Question

Here’s the source:

<% string[] roles = ViewData["Roles"] as string[]; 
                   if (roles != null && roles.Length > 0) {%>
            <p>
                <label for="roleName">
                    Role:</label>
                <% foreach (string role in roles) { %>
                <%: Html.RadioButtonFor(m => m.RoleName, role) %>&nbsp; <span>
                    <%: role%></span>
                <% } %>
            </p>
            <%} %>

Here’s my attempt:

 @{
        string[] roles = ViewData["Roles"] as string[]; 
        if (roles != null && roles.Length > 0) {
            <p>
                <label for="roleName">Role:</label>
                foreach (string role in roles) {    
                    @Html.RadioButtonFor(m => m.RoleName, @role)&nbsp; <span>@role</span>
                    }
            </p>
        }
    }

The problem is that at run time I get the following error message:

Compiler Error Message: CS0103: The name 'role' does not exist in the current context

Source Error:

Line 41:                 <label for="roleName">Role:</label>
Line 42:                 foreach (string role in roles) {    
Line 43:                     @Html.RadioButtonFor(m => m.RoleName, @role)&nbsp; <span>@role</span>
Line 44:             </p>
Line 45:         }

Can someone see what’s wrong. I tried but it seems there is something wrong with my attempt. So far I also tried change line 43 to:

@Html.RadioButtonFor(m => m.RoleName, role)&nbsp; <span>@(role)</span>

@Html.RadioButtonFor(m => m.RoleName, role)&nbsp; <span>@role</span>

Both still don’t work 🙁

Answer 1

foreach (string role in roles) {    
    @Html.RadioButtonFor(m => m.RoleName, @role)&nbsp; <span>@role</span>
}

should be

@foreach (string role in roles) {    
    @Html.RadioButtonFor(m => m.RoleName, role) <span>@role</span>
}
