  The error message is telling you @imgeSrc is defined as a List<string>.  An index is required to get to the value.

  @imgeSrc[0]

  You might have to rethink the design if you are expecting a string.  Or maybe you need a loop?

  why not put value in ViewBag and access it. Well you can define a variable which can hold string and you can access it in Razor view, if you have List<string> then you  have to specify its index. like List<string> r= new List<string>(); r.Add("hello");

  In view : @r[0].ToString();

  Hi AltFire,

  AltFire

  how to get actual vlaue of the variable in razor syntax.

  Do you access a public variable in View page? You can try to pass your data using ViewModel or ViewBag ect.
