c# - Join Dictionary<int, string> and List<MyClass> error (type arguments for method cannot be inferred from the usage) -

-

i´m trying join dictionary<int, string> , list<myclass> throws error

"type arguments method cannot inferred usage".

but seems me arguments defined...

class row {         public string name { get; set; }         public string[] data { get; set; } }  dictionary<int, string> devices = new dictionary<int,string>(); list<row> rows = new list<row>();  rows = rows.join(devices, row => row.data[0], device => device.key, (row, device) => { row.data[1] = device.value; return row; }).tolist();

row row, device pair<int,string>, device.key int, , device.value k. problem? know must silly thing, i´m stuck error.

row.data[0] string, device.key integer, key types don't match.
