To check a string contains specific word(here its user).

Question

Hi,

I need to check a string contains a specific user. If user exist, need to enable button else disable it. I have used two strings. One hard coded and other taking the user name once a user logged in. And i need to check the user name in the list of hardcoded string.

here is what i have written. But its not correct.

Eg:

string username can take "xyzcom\\design.department" then the button should be shown.

string finUser = "xyzcom\\design.department,xyzcom\\basil.jad,xyzcom\\aloshi.alex, xyzcom\\michel felx,xyzcom\\karim.hal,xyzcom\\shah shaan ";
string username = Page.User.Identity.Name;  //"xyzcom\\design.department" eg
if (finUser.Any(username.Contains))
{
Button2.Visible = true;
}
else
{
Button2.Visible = false;
}
