Question on MVC

Hi Experts,

We have MVC4 Application and am going through the code and found following statement in index.cshtml file to get login ID.

var loginID='@((User as Sample.Project.Principal.Administrator).Name);

Open in new window

1)can anyone briefly explain User as in  the above statement

2)How can I write above statement without using "User as "

Thanks in Advance

1) That line casts the User variable/property to a Sample.Project.Principal.Administrator object and then gets the value of its Name property.

2) That depends on the native type of User and if it natively supports a Name property.

To add to carl_tawn's #1, there is an (possibly valid) assumption here that User *is* or *descends from* the Sample.Project.Principal.Administrator class. If it does not, then the as operator will return null, and the access of the Name property will throw a NullReferenceException. The as operator will successfully cast if the type is compatible, or it will return null. Generally speaking, you should be checking for the null return when using as.
