Concatenating strings in Razor

How would I join two strings in Razor syntax?

If I had: @Model.address and @Model.city and I wanted the out put to be address city what would I do? Is it as simple as doing @Model.address + " " + @Model.city?

Use the parentesis syntax of Razor:

@(Model.address + " " + Model.city)

or

@(String.Format("{0} {1}", Model.address, Model.city))

Update: With C# 6 you can also use the $-Notation (officially interpolated strings):

@($"{Model.address} {Model.city}")

String.Format also works in Razor:

String.Format("{0} - {1}", Model.address, Model.city)

You can give like this....

<a href="@(IsProduction.IsProductionUrl)Index/LogOut">
