推荐答案

其实有几件事情，当你添加一列在浏览器列表，发生：

There are actually several things that happen when you add a column to a list in the browser:

• 字段添加到列表


• 字段添加到列表内容类型


• 字段添加到默认视图

当您使用代码添加一列，你可能只修改名单，但没有内容类型（定义新/编辑表单）或视图（定义列表视图）

When you add a column using code, you may only be modifying the list, but not the content type (which defines new/edit forms) or the view (which defines list views)

                var field = list.Fields[fieldName];

                var ctype = list.ContentTypes[contentTypeId];
                var fieldref = new SPFieldLink(field);
                ctype.FieldLinks.Add(fieldref);
                ctype.Update();

                var view = list.Views[viewName];
                view.ViewFields.Add(field);
                view.Update();
