Question

当我尝试按代码创建内容类型和列表时，新表单我看不到新字段。我不知道还有什么要检查，我在其他博客文章的基础上构建了这段代码。

 public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            Logger.LogDebug("NLSponsoringListSalesNumbersEventReceiver", "FeatureActivated(SPFeatureReceiverProperties properties)", "BEGIN");

                AddSourcesList(currentWeb);



     private void AddSourcesList(SPWeb currentWeb)

问题是因为默认情况下添加的内容类型是基于Document而不是类型。

我把那部分改成了这个

  SPContentType itemCtype = currentWeb.AvailableContentTypes[SPBuiltInContentTypeId.Item];
                SPContentType sourceContentType = new SPContentType(itemCtype, currentWeb.ContentTypes, SponsoringCommon.Constants.CONTENTTYPES_SOURCES_NAME);
                sourceContentType = currentWeb.ContentTypes.Add(sourceContentType);

然后它运作良好
