Hi,

I need to convert this VB code to C#, can anybody help?

I have tried this, but it does not compile.

PSObject powershellresult = new System.Collections.ObjectModel.Collection<PSObject>;

or PSObject powershellresult = new System.Collections.ObjectModel.Collection<PSObject>();

any idea?

Hi Peter

First, you should reference the “Microsoft.PowerShell.5.ReferenceAssemblies”.

https://www.nuget.org/packages/Microsoft.PowerShell.5.ReferenceAssemblies/

And the reason why the compilation fails is inconsistent type.

From your description, I think you want to define “powershellresult” as a collection type, so you can change it like below:

System.Collections.ObjectModel.Collection<PSObject> powershellresult = new System.Collections.ObjectModel.Collection<PSObject>();

Or you can simply use `var` to ask the compiler to infer the type:

var  powershellresult = new System.Collections.ObjectModel.Collection<PSObject>();

PSObject powershellresult = new System.Collections.ObjectModel.Collection<PSObject>;

PSObject is not a collection and is most likely just a single object. So you cannot cast a collection of PSobject(s) to be a PSObject, becuase PSObject is not a collection.

System.Collections.ObjectModel.Collection<PSObject> powershellresult = new System.Collections.ObjectModel.Collection<PSObject>;

the above may work

OR

var powershellresult = new System.Collections.ObjectModel.Collection<PSObject>; // strong types the object.
