How to start `powercfg.exe -energy` from a .NET app?

Question

When I

using (var process = new Process
{
    StartInfo = new ProcessStartInfo
    {
         FileName = "powercfg.exe",
         Arguments = "-energy",
         RedirectStandardOutput = true,
         UseShellExecute = false,
    }
})
{
    process.Start();
    process.WaitForExit();
}

It outputs:

A biblioteca de Diagnóstico de Eficiência de Consumo de Energia (energy.dll) não pôde ser carregada.

Translated to English:

The Energy Consumption Efficiency Diagnostic library (energy.dll) couldn't be loaded.

Even when running as admin.

Answer 1

Set the WorkingDirectory to the path energy.dll and powercfg.exe is located.

Answer 2

The error message seems to be generated by the program itself, a system generated message would look different. Is there any command line argument or other configuration for powercfg.exe where it will load it's dll's?

Or perhapse any hint in the manual of powercfg.exe where it will look for it's dll's .

I'm afraid I cannot duplicate your results; I get the results file as expected. But if it helps, perhaps my testing parameters will help you narrow down what may be the culprit in your environment:

• Running Visual Studio 2010 as Administrator
• Targeted .NET 4 Client Profile
• Compiled both x86 and Any CPU binaries
• Computer is running Windows 7 x64
