Core sample code:

C # code  

1. // Create an xmlDocument
2. XmlDocument doc = new XmlDocument ();
4. // Create a claim segment, as shown in <? Xml version = "1.0" encoding = "UTF-8"?>
5. Doc. AppendChild (doc. CreateXmlDeclaration ("1.0", "UTF-8", null ));
6. // Create a root node KYTResults
7. XmlElement results = doc. CreateElement ("KYTResults ");
9. // Create ResultsStatus
10. XmlNode resultsStatus = doc. CreateElement ("ResultsStatus ");
11. // Create a Level
12. XmlElement element = doc. CreateElement ("Level ");
13. Element. InnerText = status? "0": "1 ";
14. ResultsStatus. AppendChild (element );
15. // Create Description
16. Element = doc. CreateElement ("Description ");
17. Element. InnerText = msg;
18. ResultsStatus. AppendChild (element );
19. // Create a PassKey. If the user fails to log on, an empty character will be loaded.
20. Element = doc. CreateElement ("PassKey ");
21. Element. InnerText = key;
22. ResultsStatus. AppendChild (element );
23. Results. AppendChild (resultsStatus );
24. // END creates ResultsStatus
26. // Create a DataList data set
27. If (status)
28. {
29. Results. AppendChild (dataList );
30. }
31. // END creates a root node KYTResults
32. Doc. AppendChild (results );
35. String path = Server. MapPath ("/ws/xsd/ReceiveReturn. xsd ");
37. // Verify that the xml format has passed xsd Verification
38. String error = "";
39. // Declare XmlSchema
40. XmlSchemaSet schemas = new XmlSchemaSet ();
41. Schemas. Add ("", XmlReader. Create (path ));
42. // Declare the event handling method
43. ValidationEventHandler eventHandler = new ValidationEventHandler (delegate (object sender, ValidationEventArgs e ){
44. Switch (e. Severity)
45. {
46. Case XmlSeverityType. Error:
47. Error + = e. Message;
48. Break;
49. Case XmlSeverityType. Warning:
50. Break;
51. }
52. });
53. Doc. Schemas = schemas;
54. // Verify xml
55. Doc. Validate (eventHandler );
56. // Check whether there is any exception. If the format is incorrect, it will be thrown out.
57. If (! "". Equals (error ))
58. {
59. Throw new Exception (error );
60. }

In the C language, what is the symbol (->) and how to use it?

This is a symbol in the struct pointer. Write a program to explain it, for example:
# Include <stdio. h>
Struct STU // define a struct
{
Int num;
} Stu;
Int main ()
{
Struct STU * p; // defines a struct pointer.
P = stu; // p points to the struct variable stu.
Stu. num = 100; // attaches an initial value to the struct member num.
Printf ("% d", p-> num); // output the num value in stu
Return;
}
As you can see, the-> method is to reference the variable in the struct !!
Format: p-> struct member (such as p-> num)
The function is equivalent to stu. num or (* p). num.
I don't know. You don't understand, and don't understand call me. O (∩ _ ∩) O ~
Hope to adopt it.
