在@Html.Raw 中输出 Razor 代码

Question

I am trying to print a string in Razor using the following code:

@Html.Raw("Welcome @(ViewBag.Content.User.Name)!")

The output of this string is unfortunately: "Welcome @(ViewBag.Content.User.Name)!". But when I print it this way:

@Html.Raw("Welcome " + @(ViewBag.Content.User.Name) + "!")

The output of the string is: "Welcome Yanick!", just what I want but I don't want to print it this way. Is there a possibility to run the Razor code that is inside a string (see first example)? I tryed also Html.Encode() but this didn't work either...

You can use C# version 6.0 feature, called string interpolation.

In your case, it would be:

@Html.Raw($"Welcome {ViewBag.Content.User.Name}!")

If you're using C# version < 6.0, then string.Format is your choice:

@Html.Raw(string.Format("Welcome {0}!", ViewBag.Content.User.Name))
