本文将介绍如何快速隐藏列表或文档库的新建文件夹命令项：

操作环境：Windows Server 2008 r2+ SharePoint 2010

1.通过Feature来实现

1.1如果你想针对列表来隐藏新建文件夹命令，Feature代码如下：

 <CustomAction Id="Remove.ListItem.NewFolder" Location="CommandUI.Ribbon">     
  <CommandUIExtension>       
  <CommandUIDefinitions>         
  <CommandUIDefinition Location="Ribbon.ListItem.New.NewFolder" />       
  </CommandUIDefinitions>     
  </CommandUIExtension> 
</CustomAction>

1.2如果你想针对文档库来隐藏新建文件夹命令，Feature如下：

<CustomAction Id="Remove.Document.NewFolderButton" Location="CommandUI.Ribbon" RegistrationId="0x0101" RegistrationType="ContentType"> 
<CommandUIExtension>       
<CommandUIDefinitions> 
<CommandUIDefinition Location="Ribbon.Documents.New.NewFolder" />       
</CommandUIDefinitions>     
</CommandUIExtension> 
</CustomAction>

1.3如果你想同时针对列表和文档库来隐藏新建文件夹命令，Feature如下：

<?xmlversion="1.0"encoding="utf-8"?>
<Elementsxmlns="http://schemas.microsoft.com/sharepoint/">
  <CustomAction
    Id="Remove.ListItem.NewFolder"
    Location="CommandUI.Ribbon">
    <CommandUIExtension>
      <CommandUIDefinitions>
        <CommandUIDefinition
          Location="Ribbon.ListItem.New.NewFolder"/> 
      </CommandUIDefinitions>
    </CommandUIExtension>
  </CustomAction>
  <CustomAction
    Id="Remove.Document.NewFolderButton"
    Location="CommandUI.Ribbon"RegistrationId="0x0101" 
    RegistrationType="ContentType">
    <CommandUIExtension>
      <CommandUIDefinitions>
        <CommandUIDefinition
          Location="Ribbon.Documents.New.NewFolder"/> 
      </CommandUIDefinitions>
    </CommandUIExtension>
  </CustomAction>
</Elements>

2.通过c#代码来实现：

无论是列表还是文档库都有一个.EnableFolderCreation 属性，它可以控制是否启用新建文件夹命令。

SPSite spSite = new SPSite("http://sp2010vm");
            foreach (SPWeb spWeb in spSite.AllWebs)
            {
                spWeb.AllowUnsafeUpdates = true;

                SPListCollection lists = spWeb.Lists;
                for (int i = 0; i < lists.Count; i++)
                {
                    if (lists[i] is SPDocumentLibrary)
                    {
                        if (((SPDocumentLibrary)lists[i]).IsCatalog == false)
                        {
                            SPDocumentLibrary spList = (SPDocumentLibrary)lists[i];
                            if (spList.Title == "Classified Documents")
                            {
                                ////Update the list properties
                                spList.EnableFolderCreation = false;
                                spList.Update();
                            }
                        }
                    }
                }

                spWeb.AllowUnsafeUpdates = false;
                spWeb.Dispose();                   
            }

            spSite.Dispose();

3.库设置--高级设置-- 是否提供“新建文件夹”命令
