读取本地json文件,转出为指定格式json 使用Base64进行string的加密和解密

读取本地json文件,转出为指定格式json

 

引用添加Json.Net

引用命名空间 using Newtonsoft.Json

//读取自定目录下的json文件
StreamReader sr = new StreamReader(@"D:\xxx.json");
string json = sr.ReadToEnd();
//json文件转为 对象  T 创建的类 字段名 应该和json文件中的保持一致     
var data = JsonConvert.DeserializeObject<T>(json);

//对读出的data进行转换 ,获得新的newData

//

//转换为指定格式的json
var json1 = Newtonsoft.Json.JsonConvert.SerializeObject(newData);
//写入到指定文件中
StreamWriter sw = new StreamWriter(@"D:\new.json");
sw.Write(json1);
sw.Flush();
sw.Close();

----

使用Base64进行string的加密和解密

 

//字符串转bytes
var ebytes = System.Text.Encoding.Default.GetBytes(keyWord);
//bytes进行base64加密
var strBase64 = Convert.ToBase64String(ebytes);

//base64字符转bytes
var dbytes = Convert.FromBase64String(strBase64);
////bytes进行解密为原始字符串
var str = System.Text.Encoding.Default.GetString(dbytes);

//js中加密方法

var base64EncodeChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
