C # keyvaluepair usage. Struct, which defines key/value pairs that can be set or retrieved. That is to say, we can use it to record a key/value pair. For example, if we want to define a key/value pair such as ID (INT type) and name (string type),

"%" Is the remainder. Needless to say. "/": The integer operation is an integer operation, and the floating point operation is a division operation. For example, the result of 54/10 is 5, the result of 54.0/10.0 is 5.4, and only the integer part is

When I learned C # in the early stage, I often encountered the following statements: Public String studentname { Get {return stuname ;} Set {stuname = value ;} } I didn't quite understand why? After learning C #, I cannot make a summary of it. Today

Suppose a static bool g_test = false is defined in test. h; If both test1.c and test2.c contain test. H, test1.c and test2.c generate two g_test copies respectively, and set g_test = true in test1.c, while the value of false in test2.c remains

These macros are used for Conditional compilation. Generally, all the rows in the source program are compiled. However, sometimes you want to compile a part of the content only when certain conditions are met, that is, to specify the compilation
