Force checkout documents library in SharePoint online using CSOM

Question

Hi,

I am trying to force checkout the documents present in the 'Documents' library in SharePoint Online using CSOM. Please see the code snippet below -

                        newContext.Load(newContext.Web);
                        newContext.Load(newContext.Site);    
                        List olist = newContext.Web.Lists.GetByTitle("Documents");
                        olist.ForceCheckout = true;
                        olist.Update();                        
                        newContext.ExecuteQueryAsync().Wait();

But doing so doesn't force the user to checkout documents prior to modification. What is the best way to require the documents to be checked out programmatically in C#? Any help is greatly appreciated. Thank you in advance.

Regards
SLS

Hi @sravya shivapuram ,
list.ForceCheckout will only set the list property to check out which means all files new added will be checked out but the files already exist still keep check in. Please refer to following code to check out exist files

File file = ctx.Web.GetFileByServerRelativeUrl("/sites/xxx/TestFolder/test.txt");  
file.CheckOut();  
ctx.Load(file);  
ctx.ExecuteQuery();  

==================
Solution Updated==================

I have tested the following code and set the Require Check Out property successfully.

List olist = ctx.Web.Lists.GetByTitle("TestFolder");  
olist.ForceCheckout = true;  
olist.Update();  
ctx.ExecuteQuery();
