对于SharePoint中已经是Record的Item，我们想要修改他的属性，这在UI界面是无法完成的：
这时需要通过Records.BypassLocks API来完成。设计一个tool，利用Records.BypassLocks API来修改Recorded Items的属性(这里拿Title举例)，界面如下：
代码如下：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using Microsoft.SharePoint; using Microsoft.SharePoint.Utilities; //Assembly: Microsoft.Office.Policy (in Microsoft.Office.Policy.dll) using Microsoft.Office.RecordsManagement.RecordsRepository; using Microsoft.SharePoint.Publishing; namespace BypassLocksTestTool { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void test_button_Click(object sender, EventArgs e) { try { SPSecurity.RunWithElevatedPrivileges(delegate () { SPSite site = new SPSite(siteURL_textBox.Text); SPWeb web = site.RootWeb; SPList list = web.Lists[listTitle_textBox.Text]; SPListItem item = list.Items[0]; Records.BypassLocks(item, delegate (SPListItem spListItem) { //Do your stuff here. item["Title"] = itemTitle_textBox.Text; item.Update(); if (list.Items[0].Title == itemTitle_textBox.Text) { testResult_richTextBox.Text = "Test result is passed! Now the first item's title is: " + list.Items[0].Title; testResult_richTextBox.Select(0, testResult_richTextBox.Text.Length); testResult_richTextBox.SelectionColor = Color.Green; } else { testResult_richTextBox.Text = "Test result is failed!"; testResult_richTextBox.Select(0, testResult_richTextBox.Text.Length); testResult_richTextBox.SelectionColor = Color.Red; } }); }); } catch (Exception ex) { testResult_richTextBox.Text = ex.ToString(); } } } }
点击Test按钮进行测试，测试结果会回显到界面，如果Title的value完成了修改，则算测试通过；否则算测试失败。
测试通过后，我们去SharePoint中查看Item的属性，结果和我们预期的一样，对应Item的Title属性值已经变为“SuperTylan”：
这就是对于Records.BypassLocks API的使用与测试，它让我们修改locked recorded item的属性与内容成为可能。
