Converting ListItemCollection to DataTable in Client side object model for SP Online

Converting ListItemCollection to DataTable in Client side object model for SP Online

Dewadatta Avasare 0

Is there any way to convert ListItemCollection to a datatable like we could do in Sharepoint server side code using
SPListItemCollection listcol= listname.GetItems(query);
DataTable datatableOne= new DataTable();
if (listcol!= null && listcol.Count > 0)
{
datatableOne= listcol.GetDataTable();
}
Is there any GetDataTable method for CSOM because I am unable to find one in documentation for SP Online.
Help would be much appreciated.

Hi anonymous user ,
There is no similar method in CSOM (C#). You have to build manually as like following code.

You can check the methods of ListItemCollection from the document

This is working but it is taking all the columns including the following columns:
MetaInfo
_ModerationStatus
_Level
UniqueId
owshiddenversion
FSObjType
Created_x0020_Date
Created
Title
FileLeafRef
Modified
FileRef

I edited the load by using : clientContext.Load(listItems, items => items.Include( item => item.Id, item => item.DisplayName, item => item.HasUniqueRoleAssignments));

but that doesn't display anything neither the column names nor the data in the list which the context.web.list is accessing even though it has 123 in ReqNo as defined in the CamlQuery , is there a way to fetch specific columns? like given in the attached txt file: ID and ReqNo columns

Hi anonymous user ,
You can refer to the below code to get specified columns

            Microsoft.SharePoint.Client.CamlQuery camlQuery = new CamlQuery();  
            camlQuery.ViewXml =  
            @"<View>" +  
            "<Query> " +  
                "<Where>" +  
                    "<And>" +  
                            "<IsNotNull><FieldRef Name='ID' /></IsNotNull>" +  
                            "<Eq><FieldRef Name='ReqNo' /><Value Type='Text'>123</Value></Eq>" +  
                    "</And>" +  
                "</Where>" +  
            "</Query> " +  
            "<ViewFields>" +  
                "<FieldRef Name='ID' />," +  
                "<FieldRef Name='ReqNo' />" +  
            "</ViewFields>" +  
            "</View>";  

            ListItemCollection listItems = spList.GetItems(camlQuery);  
            clientContext.Load(listItems, singleitem => singleitem.Include(item => item["ID"],item => item["ReqNo"]));  
            clientContext.ExecuteQuery();
