我有以下 csom 脚本来更新站点列并下推更改：

Add-Type -Path "Libraries\Microsoft.SharePoint.Client.dll" 
Add-Type -Path "Libraries\Microsoft.SharePoint.Client.Runtime.dll" 

$webUrl = "enter_url_here" 
$username = "enter_username_here"
$password = "enter_password_here"
$securePass = ConvertTo-SecureString $password -AsPlainText -Force

$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($webUrl)
$ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $securePass)

#Add description to the "Other category" field
$fieldTitle = "Other category"
$fieldDesc = "Search for an existing name before adding new entries"
$field = $ctx.Site.RootWeb.Fields.GetByInternalNameOrTitle($fieldTitle)
$field.Description = $fieldDesc
$field.UpdateAndPushChanges($true)

#Add description to the "Initiator location" field
$field2Title = "Initiator location"
$field2 = $ctx.Site.RootWeb.Fields.GetByInternalNameOrTitle($field2Title)
$field2.Description = $fieldDesc
$field2.UpdateAndPushChanges($true)

#Setting the "Main-category" field as required/mandatory
$field3Title = "Main-category"
$field3 = $ctx.Site.RootWeb.Fields.GetByInternalNameOrTitle($field3Title)
$field3.Required = $true
$field3.UpdateAndPushChanges($true)

$ctx.ExecuteQuery()

上述字段/列都是称为“主文档”的站点内容类型的一部分。

到目前为止，这工作正常，但是对于“主类别”字段，如何在内容类型级别将其设置为“必需”？目前这仅在网站栏级别设置，实现这一目标的最简单方法是什么？

非常感谢。

使用ContentType.FieldLinks 属性获取内容类型中的字段引用，然后使用FieldLink.Required 属性设置指定字段是否需要值的值。

例子

如何Required通过 Content Type 为字段设置属性：

$ct = $ctx.Web.ContentTypes.GetById($ctId) #get Content Type 
$fieldLink = $ct.FieldLinks.GetById($fieldId) #get Field Link
$fieldLink.Required = $true
$ct.Update($true)
$ctx.ExecuteQuery()
