  It should not give.

  But still if this is the case then you can write 

  var st2 = st1[0].ToString()+st1[1].ToString();

  Thanks & Regards

  The correct syntax is

  @{
  var st1 ="asd";
  var st2 = st1.Substring(0,2);
  }
  <h1>@st2</h1>

  Dear uahmed..

  This is because of the + operator.. 

  var st2 = st1[0]+st1[1];

  because if you use + then C# will assume both the operands as Integer and take the ascii value of the alphabets

  st2 = 97 + 115;

  97 is ascii of a

  and 115 is for s
