Ошибка cs1061 в visual studio

I am new to .NET visual studio, building windows Form Application.

I had the following error described below, when trying to build a solution. I am not sure if it has to do with something related to the file ‘SuperAdventure.SuperAdventure’ or a control that was not specified.

‘SuperAdventure.SuperAdventure’ does not contain a definition for ‘label5_Click‘ and no extension method ‘label5_Click’ accepting a first argument of type ‘SuperAdventure.SuperAdventure’ could be found (are you missing a using directive or an assembly reference?)

This is the error code with the error showing a red squiggly/line under the code in the marked line.

// lblExperience
// 
this.lblExperience.AutoSize = true;
this.lblExperience.Location = new System.Drawing.Point(110, 73);
this.lblExperience.Name = "lblExperience";
this.lblExperience.Size = new System.Drawing.Size(35, 13);
this.lblExperience.TabIndex = 6;
this.lblExperience.Text = "label7";
this.lblExperience.Click += new System.EventHandler(this.label5_Click); // <-- squiggly line here

and on the output it gives this:

1. 1>—— Build started: Project: Engine, Configuration: Release Any
   CPU ——

2. 1> Engine -> C:UsersAdminDocumentsVisual Studio
   2013ProjectsSuperAdventureEnginebinReleaseEngine.dll

Please let me know if I need to provided any more information.

I’m having a bit of a pain here and I just can’t figure out what’s wrong.

I have an ASP.net project which I deployed on a server. At first everything seemed allright, no Errors whatsoever. However, as a last adition I wanted to add a search function to a fairly large list so I added the following syntax to my mark-up:

<td>
    Search Server:
    <asp:TextBox ID="txtSearch" runat="server" />
    <asp:Button ID="btnLookup" runat="server" OnClick="btnLookup_Clicked" Text="Search" />
    <asp:Label ID="lblFeedback" runat="server" />
</td>

and the following in code behind:

protected void btnLookup_Clicked(object sender, EventArgs e)
{
    lblFeedback.Text = "";
    Session["IsSearch"] = true;
    LoadServerList();
}

When I run this locally it works just fine as I expect.
HOWEVER!

When I copy these files to the server I get a compilation error:

Compiler Error Message: CS1061: ‘ ASP.ntservice_ reports_ reports_ serverlist_ manage_ aspx ‘ does not contain a definition for ‘btnLookup_ Clicked’ and no extension method ‘btnLookup_ Clicked’ accepting a first argument of type ‘ASP.ntservice_ reports_ reports_ serverlist_ manage_ aspx’ could be found (are you missing a using directive or an assembly reference?)

it says there is nothing that handles my Clicked event although it does work when I run it through Visual studio.

any ideas?

EDIT:
What I tried myself is

• renaming button
• deleting and readding the button
• add through designer
• renaming click event
• removing the event from markup allows normal execution … :/

In this azure tutorial, we will discuss how to fix the error, CS1061 C# ‘HttpRequest’ does not contain a definition for ‘Content’ and no accessible extension method ‘Content’ accepting a first argument of type ‘HttpRequest’ could be found which comes while trying to create an Azure Function using Visual Studio 2019.

Recently, I was developing an Azure Function using Visual Studio 2019 and while executing the function i got the error CS1061 C# ‘HttpRequest’ does not contain a definition for ‘Content’ and no accessible extension method ‘Content’ accepting a first argument of type ‘HttpRequest’ could be found.

I was trying to execute the below C# function as part of Azure Function creation functionality.

 public static class Function1
    {
        [FunctionName("Function1")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log, [Queue("EmpInfo", Connection = "AzureWebJobsStorage")] IAsyncCollector<UserDetails> outputQueue)
        {
            
            string jsoncnt = await req.Content.ReadAsStringAsync();
            var myDetails = JsonConvert.DeserializeObject<UserDetails>(jsoncnt);
            log.LogInformation($"Appreciation {myDetails.UserId} received from {myDetails.UserEmail} for the emp id {myDetails.UserId}");
            await outputQueue.AddAsync(myDetails);


            log.LogInformation("C# HTTP trigger function processed a request.");

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

            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
            name = name ?? data?.name;

            return name != null
                ? (ActionResult)new OkObjectResult($"Hello, {name}")
                : new BadRequestObjectResult("Please pass a name on the query string or in the request body");
        }
    }

I got the error on the below line

string jsoncnt = await req.Content.ReadAsStringAsync();

The exact error message was CS1061 C# ‘HttpRequest’ does not contain a definition for ‘Content’ and no accessible extension method ‘Content’ accepting a first argument of type ‘HttpRequest’ could be found (are you missing a using directive or an assembly reference?)

You can see as below

CS1061 C# ‘HttpRequest’ does not contain a definition for ‘Content’ and no accessible extension method ‘Content’ accepting a first argument of type ‘HttpRequest’ could be found [Solved]

Now to fix this error you need to follow the below steps.

Right click on the Project and click on the Manage NuGet Packages.

You can search for Microsoft.AspNet.WebApi.Client and then click on the install button to install it.

Or you can open the Nuget manager console and execute the below command to install Microsoft.AspNet.WebApi.Client.

Install-Package Microsoft.AspNet.WebApi.Client

Alternatively, you need to add reference the System.Net.Http.Formatting.dll to your project.

You need to right click on your project —> Add —> Reference

Now Browse or search for the below dll and then click on the Ok button to add the dll reference to your project

If you will implement the above process then it will fix this error.

Conclusion

Well, in this article, we discussed how to fix the error CS1061 C# ‘HttpRequest’ does not contain a definition for ‘Content’ and no accessible extension method ‘Content’ accepting a first argument of type ‘HttpRequest’ could be found, httpcontext does not contain a definition for current, which I got while creating an Azure Function using the Visual Studio 2019. Hope it will fix your issue !!!
