我建了一个项目luyin1
在此项目里添加了一个类Ｄ１６０A ,　内容如下:

我现在又在项目里加了一个类Class2，在Class2中需要调用类D160中的放音函数应该怎么实现呢？

luyin1.D160A.方法名

给你一个例子

[QUOTE]using System;
namespace *****.USB
{
/// <summary>

string temp=Convert.ToString(b,16)+Convert.ToString(a,16);
return temp=temp.ToUpper();
}
}
}[/QUOTE]

楼上的大虾,小弟实在太小白了,看了你的例子有些不明白的地方还望大虾们指点迷经的说

// public static void Main()
// {
// GetNumberString();
// }
楼上把这三句注释了那程序的入口在那里呢?


string temp=Convert.ToString(b,16)+Convert.ToString(a,16);
return temp=temp.ToUpper();
这两句是什么意思呢?

这个例子是从USB里读出一段信息
即是 sn_0,sn_1然后赋予 a 和 b
前面调用了动态链接库之后声明其内的函数和接口类型
然后下面我写了一个方法就是GetNumberString
如果你想在这个类里调用的话就把注释去掉
在方法前加static 这样就可以执行了
在这里是打印控制台信息以检查读取的是否正确用的
检查后我把它注释掉了
因为实际运用的时候不用输出的
如果你不在这个类里用的话
就把Main注释掉然后在其他类中声明实例然后调用这个方法就行了

至于后面那2行
string temp=Convert.ToString(b,16)+Convert.ToString(a,16);
return temp=temp.ToUpper();
Convert是一个转换类 把后面的东西转换为一个串
因为a和b 读出来的时候是数字类型 16的意思是转换成16进制的串

总体功能就是从USB读取其序列号

[此贴子已经被作者于2006-8-10 16:38:06编辑过]

會又默認入口的
都是static方法 入口搞為private


應該把b和a轉為16進制的string吧

返回temp的大寫

哦,终于了了!

谢谢两位大虾

我根据上面的类D160A又写了一个类CLass2　内容如下：

public class Class2

}
short TotalLine;

break;

}


可调试的时候显示找不到TotalLine　Lines　那里又出错了呢？高手们帮帮忙啊！

那2个变量声明都是在一个方法内的
作用范围应该局限于那个方法
外方法是无法掉用的
你得把声明提到外边去

我把声明提到外面去了,可调试时又显示非静态的字段 方法 或属性"luyin1.Class2.Lines"要求对象引用

还有就是在主程序里调用方法时只有www方法没有DoWork方法


怎么办？郁闷中．．．．
