SPFieldLookup "Add a column to show each of these additional fields" 以编程方式

Question

Additional fields

我想在从 SPField 进行 SPFieldLookup 转换时获取此列表，并另外编辑以显示更多字段。有谁之前经历过这个吗？请帮帮我。

foreach (SPField oSPFieldV2 in olistsubGoc.Fields)
                    {
                        if (oSPFieldV2.StaticName.Contains(oField.StaticName + "_x003a_"))
                        {
                            try
                            {
                                if (olistsub.Fields.TryGetFieldByStaticName(oSPFieldV2.StaticName) == null)
                                {
                                    SPField tmep = olistsub.Fields.TryGetFieldByStaticName(oField.StaticName);
                                    string depLookUp = olistsub.Fields.AddDependentLookup(oSPFieldV2.StaticName, tmep.Id);
                                    SPFieldLookup fieldDepLookup = (SPFieldLookup)olistsub.Fields.GetFieldByInternalName(depLookUp);
                                    fieldDepLookup.LookupField = oSPFieldV2.StaticName.Replace(oField.StaticName + "_x003a_", "");
                                    fieldDepLookup.Update();
                                }
                            }
                            catch (Exception ex)
                            {
                            }
                        }
                    }

这是我找到的问题的解决方案。
