Answer 1

If you have defined a link field for the folder contenttype then you can add a link to that field using the FieldUrlValue class in CSOM.

FieldUrlValue link = new FieldUrlValue(); 
                link.Url = "http://microsoft.com"; 
                link.Description = "Microsoft Technologies";
                lstItem["DocLink"] = link;
                lstItem.Update();
                clientContext.ExecuteQuery();

Correct me if I'm wrong, to create link thru COM, first I have to define a link field for the document library inside which im trying to create the link?

So the snippet you have send, DocLink is the link field which needs to be created? please help with some e.g

Here is some sample code to add a URL field to a list using CSOM.

public static void AddLinkField()
{
            ClientContext context = new ClientContext("http://basesmc2008");
            Web site = context.Web;
            string linkSchema = @"<Field Type='URL' DisplayName='DocLink'
                                Required='FALSE' EnforceUniqueValues='FALSE' 
                                Indexed='FALSE' Format='Hyperlink' 
                                ID='{b3126091-bbc7-4ee1-b4ff-05f520cad1d8}' 
                                SourceID='{354fc616-433b-4a49-a44a-990e299d6b11}' 
                                StaticName='DocLink' Name='DocLink'  /> ";
            ClientContext clientContext = new ClientContext("http://basesmc2008");
            List list = clientContext.Web.Lists.GetByTitle("tester");
            FieldCollection fields = list.Fields;
            clientContext.Load(list);
            clientContext.Load(fields);
            clientContext.ExecuteQuery();
            Field linkField = fields.AddFieldAsXml(linkSchema, true, AddFieldOptions.AddToAllContentTypes);
            linkField.Update();
            clientContext.Load(linkField);
            clientContext.ExecuteQuery();
        }

Hello Steve,

Thanks a lot for your inputs, I tried to put this snippet in a console application to run and check , first time it ran but I did not see any link, second time I tried running it,it says...

ID='{b3126091-bbc7-4ee1-b4ff-05f520cad1d8}' already exists...

So I do not know how do I check where it created, and how do I generate this linkschema? may be very basic question but if you can help to clear this out I would be very grateful. My Code

 var credentials = new NetworkCredential("Mishas50", "**********", "Enterprise");


            ClientContext context = new ClientContext("http://daywinwebp003:17362/sites/DEVDOCLIB");
            Web site = context.Web;
            string linkSchema = @"<Field Type='URL' DisplayName='DocLink'
                                Required='FALSE' EnforceUniqueValues='FALSE'
                                Indexed='FALSE' Format='Hyperlink'
                                ID='{b3126091-bbc7-4ee1-b4ff-05f520cad1d8}'
                                SourceID='{354fc616-433b-4a49-a44a-990e299d6b11}'
                                StaticName='DocLink' Name='DocLink'  /> ";
            ClientContext clientContext = new ClientContext("http://daywinwebp003:17362/sites/DEVDOCLIB");
            List list = clientContext.Web.Lists.GetByTitle("PortalDevDoc");
            FieldCollection fields = list.Fields;
            clientContext.Load(list);
            clientContext.Load(fields);
            clientContext.ExecuteQuery();
            Field linkField = fields.AddFieldAsXml(linkSchema, true, AddFieldOptions.AddToAllContentTypes);
            linkField.Update();
            clientContext.Load(linkField);
            clientContext.ExecuteQuery();

Hello,

Can you put some light on CLient Object Model, the code you referred is for server object.
