Data conversion is often used in programming. There are many data conversion methods in C #. There are four methods to convert the target object to an integer (INT: they are (INT) and Int. parse (), Int. tryparse () and convert. toint32 (), What are

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

int i =-1;BOOL B = Int. TryParse (null, out i);When execution is complete, b equals false,i equals 0, not equal to-1, remember.int i =-1;BOOL B = Int. TryParse ("123", out I);After execution, b equals true,i equals 123;1, (int) is a type conversion;

Int. tryparse, convert. toint32, (INT)These types differ in convert when converting the floating point type to an integer. toint32 is rounded to int. tryparse can only be converted to integers, that is, if the floating point type is all, 0 (INT) is

In previous projects, I seldom paid attention to convert, parse, tryparse, Int, and other differences. I found that these details were very important only recently, and I felt that convert, parse, tryparse, and INT were the best way to use them;

Tag: Value log pre throws exception false logs cannot post numberConvert.ToInt32 and Int. The Parse is more similar, in fact Convert.ToInt32 internally called Int. Parse;When the Convert.ToInt32 parameter is NULL, 0 is returned;Int. Throws an

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
