C#输出字符串到文本文件中

写个博客记录下，⽅便以后使⽤：

public class WriteHelper {

public static void WriteFile(object data) {

try {

string path = $@\"D:\\TokenLog\\day{DateTime.Now:yyyy-MM-dd}\"; var filename = $\"TokenLog{DateTime.Now:yyyy-MM-dd HH}.txt\"; if (!Directory.Exists(path))

Directory.CreateDirectory(path);

TextWriter tw = new StreamWriter(Path.Combine(path, filename), true); //true在⽂件末尾添加数据

tw.WriteLine($\"----产⽣时间：{DateTime.Now:yyyy-MM-dd HH:mm:ss}---------------------------------------------------------------------\"); tw.WriteLine(data.ToJsonStr()); tw.Close(); }

catch (Exception e) { } } }

public static class Json{

///

public static string ToJsonStr(this object obj) {

return JsonConvert.SerializeObject(obj, new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore }); }}
