Solution 2

The method string.IndexOf() returns an integer. You should expand the expression to make it a boolean by comparing the result to zero.

okk.. Thanks for answer.. But i think the code is right plz check it

try {
string requestedDomain = HttpContext.Current.Request.Url.ToString().toLower();

if (Strings.InStr(requestedDomain, "http://yoursite.com")) {
requestedDomain = requestedDomain.Replace("http://yoursite.com", "http://www.yoursite.com");

Response.Clear();
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location", requestedDomain);
Response.End();

}

} catch (Exception ex) {
Response.Write("Error in Global.asax :" + ex.Message);
}

I think the error message is self explanatory. You are try to evaluate a int in a IF Block, and it should be a boolean.

Your code should look something like this:

C#

if ((requestedDomain.IndexOf("http://yoursite.com") + 1) > 1)
{
    // > 1 is just an example...
}

thx!

Solution 4

If() block is a conditional statement and it only checks whether the value in the braces is of type boolean or not.

Since the value in your if statement is of type int it should be equated to an another integer value

int age;
age=27;
like if(age==18)
{
//do something
}
else
{
// do some thing
}
