I am trying to make a simple query to sharepoint online using Azure function created in VS2017.

My code looks like below:

List mylist = myweb.Lists.GetByTitle(listName);
CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml = "<View><Query><Where><Neq><FieldRef Name='RequestedForDeletion' /><Value Type='Boolean'>False</Value></Neq></Where></Query><ViewFields><FieldRef Name='LinkTitle' /><FieldRef Name='SiteUrl_x0028_alias_x0029_' /><FieldRef Name='RequestedForDeletion' /><FieldRef Name='CurrentStatus' /></ViewFields><QueryOptions /></View>";
ListItemCollection items = mylist.GetItems(camlQuery);
myclientContext.Load(items);
myclientContext.ExecuteQuery();
log.Info($"Empty items: {items.Count}");

It is the myclientContext.ExecuteQuery(); where I get error as : "The remote server returned an error: (400) Bad Request"

I am unable to understand the reason for this error. Any help or explanation.

The reason why you are getting this error is because CamlQuery.ViewXml property expects a valid CAML query enclosed within View element.

Here are a few examples on how to construct a CAML query:

For empty query

 var camlQuery = new CamlQuery();
 camlQuery.ViewXml = "<View/>";

For predefined query

var camlQuery = CamlQuery.CreateAllItemsQuery();

For user-defined query:

var camlQuery = new CamlQuery();
                camlQuery.ViewXml = "<View Scope =\"RecursiveAll\"><Query><Where><Eq><FieldRef Name=\"FSObjType\" /><Value Type=\"Integer\">1</Value></Eq></Where></Query></View>";
