Created documents are used by Add-MdbcData and Export-MdbcData. These cmdlets also have parameters Id, NewId, Convert, Property for making documents from input objects. Thus, in some cases intermediate use of New-MdbcData is not needed. Mdbc.Dictionary Result documents are returned as Mdbc.Dictionary objects. Mdbc.Dictionary holds an underlying BsonDocument (Document()) and implements IDictionary. It works as a hashtable where keys are case sensitive strings and input and output values are convenient .NET types instead of underlying BsonValues. Main features: Useful members: $dictionary.Count $dictionary.Contains('key') $dictionary.Add('key', 'value') $dictionary.Remove('key') $dictionary.Clear() Setting values: $dictionary['key'] = ... $dictionary.key = ... Getting values: .. = $dictionary['key'] .. = $dictionary.key NOTE: On getting values the form "$dictionary.key" fails in strict mode (see Set-StrictMode) if the "key" is missing. The form "$dictionary['key'] is safe, it returns null for a missing key. Use Contains() in order to check existence of a key for sure.</maml:para> </maml:description> <command:syntax> <command:syntaxItem> <maml:name>New-MdbcData</maml:name> <command:parameter required="false" position="named" > <maml:name>Value</maml:name> <command:parameterValue required="true">PSObject</command:parameterValue> </command:parameter> </command:syntaxItem> <command:syntaxItem> <maml:name>New-MdbcData</maml:name> <command:parameter required="false" position="1" > <maml:name>InputObject</maml:name> <command:parameterValue required="true">PSObject</command:parameterValue> </command:parameter> <command:parameter required="false" position="named" > <maml:name>Convert</maml:name> <command:parameterValue required="true">ScriptBlock</command:parameterValue> </command:parameter> <command:parameter required="false" position="named" > <maml:name>Id</maml:name> <command:parameterValue required="true">PSObject</command:parameterValue> </command:parameter> <command:parameter required="false" position="named" > <maml:name>Property</maml:name> <command:parameterValue required="true">Object[]</command:parameterValue> </command:parameter> <command:parameter required="false" position="named" > <maml:name>NewId</maml:name> </command:parameter> </command:syntaxItem> </command:syntax> <command:parameters> <command:parameter required="false" pipelineInput="true (ByValue)" position="1" > <maml:name>InputObject</maml:name> <maml:description> <maml:para>.NET object to be converted to Mdbc.Dictionary, PowerShell friendly wrapper of BsonDocument.

Converters should be used sparingly, normally with unknown or varying data.

Hashtables @{Key=Value} define renamed and calculated fields. The key is a new document field name. The value is either a string (input object property name) or a script block (field value calculated from the input object $_). 3. Hashtables @{Name=...; Expression=...} or @{Label=...; Expression=...} are similar but use the same convention as the parameter Property of Select-Object.

Cmdlets and helper types do not need BsonValue's, they convert everything themselves. But BsonValue's may be needed for calling driver methods directly. Containers: [IDictionary] is converted to BsonDocument. [IEnumerable] is converted to BsonArray. Primitives: [bool] is converted to BsonBoolean. [DateTime] is converted to BsonDateTime. [double] is converted to BsonDouble. [Guid] is converted to BsonBinaryData (and retrieved back as [Guid]). [int] is converted to BsonInt32. [long] is converted to BsonInt64. [string] is converted to BsonString. If a primitive type is known than it is much more effective to create it directly than by this cmdlet, e.g. for a string: [MongoDB.Bson.BsonString]'Some text'</maml:para> </maml:description> </command:parameter> </command:parameters> <command:inputTypes> <command:inputType> <dev:type> <maml:name>$null</maml:name> </dev:type> <maml:description> <maml:para>Null is converted to an empty document by New-MdbcData and ignored by Add-MdbcData and Export-MdbcData.</maml:para> </maml:description> </command:inputType> <command:inputType> <dev:type> <maml:name>[Mdbc.Dictionary]</maml:name> </dev:type> <maml:description> <maml:para>Objects created by New-MdbcData or obtained by Get-MdbcData or Import-MdbcData.

Shortcuts, either enum values or strings: Default Default output, Mdbc.Dictionary with underlying BsonDocument. Lazy Mdbc.LazyDictionary with underlying LazyBsonDocument. Call Dispose() after use. Raw Mdbc.RawDictionary with underlying RawBsonDocument. Read only. Call Dispose() after use. PS PowerShell custom object. By default result documents are represented by Mdbc.Dictionary with underlying BsonDocument. See New-MdbcData for details. Use of its Lazy or Raw form may improve performance in some cases. In some scenarios other output types may be suitable like native .NET types (-As ([Type])) and PowerShell custom objects (-As PS). On choosing an output type keep in mind that Mdbc.Dictionary (BsonDocument) field names are case sensitive unlike object properties in PowerShell.</maml:para> </maml:description> </command:parameter> <command:parameter required="false" position="named" > <maml:name>FileFormat</maml:name> <maml:description> <maml:para>Specifies the data file format: Bson BSON format Json JSON format Auto (default) The format is defined by the file extension: ".json" is for JSON, other extensions are for BSON.

Save-MdbcFile is used in order to save data to the source file or another file. Such scenarios do not require MongoDB running or even installed. NORMAL AND SIMPLE DATA In the normal mode which is the default documents in a file must have unique _id's. If new documents have no _id's then they are generated on insertions. The simple mode is specified by the switch Simple. Presence and uniqueness of document _id's is not maintained. Operations like Add-MdbcData -Update are not supported. INVALID ELEMENT NAMES Document element names like *.* and $* are invalid in collections because query and update expressions use the dot notation for nested items and special names $* for operators. Nevertheless Open-MdbcFile does not perform name checks on reading assuming that the file was created and maintained only by cmdlets listed above and it contains valid names. Remember that files created in a different way, for example by Export-MdbcData, may contain problematic names for using them as collections with Open-MdbcFile.</maml:para> </maml:description> <command:syntax> <command:syntaxItem> <maml:name>Open-MdbcFile</maml:name> <command:parameter required="false" position="1" > <maml:name>Path</maml:name> <command:parameterValue required="true">String</command:parameterValue> </command:parameter> <command:parameter required="false" position="named" > <maml:name>CollectionVariable</maml:name> <command:parameterValue required="true">String</command:parameterValue> </command:parameter> <command:parameter required="false" position="named" > <maml:name>FileFormat</maml:name> <command:parameterValue required="true">FileFormat</command:parameterValue> </command:parameter> <command:parameter required="false" position="named" > <maml:name>NewCollection</maml:name> </command:parameter> <command:parameter required="false" position="named" > <maml:name>Simple</maml:name> </command:parameter> </command:syntaxItem> </command:syntax> <command:parameters> <command:parameter required="false" position="1" > <maml:name>Path</maml:name> <maml:description> <maml:para>Specifies the bson file path.
