MonoDevelop/MonoTouch - 表達式表示'值'，其中'方法組'是預期的 - 無法找到錯誤信息

Question

在Tasky應用程序的核心之後，我創建了業務層和數據庫層，但是當嘗試編譯時，錯誤：

Error CS0119: Expression denotes a 'value', where a 'method group' was expected (CS0119) (assales.core) 

的問題是，有沒有行號，也沒有文件參考與這些錯誤走的通常會用一個編譯錯誤發生。這讓我想到或許項目選項存在問題，但這只是一個猜測，而且有很多選擇。我需要做什麼來找到錯誤或獲得有關此錯誤的更多信息。

我認爲這是單聲道的編譯器的問題。如果我忽略在聲明中使用了「新」的關鍵字變種：

 
// "var" version 
public class App { 
    public static void Main() { 
     //missing keyword "new" 
     var bitArray = System.Collections.BitArray(); 
    } 
} 

編譯器不顯示行數或者文件名：

 
$ mcs App.cs 
error CS0119: Expression denotes a `type', where a `variable', `value' or `method group' was expected 

相反，如果我宣佈明確bitArray（不使用「 VAR「）：

 
public class App { 
    public static void Main() { 
     //missing keyword "new" 
     System.Collections.BitArray bitArray = System.Collections.BitArray(); 
    } 
} 

編譯器效果很好：

 
$ mcs App.cs 
App.cs(3,27): error CS0119: Expression denotes a `type', where a `variable', `value' or `method group' was expected 
was expected 

我的MCS的版本是：

$mcs --version 
Mono C# compiler version 3.2.3.0 

順便說一句，微軟編譯器效果很好也App.cs

/cygdrive/c/WINDOWS/Microsoft.NET/Framework/v4.0.30319/csc.exe App.cs 
Microsoft (R) Visual C# 2010 Compiler version 4.0.30319.1

App.cs(4,23): error CS0119: 'System.Collections.BitArray' is a 'type', which is not valid in the given context
