Visual Studio C# 不识别右大括号

Question

I'm working with Visual Studio, making a .CSHTML web page. The code was working code. Through some unknown edit? or bug?(unlikely) Visual studio will not recognize the last set of {}. The ones that start with @{ C# code here

}

Compiler Error: "Parser Error Message: The code block is missing a closing "}" character. Make sure you have a matching "}" character for all the "{" characters within this block, and that none of the "}" characters are being interpreted as markup.

Source Error:

Line 2:
Line 3:
Line 4: @{ Line 5: var db = Database.Open("DevDbCS"); Line 6:
"

I have copy and pasted my code to notepad ++ that highlights the corresponding bracket if I select one. I have confirmed that all brakes open and close correctly. I even dropped it into Processing, (wont compile) but it says all good too.

When it gets to my !DOCTYPE html it tells me "The type or namespace name 'DOCTYPE' could not be could not be found....) Likely because it cant figure out where the closing brace is.

Where have I gone wrong? It is very frustrating that the compilers message isnt being helpful because all the braces are correct!

Answer 1

try to remove the opening parenthesis between the equal sign and the db variable in this line:

var RecordCount2 = (db.Query ....

This doesn't have a matching closing parenthesis. Because of that the compiler can't match the curly braces afterwards to the opening ones and shows a misleading error
