C#判断是否运行在调试模式下

很多情况下我们希望一些调试信息不输出，但又不至于用到trace和debug的一些功能，仅仅是包一下几句话，非调试状态就不运行，有这些用法

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 

          '调试状态下运行 
                Else 

#End   If
