PowerShell上传整个目录下的文件到SharePoint的二级目录（文件大于2M）

之前的脚本上传大于2M的文件会失败，需要使用FileStream函数来进行上传。

```csharp
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12

#Specify tenant admin and site URL
$User = "jz@one.com"
$Password = "password@2022"  | ConvertTo-SecureString -AsPlainText -Force
$SiteURL = "https://one.sharepoint.com/sites/Test/"
$Folder = "D:\Test\files\"
$DocLibName = "ERetail"
$FolderName  = "OldReport/report(SN)"

#Add references to SharePoint client assemblies
Add-Type -Path "C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SharePoint.Client\v4.0_16.0.0.0__71e9bce111e9429c\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SharePoint.Client.Runtime\v4.0_16.0.0.0__71e9bce111e9429c\Microsoft.SharePoint.Client.Runtime.dll"

#Bind to site collection
$Context = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Creds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($User,$Password)
$Context.Credentials = $Creds

#Retrieve list
$List = $Context.Web.Lists.GetByTitle($DocLibName)
#$List = $Context.Web.Lists.GetByTitle("Certificates")
$Context.Load($List.RootFolder)
$Context.ExecuteQuery()

$TargetFolder = $Context.Web.GetFolderByServerRelativeUrl($List.RootFolder.ServerRelativeUrl + "/" + $FolderName);

#Upload file(s)
Foreach ($File in (dir $Folder -File))
{
    $FileStream = New-Object IO.FileStream($File.FullName,[System.IO.FileMode]::Open)
    $FileCreationInfo = New-Object Microsoft.SharePoint.Client.FileCreationInformation
    $FileCreationInfo.Overwrite = $true
    $FileCreationInfo.ContentStream = $FileStream
    $FileCreationInfo.URL = $File.Name
    $UploadFile = $TargetFolder.Files.Add($FileCreationInfo)
    $Context.Load($UploadFile)
    $Context.ExecuteQuery()
}

```
