Hi, I am displaying message in c# like this

Response.Write( "<script>al ert( 'Sum is 50' )</script>");
it is working fine,but it is not working when we take variable in aleart like

int a=25;
int b=25;
int sum=a+b;

Response.Write( "<script>alert( sum)</script>");
this is not working.

Try

 Response.Write("<script>alert(''+sum)");

sum is a variable in your c# code, not your javascript, so you will need something like:

int a=25;
int b=25;
int sum=a+b;
 
Response.Write("<script>alert('"+sum.ToString()+"')</script>");
 

Note: that inside the alert() I have included the ' on either side of the contents and not just a "
(So it's a ' followed by a " then +sum.ToString() + then " then ' )

Wouldn't it be easier to just write it like:

Response.Write(string.Format("<script>alert('{0}')</script>", sum));

Maybe, but I never liked the string formater. Reminds me too much of printf().

Ah, everyone has their quirks. I particularly like it. No right or wrong, I just thought in that example it would be easier to show what you were getting at like that.
