将PS脚本的输出存储在C＃变量中

Question

我是C＃和PowerShell的新手。

我正在使用Azure Powershell。我已经尝试了很多方法来提取指标，但遗憾的是没有一种方法可以解决。我想在文本框或消息框中显示通过Get - AzureRMMetricDefinition获得的指标（稍后会对其进行过滤）。

代码已附加，除了Microsoft的登录页面外，它不会提供任何输出。

Answer 1

I do a test with the following code to run Get-AzureRmMetricDefinition, which works fine on my side, I can get account info and metric definitions after the code is executed.

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Management.Automation;
using System.Management.Automation.Runspaces;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            //run Login-AzureRmAccount
            Runspace runspace = RunspaceFactory.CreateRunspace();

            runspace.Open();

            Pipeline pipeline = runspace.CreatePipeline();

            var scriptText = "Login-AzureRmAccount";
            pipeline.Commands.AddScript(scriptText);

            pipeline.Commands.Add("Out-String");

            Collection<PSObject> results = pipeline.Invoke();


            runspace.Close();

            StringBuilder stringBuilder = new StringBuilder();
            foreach (PSObject obj in results)
            {
                stringBuilder.AppendLine(obj.ToString());
            }

            var accountinfo = stringBuilder.ToString();

            Console.WriteLine(accountinfo);


            //run Get-AzureRmMetricDefinition

            Runspace runspace1 = RunspaceFactory.CreateRunspace();

            runspace1.Open();

            Pipeline pipeline1 = runspace1.CreatePipeline();

            var subscription = "xxxxxxxxxxxx";
            var resourcegroup = "xxxxx";
            var appname = "xxxxx";

            //Get metric definitions with detailed output
            var MetricDefscriptText = $"Get-AzureRmMetricDefinition -ResourceId '/subscriptions/{subscription}/resourceGroups/{resourcegroup}/providers/microsoft.web/sites/{appname}' -DetailedOutput";
            pipeline1.Commands.AddScript(MetricDefscriptText);


            pipeline1.Commands.Add("Out-String");

            Collection<PSObject> Metrics = pipeline1.Invoke();


            runspace1.Close();

            StringBuilder stringBuilder1 = new StringBuilder();
            foreach (PSObject obj in Metrics)
            {
                stringBuilder1.AppendLine(obj.ToString());
            }

            var metricdefinitions = stringBuilder1.ToString();
            Console.WriteLine(metricdefinitions);
        }
    }
}

Output:

Same output if run it in Powershell:

If possible, you can create a console application and do a test with the code that I shared, and check whether it works on your side.
