How to implement Google Place API in C#.Net

I am developing a EPOS System in C#.NET. In My Project, i have to implement a scenario:
User will enter Zip Code/ Postal Code in a Text box.
Application using google places API will return City, Street and Town separately in 3 Tex box respectively.
Please any one help me how to implement this scenario in C#.net.
i already created Google Project on https://console.cloud.google.com/apis/credentials/key and generate Google Place API Key for my project.
I Have searched a lot on google but all example are implemented in asp.net, but i need in C# Net.
Anyone Help me.
Thanks in Advance.
I have implemented Some how but i don't know how to read it
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Web.Script.Serialization;
using Newtonsoft.Json;
namespace apidemo
{
class Program
{
String response, result;
const String apiKey= "My APi kEy";
static void Main(string[] args)
{
getdata("B11 4RA");
Console.ReadLine();
}
static async public void getdata(String code)
{
try
{
using (var client = new HttpClient())
{
var response = await client.GetStringAsync(String.Format("https://maps.googleapis.com/maps/api/place/autocomplete/json?key="+ apiKey + "&input=" +code));
Console.WriteLine(response);
}
}
catch (Exception ex) {
Console.Write(ex.ToString());
}
}
}
}
Output is this

If we look at the documentation for the Google Places API, we can see the format of the JSON that a request to the API returns. You can traverse the json object and get your required values as in below snippet.
JObject objectContainer = response.Value<JObject>("candidates");
foreach (KeyValuePair<string, JToken> tag in objectContainer)
{
if(tag.key=="formatted_address")
var address = tag.value;
if(tag.key=="name")
var name = tag.value;
}
With a simple HTTP request to the Google Places API, we can then use above code to get required fields.
using (var client = new HttpClient())
{
var response = await client.GetStringAsync("https://maps.googleapis.com/maps/api/place/findplacefromtext/json?input=YOUR_POSTCODE&inputtype=textquery&&fields=photos,formatted_address,name,opening_hours,rating&key=YOUR_API_KEY");
var result = JsonConvert.DeserializeObject<PlacesApiQueryResponse>(response);
}

Read image from private GitHub repository programmatically using C#

Need to store the image from a private git repository to a blob using C#. Tried with below code but getting 404 errors.
I am using the below code from
C# example of downloading GitHub private repo programmatically
var githubToken = "[token]";
var url =
"https://github.com/[username]/[repository]/archive/[sha1|tag].zip";
var path = #"[local path]";
using (var client = new System.Net.Http.HttpClient())
{
var credentials = string.Format(System.Globalization.CultureInfo.InvariantCulture, "{0}:", githubToken);
credentials = Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes(credentials));
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", credentials);
var contents = client.GetByteArrayAsync(url).Result;
System.IO.File.WriteAllBytes(path, contents);
}
Note: Able to fetch from the public repository

How to fix :
The URL is changed to GET /repos/:owner/:repo/:archive_format/:ref. See https://developer.github.com/v3/repos/contents/#get-archive-link
For private repositories, these links are temporary and expire after five minutes.
GET /repos/:owner/:repo/:archive_format/:ref
You should not pass the credentials using basic authentication. Instead, you should create a token by following the official docs. see https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line
Finally, you need pass an extra User-Agent header. It is required by GitHub API. See https://developer.github.com/v3/#user-agent-required :
All API requests MUST include a valid User-Agent header.
Demo
public class GitHubRepoApi{
public string EndPoint {get;} = "https://api.github.com/repos";
public async Task DownloadArchieveAsync(string saveAs, string owner, string token, string repo,string #ref="master",string format="zipball")
{
var url = this.GetArchieveUrl(owner, repo, #ref, format);
var req = this.BuildRequestMessage(url,token);
using( var httpClient = new HttpClient()){
var resp = await httpClient.SendAsync(req);
if(resp.StatusCode != System.Net.HttpStatusCode.OK){
throw new Exception($"error happens when downloading the {req.RequestUri}, statusCode={resp.StatusCode}");
}
using(var fs = File.OpenWrite(saveAs) ){
await resp.Content.CopyToAsync(fs);
}
}
}
private string GetArchieveUrl(string owner, string repo, string #ref = "master", string format="zipball")
{
return $"{this.EndPoint}/{owner}/{repo}/{format}/{#ref}"; // See https://developer.github.com/v3/repos/contents/#get-archive-link
}
private HttpRequestMessage BuildRequestMessage(string url, string token)
{
var uriBuilder = new UriBuilder(url);
uriBuilder.Query = $"access_token={token}"; // See https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line
var req = new HttpRequestMessage();
req.RequestUri = uriBuilder.Uri;
req.Headers.Add("User-Agent","My C# Client"); // required, See https://developer.github.com/v3/#user-agent-required
return req;
}
}
Test :
var api = new GitHubRepoApi();
var saveAs= Path.Combine(Directory.GetCurrentDirectory(),"abc.zip");
var owner = "newbienewbie";
var token = "------your-----token--------";
var repo = "your-repo";
var #ref = "6883a92222759d574a724b5b8952bc475f580fe0"; // will be "master" by default
api.DownloadArchieveAsync(saveAs, owner,token,repo,#ref).Wait();

According to the message you provide, you use the wrong url to download. Regarding how to get the download url, please refer to the following steps:
Use the following url to get the download url
Method: GET
URL: https://api.github.com/repos/:owner/:repo/contents/:path?ref:<The name of the commit/branch/tag>
Header:
Authorization: token <personal access token>
The repose body will tell you the download url
For example :
Download file

C# How can I call an http post method and get back the results

I have a method that is a http Post I call that method and pass along 2 parameter then it returns 2 parameters back . I have it working the traditional way but now I would like to get it working using RestSharp .I would like to call that method now using RestSharp but I am having no luck . This below works
public static void Main() {
var getController = new AccessController();
var merchSales = getController.Merchandise("Bags",5);
var status = merchSales.Status;
var items = merchSales.ItemsCount;
if (status.sold == status)
{
console("It's Sold");
}
else if (status.available == status)
{
console("It's Available");
}
}
I am now trying to do that using RestSharp http://restsharp.org/ . However How can I get back the return value of the Enum to do an If statement check like I did above ? For instance in the code above the merchSales.Status is an enum that will return either Available or Sold . This is my code below it's meant to be a HTTP call
public static void Main() {
var client = new RestClient ("http://localhost:1275/api/");
var request = new RestRequest("Resource/{id}", Method.POST);
request.AddParameter("Item", "Bags");
request.AddParameter("Count", 5);
RestResponse response = client.Execute(request);
client.ExecuteAsync(request, data => {
Console.WriteLine(data.Content);
});
}

What is the ASP.NET Core MVC equivalent to Request.RequestURI?

I found a blog post that shows how to "shim" familiar things like HttpResponseMessage back into ASP.NET Core MVC, but I want to know what's the new native way to do the same thing as the following code in a REST Post method in a Controller:
// POST audit/values
[HttpPost]
public System.Net.Http.HttpResponseMessage Post([FromBody]string value)
{
var NewEntity = _repository.InsertFromString(value);
var msg = new System.Net.Http.HttpResponseMessage(System.Net.HttpStatusCode.Created);
msg.Headers.Location = new Uri(Request.RequestUri + NewEntity.ID.ToString());
return msg;
}
In an ASP.NET Core MVC project, I can't seem to get Request.RequestUri.
I tried inspecting Request, and I was able to make a function like this:
private string UriStr(HttpRequest Request)
{
return Request.Scheme + "://" + Request.Host + Request.Path; // Request.Path has leading /
}
So I could write UriStr(Request) instead. But I'm not sure that's right. I feel like I'm hacking my way around, and not using this correctly.
A related question for earlier non-Core ASP.NET MVC versions asks how to get the base url of the site.

Personally, I use :
new Uri(request.GetDisplayUrl())
GetDisplayUrl fully un-escaped form (except for the QueryString)
GetEncodedUrl - fully escaped form suitable for use in HTTP headers
These are extension method from the following namespace : Microsoft.AspNetCore.Http.Extensions

A cleaner way would be to use a UriBuilder:
private static Uri GetUri(HttpRequest request)
{
var builder = new UriBuilder();
builder.Scheme = request.Scheme;
builder.Host = request.Host.Value;
builder.Path = request.Path;
builder.Query = request.QueryString.ToUriComponent();
return builder.Uri;
}
(not tested, the code might require a few adjustments)

Here's a working code. This is based off #Thomas Levesque answer which didn't work well when the request is from a custom port.
public static class HttpRequestExtensions
{
public static Uri ToUri(this HttpRequest request)
{
var hostComponents = request.Host.ToUriComponent().Split(':');
var builder = new UriBuilder
{
Scheme = request.Scheme,
Host = hostComponents[0],
Path = request.Path,
Query = request.QueryString.ToUriComponent()
};
if (hostComponents.Length == 2)
{
builder.Port = Convert.ToInt32(hostComponents[1]);
}
return builder.Uri;
}
}

Using twilio c# client to pass twilio response back

I am using the twilio c# wrapper and am able to receive communication from twilio. I am having trouble responding back to twilio with a response and having twilio recognize it. Currently I am trying to respond with a TwilioResponse. Anyone have a good example? This is a WebApi self hosted windows service.
ex. TwilioResponse().Message("ok");

I have used Same web API you can use the below menioned code but First you have to configure your APP in Twilio UserAccount.
public class WelcomeController : ApiController
{
public HttpResponseMessage Post(VoiceRequest request)
{
var response = new TwilioResponse();
response.Say("Welcome to Dhaval demo app. Please enter your 5 digit ID.");
response.Gather(new { numDigits = 5, action = string.Format("/api/Authenticate") });
return this.Request.CreateResponse(HttpStatusCode.OK, response.Element, new XmlMediaTypeFormatter());
}
}
When I press the 5 digit no then it will lend to Authetication Controller it' look like
public HttpResponseMessage Post(VoiceRequest request)
{
var response = new TwilioResponse();
var validIds = new List<string> { "12345", "23456", "34567" };
var userId = request.Digits;
var authenticated = validIds.Contains(userId);
if (!authenticated)
{
response.Say("You entered an invalid ID.");
response.Hangup();
}
else
{
response.Say("ID is valid.");
response.Redirect(string.Format("/api/Name?userId={0}", userId));
}
return this.Request.CreateResponse(HttpStatusCode.OK, response.Element, new XmlMediaTypeFormatter());
}
and it's work fine in my side, once again check it properly you have given the correct AuthToken
Cheers

After tinkering for a while, this seems to do the trick.
var twiml = new TwilioResponse().Message("test");
return TwilioResponse(twiml);
private HttpResponseMessage TwilioResponse(TwilioResponse twilioResponse)
{
return new HttpResponseMessage()
{
Content = new StringContent(twilioResponse.ToString(), Encoding.UTF8, "text/xml"),
StatusCode = System.Net.HttpStatusCode.OK
};
}
