Usually, like in java, any object will implement its to_string() function. So in Plsql, there is the same requirement. We want to implement to_string() in plsql. Thinking When one Object' type is basic type in plsql, then the function will return its value. Otherwise, the function ...
use getChildByName to use an instance name to return a display object: var MC:DisplayObject; function T01MouseDown(event:MouseEvent):void { trace("Tomato 01 Down"); trace(event.target.name); MC = getChildByName(event.target.name); //trace(MC); startX = MC.x; startY = MC.y; event...

1、int适合简单数据类型之间的转换,C#的默认整型是int32(不支持bool型); 2、int.Parse(string sParameter)是个构造函数,参数类型只支持string类型; 3、Convert.ToInt32()适合将Object类型转换为int型; 4、Convert.ToI

the ToString() method of an object returns the type name. so you are building a list of type names. you object appear to ne Copy var fields = new object[] { new string[] {"a","b"}, new int[] {1,2,3} }; as its two arrays of different types, what was the output List<str...
int.Parse是转换String为int; Convert.ToInt32是转换继承自Object的对象为int的; 你得到一个object对象,你想把它转换为int,用int.Parse就不可以,要用 Convert.ToInt32. 总结: (1)Convert.ToInt32的参数比较多,Int.Parse只能转换string类型的. (2)Parse就是把String转换成int,char,double...等,也就是*.Pars...
