Mongodb 使用PowerShell插入新的Mongo行

我有一个PowerShell脚本，整天都在困扰我。我终于到了可以得到一个收藏的地步，但是我得到了一个我无法理解的错误

function Get-MongoDBCollection {
  Param(
    $database,
    $CollectionName,
    $settings = $null, #[MongoDB.Driver.MongoCollectionSetting]
    $returnType = [PSOBJECT]
  )
  $method = $database.GetType().GetMethod('GetCollection')
  $gericMethod = $method.MakeGenericMethod($returnType)
  $gericMethod.Invoke($database,[object[]]($CollectionName,$settings))
}

$dbName = "MyDatabaseName"
$collectionName = "MyCollectionName"

try {
   add-type -path 'C:\Program Files\MongoDB\Drivers\System.Runtime.InteropServices.RuntimeInformation.4.0.0\lib\net45\System.Runtime.InteropServices.RuntimeInformation.dll'
  Add-Type -Path "C:\Program Files\MongoDB\Drivers\MongoDB.Bson.2.6.0\lib\net45\MongoDB.Bson.dll"

   add-type -path "C:\Program Files\MongoDB\Drivers\DnsClient.1.0.7\lib\net45\DnsClient.dll";
   Add-Type -path "C:\Program Files\MongoDB\Drivers\MongoDB.Driver.Core.2.6.0\lib\net45\MongoDb.Driver.Core.dll"
   Add-Type -Path "C:\Program Files\MongoDB\Drivers\MongoDB.Driver.2.6.0\lib\net45\MongoDB.Driver.dll"
}
catch {
  $_;
  $_.Exception.LoaderExceptions

}

$connectionString = "mongodb://localhost:27018";
$mongoClient = new-object MongoDb.Driver.MongoClient($connectionString);

$mongoDatabase = $mongoclient.GetDatabase($dbName)
$mongoDatabase.GetCollection($collectionname)

$collection = Get-MongoDBCollection $mongodatabase "SharePoint" -returnType ([MongoDB.Bson.BsonDocument]);

$datafile = Get-Content -Raw -Path "D:\datafiles\86fba866-77ed-4f40-4637-08d57d2e25b4.json" #`| ConvertFrom-Json
[MongoDB.Bson.BsonDocument] $doc = [MongoDB.Bson.BsonDocument]::Parse($datafile);
$x = $collection.InsertOne($doc)

脚本获取包含JSON字符串的文件的内容，并将其转换为BsonDocument，然后尝试插入它。我得到以下错误

Argument types do not match
At line:1 char:1
+ $collection.InsertOneAsync($doc)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  + CategoryInfo          : OperationStopped: (:) [], ArgumentException
  + FullyQualifiedErrorId : System.ArgumentException

---

我做错了什么？

这是一块硬饼干！基本上，powershell不支持泛型。。它支持他们，但以一种复杂而难以理解的方式

几天前，我在另一篇堆栈溢出文章中发现了这个代码段，但现在找不到。一开始这是一次令人不快的搜索/跋涉。原著作者的片段，我希望我能给予适当的信任，如下所示：

###
# Usage:
# $Collection = Get-MongoDBCollection $database 'collectionName'
#  or
# $Collection = Get-MongoDBCollection $database 'collectionName' -returnType  ([MongoDB.Bson.BsonDocument])
function Get-MongoDBCollection {
   Param(
    $database,
    $CollectionName,
    $settings = $null, #[MongoDB.Driver.MongoCollectionSetting]
    $returnType = [PSOBJECT]
  )
  $method = $database.GetType().GetMethod('GetCollection')
  $gericMethod = $method.MakeGenericMethod($returnType)
  $gericMethod.Invoke($database,[object[]]($CollectionName,$settings))
}

下面是我在上下文中的完整用法。我还必须自己加载DnsClient.dll依赖项。在整个过程中，按照惯例，powershell模块未能提供有用的错误

PS：这是业余的powershell，只使用.PS，因为我需要连接Office365！没有最佳实践的承诺
