通常 object 到 string 有四种方式(假设有object obj):obj.ToString().Convert.ToString().(string)obj.obj as string.他们都能将 object 对象转换成 string 对象.我就讲讲他们的异同以及在实际中应该使用哪个. 前两个方法通常是由别的对象得到 string 对象,它们间的区别只表现在要转换的对象为 null 时,如果 obj 为 null,调用 obj.ToString 方法会导致 NullReferen…

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.ToInt32()和int.Parse()的细微差别: 对于空值(null)的处理不 同,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…
