExecuteQuery();
item.File.Publish(publishComment);
SharePointTools.ClientContext.ExecuteQuery();
pageEdited = true;
}
catch (Exception ex)
{
pageEdited = false;
}
return pageEdited;
So I got all my pages and how I can get an `SPClient.ListItem item` of every page.
