processing convert string to int

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

In C #, what are the differences between (INT), int32.parse (), convert. toint32 (), and int32.tryparse? The Int keyword indicates an integer that is 32-bit. Its. NET Framework type is system. int32.If int32.tryparse () does not throw an exception,

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;

1, int is suitable for conversion between simple data types, the default integral type of C # is int32 (bool type is not supported);2, Int. Parse (String sparameter) is a constructor, and parameter types only support string types;3. Convert.ToInt32 (

As early as a few years before SQL injection went viral, string conversion into integers has been listed as a required operation for every web program. The web program forcibly converts the id and integer equivalent values from get or post into

Convert.ToInt32()与int.Parse()的区别(1)这两个方法的最大不同是它们对null值的处理：Convert.ToInt32(null)会返回0而不会产生任何异常，但int.Parse(null)则会产生异常。这会在某些情景得到应用，举例来说：假如从url中取一个参数page的值，我们知道这个值是一个int，所以即可以用
