ASP.NET how to resolve CS1513: } expected error on page

Question

I am getting an error at run time when viewing my ASP.NET page in the browser. I am not getting any build errors however I am getting the following compiler error at runtime:

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1513: } expected

Source Error:


Line 329:            #line hidden
Line 330:            __output.Write("\r\n\t\t\t</div>\r\n\t\t");
Line 331:        }
Line 332:        
Line 333:        private System.Web.UI.Control __BuildControl__control7() {

Source File: c:\Windows\Microsoft.NET\Framework\v1.1.4322\
    Temporary ASP.NET Files\xxxxxxxx\450ffa78\d46d847d\
    k1gsz9dj.0.cs    Line: 331 

I cannot locate any missing } in my source code and this error is occurring in the generated code files that exist in the Temporary ASP.NET Files directory. How can I trace this to the line of code that is actually malformed in my page or user controls on my page?

Have you tried looking for that .cs file in the folder specified? – Bridgettbridgette

It's on my server, i don't have access to the server. – Kassa

it clearly says "}" is missing check on those lines ... – Mesoblast

I have different user controls called into an aspx page. I can't simply find the line. that is why I am asking that line 333 is part of which user control? how can i tell? – Kassa

Seriously the path given by the debugger is the file you need to open – Bridgettbridgette

That is the file which .NET generates on the fly, so stop suggesting that it says which line you need to find, because it doesn't exist in the source code. – Antonietta

[Edit: See answer post below] – Darksome

Page on Prod site wasn't loading. Dev also failed with an exception that included the file, eg > SourceCode: "#pragma checksum > \"D:\ProjPath\\Views\\Employee\\Details.cshtml\" Cleaned, rebooted, etc to no avail. Commented out the page, ran it successfully, then uncommented section by section until... the whole page ran ok. Schrodinger's Bug, it disappears when you look at it. The punchline? It was then ok on the production server. And no, the data didn't change. All I can come up with is that it had to do with a local browser file or something. – Alten

Answer 1

If the error code related as following:

A variable name same as reserved word then you can rename variable.

A code segment such as:

@model MyModel
{
    var appname = @Model.Apps.FirstOrDefault(x => x.ID == Model.SelectedApp);
}

Remove '@' coming before Model.Apps.FirstOrDefault(x => x.ID == Model.SelectedApp)

A code segment or section usage such as:

@section{ 
    <!-- hiiii it's not about an error -->
}

Remove the apostrophe from comment in section.

If it is none of these specific cases you can attempt to locate where the error is generated by applying a source reduction. Delete/cut/comment out pieces of code until you can reliably turn the error off and on. The code that turns the error on is likely the culprit if it is not one of the above situations.

Encountered this today, my situation was #2 where I had @Model. in a code segment. It seems like as of Razor 2 that the last example with the HTML comment and apostrophe was fixed by the razor generator. I could not reproduce that being an error. – Luggage

Answer 2

Look in the markup (aspx or ascx) for blocks like:

<% ... some C# code.... { %>

   markup(controls, html etc)

<% } %>

Any opened bracket { needs to be closed with another bracket }.

These pages or controls are compiled once by ASP .Net when they are first requested. Visual Studio doesn't compile aspx or ascx files.
If the project is "Web Site" type, Visual Studio compiles the aspx/ascx files, but if the project is "Web Application" type Visual Studio doesn't "compile" the markup (it does not generate the corresponding classes to the aspx/ascx markup)

Robena

It compiles aspx in my experience, but I believe you're right about this being in an ascx – Bridgettbridgette

Answer 3

On my site, the problem was caused by a block of code that looked like this:

            @{  
                var currentNode = @linkedList.Find(@CurrentPage);
                if (@currentNode.Next != null)
                {
                    var next = @currentNode.Next;
                    <li>
                        @next.Name
                    </li>
                }
                if (@currentNode.Previous != null)
                {
                    var prev = @currentNode.Previous;
                    <li>
                        @prev.Name
                    </li>
                }
            }

I'm not sure why the problem was caused by the nesting. This may be a bug in the compiler.

Darksome

I believe the error in your case is var next = @currentNode.Next; and var prev = @currentNode.Previous; both of those are inside of code segments. I believe the razor generator would want var next = currentNode.Next; note the lack of the @ in this line. – Luggage

Answer 4

I got a similar problem and oculd find it only after a log of trial and error.

The error I made was to add a '@' to variables inside a foreach loop which started with:

@foreach

Geniculate

Answer 5

Well as the error suggests, you are missing a closing curly brace '}'

Have a look at the msdn compiler errors documentation:

• http://msdn.microsoft.com/en-us/library/83ht1k63(v=vs.80).aspx

As in the example on MSDN:

// the below will cause CS1513 since namespace is missing '}'
namespace y    
{
   class x
   {
      public static void Main()
      {
      }
   }

but it shouldn't let the thing compile at that point, to get to the point of showing the files in the temporary_files folder – Bridgettbridgette

Answer 6

try to compile it in visual studio. i think it will also show where the exact line of the code that has incomplete curly braces.

compilation error cs1513
