In C #, uint-byte []-Char []-string mutual conversion Summary

Uint ----- byte [] ----- char [] ----- string

 

Some types of mutual conversion are often required for some interoperability. For example, when using C # To access WIN32API, you often need to input the DWORD parameter to the API: the data represented by the uint value may need to be displayed as characters in actual application, but the relationship between C # APIs cannot be compared with that of C ++, therefore, it is necessary to convert some data types in C,
Some simple conversion operations are pasted below to facilitate memory

Uint ---> byte []

Byte [] bpara= System. bitconverter. getbytes (uint upara );

 

Byte [] ---> uint

Uint upara = system. bitconverter. touint32 (bpara );

 

Byte ---> char

System. Convert. tochar (bpara );

 

Char ---> byte

System. Convert. tobyte (cpara );

 

Byte [] ---> char []

(1) Char [] cpara = system. Text. encoding. Default. getchars (bpara); (1)

(2) Char [] cpara = new char [bpara. Length];

For (INT I = 0; I <bpara. length; I ++) {char [I] = system. Convert. tochar (bpara [I]);}

(3)Char [] cpara =New asciiencoding (). getchars (bpara );

 

Char [] ---> byte []

(1)Byte [] bpara = system. Text. encoding. Default. getbytes (cpara );

 (2)Byte [] bpara = New asciiencoding (). getbytes (cpara );

Char [] ---> string

String spara = new string (cpara );

 

String --- char []

Char [] cpara = spara. tochararray ()

Uint ----> char []

 (1) uint --> byte [];

(2) byte [] --> char [];

Uint ---> string

(1) uint --> byte [];

(2) byte [] --> char [];

(3) Char [] --> string;

 

Byte [] ---> string

(1). byte [] --> char [];

(2). Char [] --> string;

(3) New asciiencoding (). getstring (bprar );

Char [] ---> uint

(1). Char [] --> byte [];

(2). byte [] --> uint;

String ---> byte []

Bpara = system. Text. encoding. Default. getbytes (spara)

 

String ---> uint

(1) string --> byte [];

(2) byte [] --> uint;

 

Note that when interacting with APIs using uint characters, you must pay attention to the character sequence, which involves the issue of API high/low data, that is, the data obtained from dowrd In the API is usually in reverse order in the C # representation, therefore, when getting or passing strings in C #, you must pay attention to reverse processing before conversion to uint for API use. You have the opportunity to summarize and paste it.
