Something like this

var somepath = Path.GetTempPath(); // tempFolder if you want it
var fileName = Path.Combine(somepath,$"{Guid.NewGuid()}.dat");

// Do something with your file name

Add pepper and salt to taste

Additional resources

Path.Combine Method

Combines strings into a path.

Guid.NewGuid Method

Initializes a new instance of the Guid structure.

Example

public static void Main()
{
    Guid g;
    // Create and display the value of two GUIDs.
    g = Guid.NewGuid();
    Console.WriteLine(g);
    Console.WriteLine(Guid.NewGuid());
}

Output

the Guid type has a Guid.NewGuid() method that generates a 'random' guid.

also check out this post that discusses pros and cons of newing up a guid type v using the built in newguid().
