嗨我正尝试使用SQL表中的数据在线连接并发布日历，并收到以下异常，请指教。同样的代码可以正常工作，只需稍微修改一下就可以使用Sharepoint服务器我已经添加了sharepointonline进行身份验证，但是由于错误而失败。使用Powershell连接到sharepoint oniline：无法找到类型为Microsoft.SharePoint.Client.ClientContext的适当构造函数
[System.Reflection.Assembly]::LoadFile ("C:\MOSSLibrary\Microsoft.SharePoint.Client.dll") | Out-Null
[System.Reflection.Assembly]::LoadFile("C:\MOSSLibrary\Microsoft.SharePoint.Client.Runtime.dll") | Out-Null
$username = "XXXXXX"
$url = "XXXXXX"
$pass= cat C:\text.txt | ConvertTo-SecureString
$Context = New-Object Microsoft.SharePoint.Client.ClientContext($siteUrl)
$Creds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username,$Pass)
$Context.Credentials = $Creds
$web = $Context.Web
$Context.Load($web)
$Context.Load($splist)
$splist = $Context.web.Lists.GetByTitle("XXXX")
$ItemCreateInfo = New-Object Microsoft.SharePoint.Client.ListItemCreationInformation
####Some Data coming from SQL Server DB into $table########
$table = $result.Tables[0];
foreach ($row in $table)
{
Write-Host $row.Item("changetitle") $row.Item("status");
$Item1 = $splist.AddItem($ItemCreateInfo)
$Item1["Title"] = "test"
Write-host $date
$Item1.Update()
$Context.ExecuteQuery()
}
异常
