一個用C#寫的日志類

在編寫應用程序時，經常會記錄一些日志，於是寫了這個日志類。

功能簡單，不詳述，自己看代碼。

代碼：

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

namespace TagReceiver
{
    class LogHelper
    {
        string logFile = "";
        /// <summary>
        /// 不帶參數的構造函數
        /// </summary>
        public LogHelper()
        {
        }
        /// <summary>
        /// 帶參數的構造函數
        /// </summary>
        /// <param name="logFile"></param>
        public LogHelper(string logFile)
        {
            this.logFile = logFile;
        }
        /// <summary>
        /// 追加一條信息
        /// </summary>
        /// <param name="text"></param>
        public void Write(string text)
        {
            using (StreamWriter sw = new StreamWriter(logFile, true, Encoding.UTF8))
            {
                sw.Write(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss] ") + text);
            }
        }
        /// <summary>
        /// 追加一條信息
        /// </summary>
        /// <param name="logFile"></param>
        /// <param name="text"></param>
        public void Write(string logFile, string text)
        {
            using (StreamWriter sw = new StreamWriter(logFile, true, Encoding.UTF8))
            {
                sw.Write(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss] ") + text);
            }
        }
        /// <summary>
        /// 追加一行信息
        /// </summary>
        /// <param name="text"></param>
        public void WriteLine(string text)
        {
            text += "\r\n";
            using (StreamWriter sw = new StreamWriter(logFile, true, Encoding.UTF8))
            {
                sw.Write(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss] ") + text);
            }
        }
        /// <summary>
        /// 追加一行信息
        /// </summary>
        /// <param name="logFile"></param>
        /// <param name="text"></param>
        public void WriteLine(string logFile, string text)
        {
            text += "\r\n";
            using (StreamWriter sw = new StreamWriter(logFile, true, Encoding.UTF8))
            {
                sw.Write(DateTime.Now.ToString("[yyyy-MM-dd HH:mm:ss] ") + text);
            }
        }
    }
}
