Below is the code:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using System.Management.Automation;

using System.Management.Automation.Runspaces;

using System.Collections.ObjectModel;

using Microsoft.PowerShell.Commands;

using Newtonsoft.Json;

namespace powershelltest

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void textBox1_TextChanged(object sender, EventArgs e)

{

}

private string RunScript (string Script)

{

Runspace runspace = RunspaceFactory.CreateRunspace();

runspace.Open();

Pipeline pipeline = runspace.CreatePipeline();

//pipeline.Invoke("Set-ExecutionPolicy Unrestricted");

pipeline.Commands.AddScript(Script);

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

Collection results = pipeline.Invoke();

runspace.Close();

StringBuilder stringBuilder = new StringBuilder();

foreach (PSObject pSObject in results)

stringBuilder.AppendLine(pSObject.ToString());

return stringBuilder.ToString();

}

private void button1_Click(object sender, EventArgs e)

{

textBox2.Clear();

textBox2.Text = RunScript(textBox1.Text);

}

“Create an Azure Key Vault and Secret”. one for the ID and second for the PASSWORD

private static async Task<string> GetAccessToken(string tenantId, string clientId, string clientKey)
{
    WriteLine("Begin GetAccessToken");
    string authContextURL = "https://login.windows.net/" + tenantId;
    var authenticationContext = new AuthenticationContext(authContextURL);
    var credential = new ClientCredential(clientId, clientKey);
    var result = await authenticationContext
        .AcquireTokenAsync("https://management.azure.com/", credential);
    if (result == null)
    {
        throw new InvalidOperationException("Failed to obtain the JWT token");
    }
    string token = result.AccessToken;
    return token;
}

You need to include the “Microsoft.IdentityModel.Clients.ActiveDirectory” package into the project. It is installable via NuGet…love that NuGet stuff BTW. This method receives the tenant id which I mentioned earlier, I.e. the Azure Active Directory directory id, the application id and the password key of the service principle. The method returns the token. Then you can run the REST API, which I did like this.

private static async Task<string> RestartWebApp(string token)
{
    WriteLine("Begin RestartWebApp");
    string URL = "https://management.azure.com/subscriptions/{subscriptionId}" + 
                 "/resourceGroups/{RGName}/providers/Microsoft.Web/sites/" + 
                 "{siteName}/restart?softRestart=false&synchronous=false?" +
                 "api-version=2016-08-01";
    httpClient.DefaultRequestHeaders.Remove("Authorization");
    httpClient.DefaultRequestHeaders.Add("Authorization", "Bearer " + token);
    HttpResponseMessage response = await httpClient.PostAsync(URL, null);
    return response.StatusCode.ToString();
}

please refer this blog "https://blogs.msdn.microsoft.com/benjaminperkins/2018/09/27/how-to-securely-connect-to-azure-from-c-and-run-rest-apis/" in more detail.i hope that can help you.
