net 5 web api 部署到iis 不能使用process 调用 bat 、cmd 、powershell 取回结果么？

//执行获取结果    
var output1 = Cmd("powershell", "Get-Counter -Counter '\\Processor(_Total)\\% Processor Time' -MaxSamples 1");

public static string Cmd(string fileName, string args)
{
string output = string.Empty;
var info = new ProcessStartInfo();
info.FileName = fileName;
info.Arguments = args;
info.RedirectStandardOutput = true;
using (var process = Process.Start(info))
{
process.WaitForExit();
output = process.StandardOutput.ReadToEnd();
}
return output;
}
