Razor expression
A Razor expression is an inline construct that evaluates an embedded C# expression and inserts its result into generated output.
Pro ASP.NET Core 7, Tenth Edition
A Razor expression is an embedded expression in a Razor view that Razor evaluates to produce content in the generated response.
- How it is used
- Inserts evaluated C# values into HTML responses generated by Razor views and Razor Pages.
- How deep it goes
- Works through property access, method calls, arithmetic boundaries, and attributes, then identifies generated C# calls without tracing compilation in detail.
- Examples
- Uses a product table, currency formatting, contrasting tax calculations, a rendered data-id attribute, and page-model property access.
- What you can do after
- Build it from scratch in a .cshtml view to insert model values and avoid mistaking arithmetic for literal content.

ASP.NET Core in Action, 3e
A Razor expression is an inline Razor construct that evaluates a C# expression and writes its result to the generated HTML output.
- How it is used
- Renders C# values from Razor Pages models or ViewData directly into dynamic HTML.
- How deep it goes
- Defines @, @(), and @@ syntax, contrasts expressions with @{} code blocks, and extends into loops and conditionals.
- Examples
- Uses copyright text, arithmetic output, and a to-do list rendered conditionally from model data.
- What you can do after
- Apply it via Razor syntax to render model values and generate data-dependent HTML without manually building response strings.
