The name 'Request' does not exist in the current context

We have in our old Umbraco (v8) a 'GetSocialMeta' partial. Obviously it won't work in our new Umbraco (v10) projects.

This is the code:

@inherits Umbraco.Web.Mvc.UmbracoViewPage
@{
    string title = String.Empty;
    string hyperlink = String.Format("https://{0}{1}", Request.Url.Host, Request.Url.AbsolutePath);
    string ogImageUrl = String.Empty;
    string twitterName = String.Empty;
    string canonicalURL = String.Empty;
    string omschrijving = String.Empty;
    string twitterTitle = String.Empty;
}
@if (Model.HasValue("canonicalURL")){
    canonicalURL = Model.Value<string>("canonicalURL");
}
else{
    canonicalURL = @hyperlink;
}
@if (Model.HasValue("browserTitle")){
    title = Model.Value<string>("browserTitle");
}else if (Model.HasValue("paginaTitel")){
    title = Model.Value<string>("paginaTitel");
}else{
    title = Model.Name;
}
@if (Model.Value<string>("twitterNaam", fallback: Fallback.ToAncestors) != String.Empty){
    twitterName = Model.Value<string>("twitterNaam", fallback: Fallback.ToAncestors);
}
@if (Model.Value<IPublishedContent>("ogImage", fallback: Fallback.ToAncestors) != null){
    IPublishedContent ogImage = Model.Value<IPublishedContent>("ogImage", fallback: Fallback.ToAncestors);
    ogImageUrl = String.Format("http://{0}{1}", Request.Url.Host, ogImage.Url);
}else{
    ogImageUrl = String.Format("http://{0}/images/logo-fb.png", Request.Url.Host);
}
@if (Model.HasValue("twitterTitel")){
    twitterTitle = Model.Value<string>("twitterTitel");
}else{
    twitterTitle = title; 
}
@if (Model.HasValue("omschrijving")){
    omschrijving = Model.Value<string>("twitterOmschrijving");
}else{
    omschrijving = Model.Value<string>("metaDescription");
}
@{ 
    <meta property="og:title" content="@title" />
    <meta property="og:type" content="website" />
    <meta property="og:url" content="@hyperlink" />
    <meta property="og:image" content="@ogImageUrl" />
    <meta property="og:description" content="@omschrijving" />
    <meta name="twitter:site" content="@twitterName" />
    <meta name="twitter:creator" content="@twitterName" />
    <meta name="twitter:card" content="summary_large_image" />
    <meta name="twitter:title" content="@twitterTitle" />
    <meta name="twitter:description" content="@omschrijving">
    <meta name="twitter:image" content="@ogImageUrl" />
    <link rel="canonical" href="@canonicalURL">
}

These are the errors we get: An error occurred during the compilation of a resource required to process this request. Please review the following specific error details and modify your source code appropriately.

The name 'Request' does not exist in the current context
+
    string hyperlink = String.Format("https://{0}{1}", Request.Url.Host, Request.Url.AbsolutePath);
The name 'Request' does not exist in the current context

    ogImageUrl = String.Format("http://{0}{1}", Request.Url.Host, ogImage.Url);
The name 'Request' does not exist in the current context

    ogImageUrl = String.Format("http://{0}/images/logo-fb.png", Request.Url.Host);

Is there a way to fix this or a better way to set it up?

just noticed
```
@inherits Umbraco.Web.Mvc.UmbracoViewPage
```
That is not correct for Umbraco 9, IIRC it should be
```
Umbraco.Cms.Web.Common.Views.UmbracoViewPage
```

Probably because i'm a pretty noob in back-end coding. I've no idea how to get this work in our code (above)

I'm not sure either as it just works for me. I just did a quick test and created a partialView as below
```
@inherits UmbracoViewPage
@{

    string hyperlink = String.Format("https://{0}{1}", Context.Request.Host, Context.Request.Path);

}
```
I then included it in my main page @await Html.PartialAsync("Layout/_TestPartial") and it works with no errors

This works indeed. But how do i get it to work for:
```
ogImageUrl = String.Format("http://{0}{1}", Request.Url.Host, ogImage.Url);
```
&
```
ogImageUrl = String.Format("http://{0}/images/logo-fb.png", Request.Url.Host);
```
Because if i adjust it the same way it still won't work

I was too quick with my reply (deleted) Just replace them gives me other errors

Argument 1: cannot convert from 'string' to 'System.IFormatProvider?'
+
    ogImageUrl = String.Format("http://{0}{1}", Context.Request.Host, ogImage.Url);
Argument 2: cannot convert from 'Microsoft.AspNetCore.Http.HostString' to 'string'
+
    ogImageUrl = String.Format("http://{0}{1}", Context.Request.Host, ogImage.Url);
Argument 3: cannot convert from 'method group' to 'object?'
+
    ogImageUrl = String.Format("http://{0}{1}", Context.Request.Host, ogImage.Url);

I think it may need to be ogImage.Url() not ogImage.Url

Ah f*ck, that's it. I still have to get used to that extra () compared to Umbraco 8.

Thanks for your help and above all patience.
