Question

I have no experience on creating Power Shell scripts and I’m trying to instantiating System.IO.StreamWriter class providing a specific text encoding. I’m trying to do this:

$file = New-Object System.IO.StreamWriter("sample.txt", [System.Text.Encoding]::Default, 4096)

And I’m getting the following error message:

New-Object : Cannot find an overload for "StreamWriter" and the argument count: "3". 
At line:1 char:18 
    + $out = New-Object <<<<  System.IO.StreamWriter("sample.txt", [System.Text.Encoding]::Default, 4096)
    + CategoryInfo          : InvalidOperation: (:) [New-Object], MethodException
    + FullyQualifiedErrorId : ConstructorInvokedThrowException,Microsoft.PowerShell.Commands.NewObjectCommand

I looked at MSDN documentation StreamWriter Constructor (Stream, Encoding, Int32) and it has an overload with three parameters.

Does anyone know how to instantiate a System.IO.StreamWriter specifiying an encoding?

Thanks,

You’re trying to call StreamWriter(String, Encoding, Int32) – and that signature doesn’t exist. Admittedly the error message leaves a little to be desired… but basically you’ll either need to create the stream yourself, or using StreamWriter(String, Boolean, Encoding).
