程序写日志进行保存记录调试

//保存当地文本格式.txt
WriteFile("1:name" + name);

public static void WriteFile(string content)
{
    string Filepath = "C:\log\";
    string FileName = DateTime.Now.ToString("yyyy-MM-dd") + "_log.txt";
    if (!File.Exists(Filepath))
    　　Directory.CreateDirectory(Filepath);
　　File.AppendAllText(Filepath + FileName, content + " 
 ", Encoding.GetEncoding("utf-8"));
}    

windows程序

public static void WriteFile(string content)
        {
            string haarXmlPath = "log\" + DateTime.Now.ToString("yyyy-MM-dd") + "_log.txt";
            string strFileName = Application.StartupPath.Substring(0, Application.StartupPath.LastIndexOf("\"));
            strFileName = strFileName.Substring(0, strFileName.LastIndexOf("\")) + "\" + haarXmlPath;


            if (File.Exists(strFileName))
            {
                //File.Delete(pathWrite);
            }
            File.AppendAllText(strFileName, content ,
                Encoding.GetEncoding("utf-8"));
        }
