How to declare a local variable in Razor

Question

I am developing a web application in asp net mvc 3  I am very new to it  In a view using razor  I d like to declare some local variables and use it across the entire page  How can this be done   It seems rather trivial to be able to do the following action    bool isUserConnected   string IsNullOrEmpty Model CreatorFullName    if  isUserConnected       meaning that the viewing user has not been saved      lt div gt           lt div gt  click to join us  lt  div gt           lt a id  login  href  javascript void 0    style  display  inline    gt join lt  a gt       lt  div gt      But this doesn t work  Is this possible

Not a direct answer to OP s problem  but it may help you too  You can declare a local variable next to some html inside a scope without trouble    foreach  var item in Model Stuff        var file   item MoreStuff FirstOrDefault          lt li gt  lt a href   item Source  gt  file Name lt  a gt  lt  li gt

If you want a variable to be accessible across the entire page  it works well to define it at the top of the file   You can use either an implicit or explicit type             implicit type     var something1    quot something quot           explicit type     string something2    quot something quot       lt div gt  something1 lt  div gt    display first variable    lt div gt  something2 lt  div gt    display second variable

I think you were pretty close  try this     bool isUserConnected   string IsNullOrEmpty Model CreatorFullName     if  isUserConnected       meaning that the viewing user has not been saved so continue      lt div gt           lt div gt  click to join us  lt  div gt           lt a id  login  href  javascript void 0    style  display  inline    gt join here lt  a gt       lt  div gt

you can put everything  in a block and easily write any code that you wish in that block just exactly the below code               bool isUserConnected   string IsNullOrEmpty Model CreatorFullName           if  isUserConnected               meaning that the viewing user has not been saved              lt div gt                   lt div gt  click to join us  lt  div gt                   lt a id  login  href  javascript void 0    style  display  inline    gt join lt  a gt               lt  div gt                    it helps you to have at first a cleaner code and also you can prevent your page from loading many times different blocks of codes

If you re looking for a int variable  one that increments as the code loops  you can use something like this        int counter   1     foreach  var item in Model Stuff            some code         counter   counter   1

I think the variable should be in the same block        bool isUserConnected   string IsNullOrEmpty Model CreatorFullName       if  isUserConnected           meaning that the viewing user has not been saved          lt div gt               lt div gt  click to join us  lt  div gt               lt a id  login  href  javascript void 0    style  display  inline    gt join lt  a gt           lt  div gt
