PowerShell与MongoDB C＃驱动程序的方法不兼容？ [英] PowerShell not compatible with MongoDB C# Driver's Methods?

问题描述

由C＃泛型导致的最新MongoDB驱动程序问题：

 无法找到GetCollection的重载和参数计数：1。 
  

我大概可以使用其他的GetCollection方法，而不使用泛型，但我不知道如何。 p>

答案公布后指出了一些很好的信息，但不幸的是，提供的代码与我已经尝试过的代码相同，并且不起作用。

以下是我想要做的：

我想使用PowerShell创建一些文档。
我现在面临的问题似乎是GetCollection无法正常工作。我认为这与Powershell中对泛型的支持不足有关。无论如何，我发现一些CmdLets运行通用方法。但我认为这会使代码太复杂。有没有办法解决这个问题？

我看到有其他GetCollection方法不基于C＃泛型，但我不明白如何使用他们在PowerShell中。

Powershell异常：无法找到GetCollection的重载和参数计数：1

 ＃Mongo DB驱动程序
 Add-Type -Path'CSharpDriver-2.0.1\MongoDB.Bson。 dll'
 Add-Type -Path'CSharpDriver-2.0.1\MongoDB.Driver.dll'
 
＃连接到MongoDB 
 $ connectionString =mongodb：// localhost ：27018
 $ db =TestDB
 $ collection =Test
 
 
函数Get-MongoDBCollection（$ connectionString，$ db，$ collection）
 {
 $ mongoClient =新物体MongoDB.Driver.MongoClient（$的connectionString）
 $ mongoDatabase = $ mongoClient.GetDatabase（$分贝）
 $ mongoCollection = $ mongoDatabase.GetCollection（ $ collection）
 return $ mongoCollection 
} 
 
 
＃连接到MongoDB并获得集合
 $ mongoCollection = Get-MongoDBCollection $ connectionString $ db $ collection 
  

上面列出的代码是从以前的SO问题中复制（并稍微更改）： Powershell Mongodb身份验证

任何建议如何做到这一点？我假定SO中列出的代码是基于较早的驱动程序版本。我认为这就是为什么它不再工作。

PowerShell控制台上的完全执行：

 无法找到GetCollection的重载和参数计数：1。 
在F：\PowerShell\CreateDB.ps1：31 char：3 
 + $ mongoCollection = $ mongoDatabase.GetCollection（$ collection）
 + ~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 〜
 + CategoryInfo：NotSpecified：（:) []，MethodException 
 + FullyQualifiedErrorId：MethodCountCouldNotFindBest 
  

解决方案

我希望这仍然可以得到一些帮助，这对我来说是最新的C＃驱动程序和当前的MongoDB RC-4。

 函数Get-MongoDBCollection {
 Param（
 $ database，
 $ CollectionName，
 $ settings = $ null， ＃[MongoDB.Driver.MongoCollectionSetting] 
 $返回类型= [PSOBJECT] 
）
 $方法= $ database.GetType（）。GetMethod（ 'GetCollection'）
 $ gericMethod = $ method.MakeGenericMethod（$ returnType）
 $ gericMethod.Invoke（$ database，[object []]（$ CollectionName，$ settings））
} 
 $ Collection = Get-MongoDBCollection $ database'test'
＃or 
 $ Collection = Get-MongoDBCollection $ database'test'-returnType（[MongoDB.Bson.BsonDocument]）
  

Problem with latest MongoDB Driver caused by the C# Generics:

Cannot find an overload for "GetCollection" and the argument count: "1".

I could probably use other GetCollection methods without the generics, but I do not know how exactly.

The answer posted further down points out some good information but unfortunately the provided code was the same than I already tried and it is not working.

Here is what I would like to do:

I want to work with PowerShell to create a few documents. The issue I am facing now seems that "GetCollection" does not work properly. I think it has to do with the lack of support for generics in Powershell. Anyway I found some CmdLets to run generic methods. But I think this will make the code too complicated. Is there a way to get around this issue?

I saw that there are other GetCollection methods which are not based on C# Generics, but I do not understand yet how to use them in PowerShell.

Powershell Exception: Cannot find an overload for "GetCollection" and the argument count: "1"

# Mongo DB driver
Add-Type -Path 'CSharpDriver-2.0.1\MongoDB.Bson.dll'
Add-Type -Path 'CSharpDriver-2.0.1\MongoDB.Driver.dll'

# Conncetion to MongoDB
$connectionString = "mongodb://localhost:27018"
$db =  "TestDB"
$collection =  "Test"


function Get-MongoDBCollection ($connectionString, $db, $collection)
{
   $mongoClient = New-Object MongoDB.Driver.MongoClient($connectionString)
   $mongoDatabase = $mongoClient.GetDatabase($db)
   $mongoCollection = $mongoDatabase.GetCollection($collection)
   return $mongoCollection
}


# Connect to MongoDB and get collection
$mongoCollection = Get-MongoDBCollection $connectionString $db $collection

The code listed above is copied (and slightly changed) from an earlier SO question: Powershell Mongodb Authentication

Any suggestion how this can be done? I assume that the code listed in the SO is based on an earlier driver version. I think that is why it is not working any more.

Full Exeption on PowerShell console:

Cannot find an overload for "GetCollection" and the argument count: "1".

解决方案

I hope this can still be of some help, this worked for me with the latest C# Driver and the current MongoDB RC-4.

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))
}
$Collection = Get-MongoDBCollection $database 'test'
# or 
$Collection = Get-MongoDBCollection $database 'test' -returnType  ([MongoDB.Bson.BsonDocument])
