    Using IUmbacorContextFactory in .cshtml file in App_Code

    Hi

    I am fairly new to low level coding with Umbraco.

    I have worked with Umbraco 7 and in App_Code created a cshtml file to provide some core shared functionality which I would then call from any templates/partial views.

    Eg I would like to have a function where I could pass a node id and return either a single property value or multiple.

    I achieved this in Umbraco 7 using

    public class myDoc {

        private IPublishedContent fetchDoc;
        private int _docID;
    
        public myDoc(int docID)
        {
            _docID = docID;
            fetchDoc = umbracoHelper.Content(docID);
        }
    
        public string docId(){
            return _docID.ToString();
        }
    
    
        public System.Web.HtmlString propertyValue(string strPropertyName)
        {
            var strValue = "";
            try{
                strValue = fetchDoc.GetPropertyValue(strPropertyName).ToString();   
            }
            catch(Exception ex){
                strValue = "Error - invalid document field name (" + strPropertyName + ")";
            }
    
            var nContent = new HtmlString(strValue);
    
            return nContent;
        }
    }
    

    And called this from a template

    However, this doesn't work in Umbraco 8 (at least not the way it did) and my reading says I should now use IUmbracoContextFactory

    However, I don't know how to instantiate this?

    My cshtml code is

    @using Umbraco
    @using Umbraco.Core.Services
    @using Umbraco.Web
    @using Umbraco.Core.Models.PublishedContent
    @using System.Web
    
    
    @functions{
    
    public static IPublishedContent test(IUmbracoContextFactory _umbracoContextFactory,int Id){
        var umbracoContextReference = _umbracoContextFactory.EnsureUmbracoContext();
        var content = umbracoContextReference.UmbracoContext.Content.GetById(Id);  
    
        return content;
    
    }
    

    and my template code is

        @inherits Umbraco.Web.Mvc.UmbracoViewPage<ContentModels.HomePage>
        @using ContentModels = Umbraco.Web.PublishedModels;
        @using owClasses;
        @{
            Layout = "standardContentMaster.cshtml";
        }
    
    
        @{
        var idHomePage = 1154;
        var tempvar_0 = @owRazorExtend.test(Umbraco,idHomePage);
        }
    
    @section Body
    {
    
    <h1>Test</h1>
    
      <h4>@tempvar_2</h4>
    }
    

    and I get error

    Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

    Compiler Error Message: CS1503: Argument 1: cannot convert from 'Umbraco.Web.UmbracoHelper' to 'Umbraco.Web.IUmbracoContextFactory'

    Source Error:

    Line 9: @{ Line 10: var idHomePage = 1154; Line 11: var tempvar_0 = @owRazorExtend.test(Umbraco,idHomePage); Line 12: } Line 13:

    so clearly I am passing the wrong reference to test.

    Can any one advise?

    Is there any documentation on this stuff eg the class, methods and properties in the various namespaces?

    Many thanks
