‘HttpRequestMessage’ Does Not Contain A Definition For ‘GetQueryNameValuePairs’

In this azure tutorial, we will discuss how to fix the error, ‘HttpRequestMessage’ Does Not Contain A Definition For ‘GetQueryNameValuePairs’. This error I got after executing the Azure Function Code to interact with the Sharepoint From Azure Function using the Visual Studio 2019.

‘HttpRequestMessage’ Does Not Contain A Definition For ‘GetQueryNameValuePairs’

Recently, I was trying to write one Azure Function to connect to Share Point and to delete a SharePoint list. I came across with few lines of code that are not supported with the latest version of Azure Function.

• How To Create Azure Functions In Visual Studio

Below was my function code

using System;
using System.IO;
using System.Threading.Tasks;
//using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
//using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using System.Collections.Generic;
using Microsoft.SharePoint.Client;
using System.Net;
using System.Net.Http;
//using Microsoft.AspNetCore.Mvc.WebApiCompatShim;
using System.Linq;

namespace deletesplistvs
{
    public static class Function1
    {
        [FunctionName("NewFunction")]
        public static async Task<HttpResponseMessage> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequestMessage request,
            ILogger log)
        {

            string site = "https://tsinfo.sharepoint.com/sites/SPFx/";
            string userName = "bhawana@tsinfo.onmicrosoft.com";
            string password = "Bijay@12345";

            // parse query parameter  
            string listtitle = request.GetQueryNameValuePairs()
                .FirstOrDefault(q => string.Compare(q.Key, "title", true) == 0)
                .Value;


            System.Security.SecureString secureString = new System.Security.SecureString();
            foreach (char ch in password)
            {
                secureString.AppendChar(ch);
            }

When I started executing the code, I go the below error

‘HttpRequestMessage’ Does Not Contain A Definition For ‘GetQueryNameValuePairs’

Below is the Complete error message

Error CS1061 ‘HttpRequestMessage’ does not contain a definition for ‘GetQueryNameValuePairs’ and no accessible extension method ‘GetQueryNameValuePairs’ accepting a first argument of type ‘HttpRequestMessage’ could be found (are you missing a using directive or an assembly reference?) deletesplistvs C:\Users\Bijay\source\repos\deletesplistvs\deletesplistvs\Function1.cs 32

You can able to see the error as below

‘HttpRequestMessage’ Does Not Contain A Definition For ‘GetQueryNameValuePairs’ [Solved]

To fix the error ‘HttpRequestMessage’ Does Not Contain A Definition For ‘GetQueryNameValuePairs’, I am sorry to say that you have to downgrade the Azure Function version in your .csproj file.

Open your Azure Function project file i.e Projectname.csproj and do the below changes

<PropertyGroup>
    <TargetFramework>net461</TargetFramework>
    <AzureFunctionsVersion>v1</AzureFunctionsVersion>
  </PropertyGroup>

Below are the changes as highlighted

Now if you will run the Project you will not get the error

But, Personally I feel again going back to the older version of the Azure Function is not at all a good Idea and looks a bit uneasy You can try using the below way

You can use the HttpRequest req as the parameter and can use in the following way

string name = req.Query["name"];

public static class MyProductHTTPFunction
    {
        [FunctionName("MyProductHTTPFunction")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log, ExecutionContext context)
        {
            log.LogInformation("MyProductHTTPFunction function processed a request.");

            string name = req.Query["name"];

In this way you can fix the error ‘HttpRequestMessage’ Does Not Contain A Definition For ‘GetQueryNameValuePairs’.
