Create a Simple Class and Call Its Method from a cshtml File without using App_Code

Question

I have seen this related question Creating and Simple Class and Calling a Method from a cshtml File. How can we do that without using the App_Code folder?

In my project's root, I have a Something.cs class:

public class Something 
{
    public static void DoIt()  
    { 

    }
}

In my project's root, I also have index.cshtml with the following code:

@Something.DoIt()

The name Something does not exist in the current context of index.cshtml.

Answer 1

Have you tried to refer the projects library within the cshtml File

@using ProjectName;

Or refer to the object like this @ProjectName.Something.DoIt()

Answer 2

If you are accessing it on top of .cshtml or inside any HTML string template like for loop then

@{
   MvcDemo.Something.DoIt();
}

Inside BeginForm or the other then

@using (Html.BeginForm())
{
 MvcDemo.Something.DoIt();
}

Please Note MvcDemo is the namespace and if you direclty write @MvcDemo.Something.DoIt() you may get error.

Here are the steps that I needed to take.

1. Create a file called SomeThing.cs.
2. Place said file anywhere in the csproj root directory.
3. Add said file to the .csproj (this is what I forgot to do).
4. Add class SomeThing with method DoIt() to said SomeThing.cs file.
5. Call its methods from SomeFile.cshtml file.

E.g. SomeFile.cshtml

@SomeThing.DoIt() // this assumes class SomeThing is NOT inside a namespace.

My problem was not adding SomeThing.cs to the .csproj.
