C# CAML query to sharepoint returns all items in the list (instead of only ones that mach query value)

Question

I have the following code in my app to pull details from a sharepoint list.

            string siteUrl = "http://SHAREPOINTURL";

        ClientContext clientContext = new ClientContext(siteUrl);
        clientContext.Credentials = new NetworkCredential("UN", "PW", "DOMAIN");
        SP.List oList = clientContext.Web.Lists.GetByTitle("Licences");

        CamlQuery camlQuery = new CamlQuery();
        camlQuery.ViewXml = "<Where><Eq><FieldRef Name='Account' /><Value Type='Text'>123456</Value></Eq></Where>";

        ListItemCollection collListItem = oList.GetItems(camlQuery);
        clientContext.Load(collListItem);
        clientContext.ExecuteQuery();

        Console.WriteLine("Filtered List: " + collListItem.Count.ToString() + "\n");
        foreach (ListItem oListItem in collListItem)
        {
            Console.WriteLine("Account: {0} \nLicence: {1} \nMAC: {2}\n", oListItem["Account"], oListItem["Licence"], oListItem["MAC"]);
        }

In the sharepoint list I have created multiple test items but every time I run the above code all items in the list are returned regardless of what I use for the camlQuery.

Can anyone let me know where I'm going wrong with this pretty new to C# and never touched sharepoint before this.

Edit1: updated with advice from below.

Edit2: simplified the code but still getting the same problem.

Answer 1

If you want to return the filtered items, in your case is returning all the items, correct? if yes, this problem is in CAMLQuery ...

I have read a small documentation(link below):

Microsoft MSDN

And I noticed the formatting ViewXml:

camlQuery.ViewXml = "<Where><Eq><FieldRef Name='Account' /><Value Type='Text'>123456</Value></Eq></Where>"

try with this code:

camlQuery.ViewXml = "<View><Query><Where><Eq><FieldRef Name='Account' /><Value Type='Text'>123456</Value></Eq></Where></Query></View>"

I have working using with caml.

some syntax to reflect:

camlquery.query = "<query> ..... </query>";
camlquery.ViewXml = "<view> ..... </view>";

SORRY MY BAD ENGLISH :S
