之前unity5.x在代码中写了debug.log..等等，打包之后在当前程序文件夹下会有个对应的"outlog.txt",2017之后这个文件被移到C盘用户Appdata/LocalLow/公司名 文件夹下面。觉得不方便就自己写了个

代码： 

using UnityEngine;

using System.IO;

using System;

using System.Diagnostics;

using Debug = UnityEngine.Debug;

public class DebugTrace

{

    private FileStream fileStream;

    private StreamWriter streamWriter;

    private bool isEditorCreate = false;//是否在编辑器中也产生日志文件

    private int showFrames = 1000;  //打印所有

    #region instance

    private static readonly object obj = new object();

    private static DebugTrace m_instance;

    public static DebugTrace Instance

    {

        get

        {

            if (m_instance == null)

            {

                lock (obj)

                {

                    if (m_instance == null)

                        m_instance = new DebugTrace();

                }

            }

            return m_instance;

        }

    }

    #endregion

    private DebugTrace()

    {

    }
