如果文件不是多线程写入,用这个写入比较方便,不用引用第三方库,如果是高频写日志建议用Log4net,相关的log4net方法请访问C#, .Net添加log4net日志功能-罗分明网络博客 (luofenming.com)
/// <summary>
/// 写日志方法
/// </summary>
/// <param name="pathStr">日志存放位置</param>
/// <param name="msg">日志内容</param>
public void WriteLog(string pathStr, string msg)
{
string tempPath = Path.GetDirectoryName(pathStr);//获得文件的目录
if (!Directory.Exists(tempPath))//如果没有文件指定的目录就创建
{
Directory.CreateDirectory(tempPath);
}
using (StreamWriter sw = new StreamWriter(pathStr, true))
{
sw.Write(msg);
}
}
/// <summary>

public string ReadLog(string pathStr)
{
if (File.Exists(pathStr))
{
using (StreamReader sr = new StreamReader(pathStr, true))
{
return sr.ReadToEnd();
}
}
return string.Empty;
}方法调用
string path = AppDomain.CurrentDomain.BaseDirectory + "/temp/1.txt"; WriteLog(path, "测试写入文件"); string s = ReadLog(path);
