读取Json文件
public string input_file; //json文件路径
private string user_id ;
private void Read()
{
if (!File.Exists(input_file)) //判断文件是否存在
{
return；
}
try
{
StreamReader sr = new StreamReader(input_file, Encoding.UTF8);
string json = sr.ReadToEnd();
JsonData jd = JsonMapper.ToObject(json);
StaticClass.user_id = jd["user_id"].ToString(); //键对值赋值
}
catch
{
}
}
保存Json文件
public string output_file //json文件路劲
public void Save()
{
//判断文件是否存在
if (!File.Exists(output_file))
{
FileStream fs = File.Create(output_file);//创建json文件
fs.Close();
}
else
{
File.Delete(output_file);//删除旧文件
FileStream fs = File.Create(output_file);//重新创建
fs.Close();
}
StringBuilder sb = new StringBuilder();
JsonWriter jw = new JsonWriter(sb);
jw.WriteObjectStart();
jw.WritePropertyName("user_id");
jw.Write(StaticClass.user_id);
jw.WritePropertyName("score");
jw.Write(StaticClass.score);
jw.WritePropertyName("time");
jw.Write(StaticClass.time);
jw.WriteObjectEnd();
//StreamWriter sw = new StreamWriter(output_file, false, Encoding.UTF8);//有BOM标签
StreamWriter sw = new StreamWriter(output_file, false, new UTF8Encoding(false));//没有标签
sw.Write(sb);
sw.Close();
