Example of using the 10gen MongoDB CSharp driver in powershell.

MongoTest.ps1

# We assume that the driver is installed via the MSI.

[string] $mongoDriverPath;
# Check to see if we are running the 64 bit version of Powershell. 
# See http://stackoverflow.com/questions/2897569/visual-studio-deployment-project-error-when-writing-to-registry
if ([intptr]::size -eq 8) {
    $mongoDriverPath = (Get-ItemProperty "HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v3.5\AssemblyFoldersEx\MongoDB CSharpDriver 1.0").'(default)';
}
else {
    $mongoDriverPath = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\.NETFramework\v3.5\AssemblyFoldersEx\MongoDB CSharpDriver 1.0").'(default)';
}
Add-Type -Path "$($mongoDriverPath)\MongoDB.Bson.dll";

# The [ordered] only works in PowerShell 3.0 an later.
[MongoDB.Bson.BsonDocument] $doc = [ordered]@{
    "_id"= [MongoDB.Bson.ObjectId]::GenerateNewId();
    "FirstName"= "Justin";
    "LastName"= "Dearing";
    "PhoneNumbers"= [MongoDB.Bson.BsonDocument] [ordered]@{
        'Home'= '718-555-1212';
        'Mobile'= '646-555-1212';
    };
};

Add-Type -Path "$($mongoDriverPath)\MongoDB.Driver.dll";

$db = [MongoDB.Driver.MongoDatabase]::Create('mongodb://localhost/powershell');
$collection = $db['example1'];
Write-Host "Insert";
$collection.Insert($doc);
$collection.FindOneById($doc['_id']);

$updates = @{'email'= '[email protected]'};
$query = @{"_id"= $doc['_id']}

Write-Host "Update";
$collection.Update([MongoDB.Driver.QueryDocument]$query, [MongoDb.Driver.UpdateDocument]$updates);
$collection.FindOneById($doc['_id']);

Write-Host "Delete";
$collection.Remove([MongoDB.Driver.QueryDocument]$query);
$collection.FindOneById($doc['_id']);

Thanks for posting this. How would you query with multiple values, like by First name and Home phone number?

This example no longer works, I have tested it on Powershell x86 and x64 bit, with the installation of # drive drive 1.9 last one with msi installed. In that case it does not find any registry settings.

With just trying to reference the same to the local dll files I get the message that it's dependencies are missing. for both the dlls. I have tested the same on Powershell 3.0 and 4.0 x32 and x64 bit. With driver versions 1.9, 1.10 and 2.0. Any suggestions.
