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();
        }
    }
}
