未将对象引用设置到对象的实例,怎么解决啊??

未将对象引用设置到对象的实例,怎么解决啊??,第1张

意思是你使用这个对象之前没有将之实例化。

例如:

Label l = new Label;

这个是已经实例化了,可以对其成员进行 *** 作。

注意实例化是调用构造方法要加括号。

如果你是Label。

那下面如果你调用l.Text之类的属性,那就会出现你那个错误。

解决方法:

1、用VS.NET2003或VS.NET2005(主要看这个程序工程,你原来用的是哪一个开发环境了)打开此程序工程。

2、如果点击运行没有错误,及编译后没有产生语法错误,那么就要找到是在哪个功能的哪条语句中出现了上述错误。可在能执行的地方设置断点,逐句运行程序看到哪条语句后不能执行而提示了错误。

3、如果你已经new过了对象,那么看看自己new过的对象是否已经失效,也就是看看定义的对象的作用范围是否合法。

4、并且可以使用右键的快速监测来查看对象。

5、如果是调用了WebServices(及Web服务)那么看看你实例化的WebServices是否存在,并且你是否实例化了WebServices以及是否在程序工程中添加了Web引用,其中的不对称加密解密过程是否正确,是否执行了应该执行的程序代码。

扩展资料:

语言结构:

类:在C#中类的声明与C++和Java很相似。但是,不像C++,C#结构体与类是不支持继承多个父类。但是,与Java相同的是,一个结构体可以实现接口(interface)。Java的关键字import已经被替换成using,它起到了同样的作用。

布尔运算:条件表达式的结果是布尔数据类型,布尔数据类型是这种语言中独立的一种数据类型,从布尔类型到其他类型没有直接的转换过程,布尔常量true和false是C#中的关键字。错误处理:如Java中那样,通过抛出和捕捉异常对象来管理错误处理过程。

内存管理:由底层.NET框架进行自动内存垃圾回收。一个基本的C#类中包含数据成员、属性、构造器和方法。属性可以是静态或实例成员。

接口:是其他类型为确保它们支持某些 *** 作而实现的引用类型。接口从不直接创建而且没有实际的表示形式,其他类型必须转换为接口类型。

1、简短的引证解释:指内容简单,言词不长。阿英 《高尔基和中国济难会》:"我们的党即使有这一材料,也是不容易保存下来的,很可能只剩下我写的这几行简短的记录了。

" 杜鹏程 《在和平的日子里》第六章:"现在你拟几个简短的报告,作为拟发而未发的报告底稿,保存起来。"2、唯美的解释:唯美的意思是追求绝对的美,但真正意义上的唯美并不存在于这个世界。

唯美提倡"为艺术而艺术",强调超然于生活的纯粹美,追求形式完美和艺术技巧。通常,人们认为唯美主义和彼时发生在法国的象征主义或颓废主义运动同属一脉,是这场国际性文艺运动在英国的分支。

所谓"唯美主义",就是以艺术的形式美作为绝对美的一种艺术主张。这里所说的"美",是指脱离现实的技巧美。

3、英语:英语(English)属于印欧语系中日耳曼语族下的西日耳曼语支,由古代从欧洲大陆移民大不列颠岛的盎格鲁、撒克逊和朱特部落的日耳曼人所说的语言演变而来,并通过英国的殖民活动传播到世界各地。根据以英语作为母语的人数计算,英语是最多国家使用的官方语言,英语也是世界上最广泛的第二语言,也是欧盟,最多国际组织和英联邦国家的官方语言之一。

但仅拥有世界第三位的母语使用者,少于官话汉语和西班牙语。上两个世纪英国和美国在文化、经济、军事、政治和科学上的领先地位使得英语成为一种国际语言。

如今,许多国际场合都使用英语做为沟通媒介。英语也是与电脑联系最密切的语言,大多数编程语言都与英语有联系,而且随着网络的使用,使英文的使用更普及。

英语是联合国的工作语言之一。
