Print code behind function return value in aspx page

问题

I'm sure this is trivial, but why isn't the Windows Authentication user printing in my ASP.NET page inline?

Code behind function:

public string GetCurrentUserWindowsLogin()
{
    string windowsLogin = Page.User.Identity.Name;
    int hasDomain = windowsLogin.IndexOf(@"\");
    if (hasDomain > 0)
    {
        windowsLogin = windowsLogin.Remove(0, hasDomain + 1);
    }
    return windowsLogin;
}

Inline code:

<div class="loginDisplay">[ <%#GetCurrentUserWindowsLogin() %> ]</div>

回答1:

The <%#... %> is used for Binding Expressions like Eval and Bind.

So if you call Page.DataBind() in page_load it should work.

Another way that should work is to use code render blocks which run normal code:

<% GetCurrentUserWindowsLogin() %>

or the <%= %> construct used for small chunks of information:

<%= GetCurrentUserWindowsLogin() %>

回答2:

Just a follow up on the above answer, the <%= is like response.write.
