第一种:需要把调试方法改成debug
代码用 #if DEBUG 包裹

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;

namespace SplitPackage
{
  public static class EnvConfig
  {
    static EnvConfig()
    {
#if DEBUG
      ToolsPath = @"D:\workspace\shopstyle\tool";
#else
      ToolsPath = Environment.CurrentDirectory;
#endif
      int rootIdx = ToolsPath.LastIndexOf(@"\");
      if (rootIdx > 0)
      {
        RootPath = ToolsPath.Substring(0, rootIdx);
      }
    }
    public static string ToolsPath { get; private set; }
    public static string TmplateFile { get { return Path.Combine(ToolsPath, @"template\default.pm"); } }
    public static string RootPath { get; private set; }
    public static string ModulePath { get { return Path.Combine(RootPath, "module"); } }
    public static string ConfigPath { get { return Path.Combine(RootPath, "conf"); } }

  }
}

第二种:
利用宏定义

#define DEBUG// C#的宏定义必须出现在所有代码之前。当前我们只让DEBUG宏有效。
using System.Diagnostics;  //必须包含这个包

#define DEBUG

using System.Diagnostics; 

namespace TestConsole
{
  class ToolKit
  {
    [ConditionalAttribute("LI")]       // Attribute名称的长记法
    [ConditionalAttribute("DEBUG")]
    public static void Method1() { Console.WriteLine("Created By Li, Buged.11"); }

    [ConditionalAttribute("LI")]
    [ConditionalAttribute("NOBUG")]
    public static void Method2() { Console.WriteLine("Created By Li, NoBug."); }

    [Conditional("ZHANG")]          // Attribute名称的短记法
    [Conditional("DEBUG")]
    public static void Method3() { Console.WriteLine("Created By Zhang, Buged.11"); }

    [Conditional("ZHANG")]
    [Conditional("NOBUG")]
    public static void Method4() { Console.WriteLine("Created By Zhang, NoBug."); }
  }
    static void Main(string[] args)
    {
      ToolKit.Method1();
      ToolKit.Method2();
      ToolKit.Method3();
      ToolKit.Method4();
    }
  }
}
