winform,xml读取与写入

创建两个xml文件，一个 xml做为模板配置项，另一个做为临时接收数据。

private static string localPath = System.Environment.CurrentDirectory + @"\test\";

private static string localPathOld = System.Environment.CurrentDirectory + @"\test\YUYUE_PRINTOld.xml";
private static string localPathAdd = System.Environment.CurrentDirectory + @"\test\YUYUE_PRINT.xml";

写入方法：

string path = localPath + "/YUYUE_PRINTOld.xml";

string stu_At= "{'name': '0000899112','BarcodeRecognition': 'UPC-E','Sex': '男','Age': '27','Blood': '全血','BarCode': '210720002147','Content': '网织红细胞计数','iMode': 0}";
var docment = CustomerFormBase.Json2Xml(stu_At);
docment.Save(path);

xml读取方法：
