Question

i would like to refactor this code. Maybe if possible by using a switch? Or is it the same in terms of performance?

string rawUrl = context.Request.RawUrl ?? string.Empty;

if (rawUrl.Contains("mypage.aspx"))
{
}

if (rawUrl.Contains("mypage2.aspx"))
{
}

etc..

Switch Cases must be a constant value. You’re best bet there is to use if/else like so:

string rawUrl = context.Request.RawUrl ?? string.Empty;

if (rawUrl.Contains("mypage.aspx"))
{
    //code
}
else if (rawUrl.Contains("mypage2.aspx"))
{
    //more code
}

If you’re concerned about performance (which is good!) then the else is the way to go. While not using an else will have the same functionality, by adding the else, you’re telling the code to not process any of the other if conditions. So 10 if statements will result in 10 if conditions being processed not matter what, while 10 if/else statements might result in 10, or it might only result in 1.

EDIT:

Thought about this some, and I noticed you were using the context object. If you really wanted a switch statement, you can do the following:

string page = context.Request.Url.Segments.Last();

switch(page)
{
    case "mypage.aspx":
        //code
        break;
    case "mypage2.aspx":
        //more code
        break;
}
