I have a SPListItem, with different fields (string, lookup, etc), that I have to iterate them and do different actions depending of the type.

How can I detect if value is type String or type Lookup?

  value = spListItem["nameField"];  // is string or lookup?

You can simply use the C# is operation. Ie.

if (value is SPFieldLookupValue) {}

try this

string tipoCampo = itemCollection.Fields[ColumnsAssignation.ComboText].TypeAsString;
if (tipoCampo == "Lookup") {}
