int i; string s=null; Console.WriteLine(Convert.ToInt32(s)); //值为0 Console.WriteLine(Int.TryParse(s,out i)); //值为true i的值为0 Console.WriteLine(Int.Parse(s)); //抛出异常 注:object obj=123; int item=Convert.ToInt32(obj); 这样得到的item的值为null,而不会为123...
Convert.ToInt32()与int.Parse()的区别,(1)这两个方法的最大不同是它们对null值的处理方法: 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。没搞清楚Convert.ToInt32和int.Parse()的细细微区别时千万别乱用,否则可能会产生无法预料
