1) for converted objects, Convert.ToInt32 () can be of various types (example out of a numeric type outside bool,datetime, etc.), Int. TryParse () and Int. Parse () can only be an integer string type (that is, the form after various integer tostring

One, (int) variable name [coercion type conversion]:This conversion is primarily used for numeric type conversions, from int to long,float,double,decimal types, and implicit conversions are possible, but the use of a long type to an int type

In the previous article, the array name is a constant pointer.Reference: http://blog.pfan.cn/whyhappy/5164.htmlConst int * pi, int const * pi and int * const pi and their operations1 start with const int IYou know, when declaring a variable, int I

I just started seeing this, it hurts.Or do you understand it slowly?First of allvoid (*FUNC) (int) is a pointer to a function with a return value of void parameter intis a function pointerSpecific Understanding Http://zhidao.baidu.com/link?url=5GpEN7

Convert. toint32, Int. parse (int32.parse), Int. tryparse, and (INT) can all be interpreted as converting data types to int. What are the differences between them? Convert. toint32AndInt. parseSimilarly, convert. toint32 actually calls Int. parse:

This problem, sometimes a puzzle, is a time to comb through.Signed char->unsgned char:%c->%c 0->127 (corresponding range)char->int:%c->%d->%c, ' A '->65 (printable Character map)Short int->int:%d->%d,100->100 (corresponding, if the reverse operation

  int I =-1; Int. tryparse (null, out I); after execution, I equals 0 instead of-1. Remember. 1 (INT) is a type conversion. When we convert the NT type to the long, float, double, decimal type, we can use implicit conversion,

int *p () is a function that returns a pointerInt (*p) () is a pointer to a functionfunction that returns the pointer:int * A (int x,int y); There are a number of students (each student has 4 courses), requiring the user to enter the student

1 (INT) is a type conversion. When we convert from int type to long, float, double, decimal type, we can use implicit conversion, however, Explicit conversions are required from the long type to the int type. Otherwise, a compilation error occurs. 2
