C#判斷是否運行在偵錯模式下

很多情況下我們希望一些調試資訊不輸出，但又不至於用到trace和debug的一些功能，僅僅是包一下幾句話，非調試狀態就不運行，有這些用法

using   System.Diagnostics; class   XY {       [Conditional( "DEBUG ")]       public   static   void   DebugLog(string   in_string)       {             Console.WriteLine(in_srting);       }       public   static   int   Main(string[]   in_args)       {               DebugLog( "This   is   a   test ");               return   5;         } } 

 

if   (System.Environment.StackTrace.ToLower().IndexOf( ":line ")> =0)   Console.WriteLine( "debug "); else   Console.WriteLine( "release ");

string   buildtype; try { bool   found   =   Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(DebuggableAttribute),   false).Length   >   0; buildType   =   found   ?   "Debug "   :   "Release "; } catch { buildType   =   " <error> "; }

#If   DEBUG   Then           '調試狀態下運行                 Else #End   If
