Question

我正在尝试按代码连接内容类型，（不要问为什么），哈哈。该功能正常，新列可以很好地添加到视图中。

出于某种原因，在NEW或Edit表单中，不存在新的Field Source Name。当我进入列表设置，高级时，它显示管理内容类型=否，但我在代码上将其设置为是。

我没有想法。

Answer 1

sourceList.ContentTypesEnabled = true; 
sourceContentType.Update(true); 

//Update the sourceList here this before you add the CT 
sourceList.ContentTypes.Add(sourceContentType);

Answer 2

问题在于，当我创建内容类型时，它基于Document而不是item，因此我将该部分更改为this并且它有效。

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

按代码创建内容类型。新表格为空
