hi you can pass the parameter username and password in databse and write query like if exists(select * from adminuser where username=@username and Password=@Password) , here @username and @password are your passing parameter value. If this value exist then return 1 for True and not exist then return 0 for False. Don't forget to Mark Do you like this Answer that solved your problem!
