I have some PowerShell code that is using a COM API. I am getting a Type Mismatch error when I pass in a byte array. Here is how I am creating the array, as well as some type information
PS C:\> $bytes = Get-Content $file -Encoding byte PS C:\> $bytes.GetType() IsPublic IsSerial Name BaseType -------- -------- ---- -------- True True Object[] System.Array PS C:\> $bytes[0].GetType() IsPublic IsSerial Name BaseType -------- -------- ---- -------- True True Byte System.ValueType Poking around with the API, I have found that it is looking for a Byte[] with a base type of System.Array.
PS C:\> $r.data.GetType() IsPublic IsSerial Name BaseType -------- -------- ---- -------- True True Byte[] System.Array PS C:\> $r.data[0].gettype() IsPublic IsSerial Name BaseType -------- -------- ---- -------- True True Byte System.ValueType What I am trying to do is convert $bytes into the same type as $r.data. For some reason, $bytes is getting created as an Object[]. How can I cast it to a Byte[]?

[IO. File]::WriteAllBytes() is the correct way of writing bytes to a file in PowerShell.
All variables in PowerShell are .NET objects, including 8-bit unsigned integer bytes. A byte object is an object of type System.Byte in the .NET class library, hence, it has properties and methods accessible to PowerShell (you can pipe them into get-member).
To create and initialize an array, assign multiple values to a variable. The values stored in the array are delimited with a comma and separated from the variable name by the assignment operator ( = ). The comma can also be used to initialize a single item array by placing the comma before the single item.
A byte array is simply an area of memory containing a group of contiguous (side by side) bytes, such that it makes sense to talk about them in order: the first byte, the second byte etc..
This answer is for the question with no context. I'm adding it because of search results.
