以編程方式創建新DocumentSet [SharePoint]時發生異常

Question

當我嘗試使用Visual Studio aspx頁面在SharePoint 2016中創建新文檔集時，出現異常。 例外：對象引用未設置為對象的實例。

請幫忙。

網站示例網址： http：//dev-office.my-site.local

列表（庫）名稱：TestSolution

該庫已經存在，文檔集可用，並且已在該庫中手動創建。 ApplicationPage1.aspx用作默認表單，用於為當前庫創建新的DocumentSet。

下面的代碼：

ApplicationPage1.aspx共有四個控件：兩個TextBox（名稱，描述），一個Button和用於顯示錯誤的標簽。 在OnClick action =“ createDocSetButton_Click”按鈕上，這將創建一個新的文檔集。

    <%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
<%@ Import Namespace="Microsoft.SharePoint.ApplicationPages" %>
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=16.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<asp:Content ID="PageHead" ContentPlaceHolderID="PlaceHolderAdditionalPageHead" runat="server">

</asp:Content>

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">

    <p>
        Name: <asp:TextBox ID="nameTextbox" runat="server"></asp:TextBox>
    </p>
    <p>
        Description: <asp:TextBox ID="descriptionTextbox" runat="server"></asp:TextBox>
    </p>

    <asp:Button ID="createDocSetButton" OnClick="createDocSetButton_Click" runat="server" Text="Create Document Set" />
    <asp:Label ID="resultLabel" runat="server" Text=""></asp:Label>  

</asp:Content>

<asp:Content ID="PageTitle" ContentPlaceHolderID="PlaceHolderPageTitle" runat="server">

</asp:Content>

<asp:Content ID="PageTitleInTitleArea" ContentPlaceHolderID="PlaceHolderPageTitleInTitleArea" runat="server" >

</asp:Content>

ApplicationPage1.aspx.cs它具有綁定到按鈕並創建文檔集的簡單方法。

using System;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using System.Collections;
using System.Collections.Generic;
using Microsoft.Office.DocumentManagement.DocumentSets;
using System.IO;
using System.ComponentModel;
using System.Web;
using Microsoft.SharePoint.Client;


namespace SharePointProject17.Layouts.SharePointProject17
{
    public partial class ApplicationPage1 : LayoutsPageBase
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            nameTextbox.Focus();
    }

    protected void createDocSetButton_Click(object sender, EventArgs e)
    {
        //Get the Shared Documents document library
        SPWeb currentWeb = SPContext.Current.Web;
        SPList sharedDocsLib = currentWeb.Lists["TestSolution"];
        //You can use a hashtable to populate properties of the document set
        Hashtable docsetProperties = new Hashtable();
        docsetProperties.Add("Name", nameTextbox.Text);
        docsetProperties.Add("Description", descriptionTextbox.Text);
        //Create the document set
        try
        {
            DocumentSet newDocSet = DocumentSet.Create(sharedDocsLib.RootFolder,
                nameTextbox.Text, sharedDocsLib.ContentTypes["Document Set"].Id,
            docsetProperties, true);
            resultLabel.Text = "Document set created";
        }
        catch (Exception ex)
        {
            resultLabel.Text = "Error: " + ex.Message;
        }            

    }

}
}
