In C# a RemoveAllFilesByExtenstion subroutine could be, for example, decleard like this:
void RemoveAllFilesByExtenstion(string targetFolderPath, string ext)
{
...
}
and used like:
RemoveAllFilesByExtenstion("C:\Logs\", ".log");
How can I defne and call a subroutine with the same signature from a PowerShell script file (ps1)?

PowerShell uses the parameter value order to associate each parameter value with a parameter in the function. When you use positional parameters, type one or more values after the function name. Positional parameter values are assigned to the $args array variable.
Pretty simple to convert this to PowerShell:
function RemoveAllFilesByExtenstion([string]$targetFolderPath, [string]$ext)
{
...
}
But the invocation has to use space separated args but doesn't require quotes unless there's a PowerShell special character in the string:
RemoveAllFilesByExtenstion C:\Logs\ .log
OTOH, if the function is indicative of what you want to do, this can be done in PowerShell easily:
Get-ChildItem $targetFolderPath -r -filter $ext | Remove-Item
