is called, the contents of the StringBuffer object also change, for example:stringbuffer sb = new StringBuffer ("abc");Sb.append (true);The value of the object SB will become "Abctrue". using this method to concatenate strings will save more content than string, such as a connection applied to a database SQL statement, such as:stringbuffer sb = new StringBuffer
Recently, the project needs to simulate a form in winform to submit data to the server. It is easy to submit key-value pairs separately and upload files separately. It is troublesome to submit both key-value pairs and files. Baidu Google has never had any gains for a long time. In desperation, follow the idea of "Black Moon. Net" to write it by yourself. After hard work, we finally got it done.The method is as follows:
Public webresponse submitdata (string filename, Uri, string [] keys, string
bytes, because K is aligned on the 4-byte boundary. Because the maximum alignment value of SA members is 4, the entire structure is also 4 bytes aligned. Therefore, the last four digits of the address can be divisible by four.4.2 nested struct membersLet's look at an example:# Include "stdio. h"Struct sb{Int C;Double K;Short B;};Struct SA{Char g;Sb B;Char K;};Int main (INT argc, char * argv []){Sa;Printf (

1, the page is less than or equal to 1 o'clock does not show;
2, the number of pages greater than 10 o'clock, automatically shortened.
The specific code is as follows:
