Making a request for data with C#.NET

I am working on creating a small tool to work with the XML-RPC service for a hosted Odoo instance. I have managed to create the connection and authenticate, but having difficulties creating a request properly. Seems that I can not pick the correct datatype.

The php code looks like this:

$models->execute_kw($db, $uid, $password,

    'res.partner', 'search_read',
    array(array(array('is_company', '=', true),
                array('customer', '=', true))),
    array('fields'=>array('name', 'country_id', 'comment'), 'limit'=>5));

My C# code to create the parameter array looks like this:

            //search criterias
            object[] c1 = new object[] { "name", "=", "Lunderskov Boldklub" };

            //list of all criterias
            object[] criterias = new object[] { c1 };

            //fields defs

            object[] defs = { new object[] { "fields", new object[] { "name", "country_id", "comment" } }, new object[] {"limit", 5}}; 

            object[] parms = new object[] { criterias, defs };

Now.. the Odoo response is:

<?xml version='1.0'?>
<value><string>unhashable type: 'list'</string></value>
<value><string>Traceback (most recent call last):
  File "/home/odoo/src/odoo/8.0/openerp/service/wsgi_server.py", line 75, in xmlrpc_return
    result = openerp.http.dispatch_rpc(service, method, params)
  File "/home/odoo/src/odoo/8.0/openerp/http.py", line 108, in dispatch_rpc
    result = dispatch(method, params)
  File "/home/odoo/src/odoo/8.0/openerp/service/model.py", line 37, in dispatch
    res = fn(db, uid, *params)
  File "/home/odoo/src/odoo/8.0/openerp/service/model.py", line 162, in execute_kw
    return execute(db, uid, obj, method, *args, **kw or {})
  File "/home/odoo/src/odoo/8.0/openerp/service/model.py", line 113, in wrapper
    return f(dbname, *args, **kwargs)
  File "/home/odoo/src/odoo/8.0/openerp/service/model.py", line 170, in execute
    res = execute_cr(cr, uid, obj, method, *args, **kw)
  File "/home/odoo/src/odoo/8.0/openerp/service/model.py", line 159, in execute_cr
    return getattr(object, method)(cr, uid, *args, **kw)
  File "/home/odoo/src/odoo/8.0/openerp/api.py", line 237, in wrapper
    return old_api(self, *args, **kwargs)
  File "/home/odoo/src/odoo/8.0/openerp/models.py", line 5061, in search_read
    result = self.read(cr, uid, record_ids, fields, context=read_ctx)
  File "/home/odoo/src/odoo/8.0/openerp/api.py", line 237, in wrapper
    return old_api(self, *args, **kwargs)
  File "/home/odoo/src/odoo/8.0/openerp/models.py", line 3078, in read
    result = BaseModel.read(records, fields, load=load)
  File "/home/odoo/src/odoo/8.0/openerp/api.py", line 235, in wrapper
    return new_api(self, *args, **kwargs)
  File "/home/odoo/src/odoo/8.0/openerp/models.py", line 3102, in read
    if name in self._columns:
TypeError: unhashable type: 'list'

So.. how should I create the last part of the request?


I solved the problem myself finally. This code works..


            XmlRpcStruct d = new XmlRpcStruct();
            d.Add("fields", new object[] { "name", "country_id", "comment"});
            d.Add("limit", 5);


Thanks for posting the solution to your own question so that the next person might benefit from your solution.
