还有个问题!!!为什么我在上面明明定义了count,counttrue,stop...等等,在 static public void IOCPThreadFunction(int iValue)却用不了,要求从新

还有个问题!!!为什么我在上面明明定义了count,counttrue,stop...等等,在 static public void IOCPThreadFunction(int iValue)却用不了,要求从新定意????????????????????????? --------------------编程问答-------------------- 代码太乱，建议减少缩进（2个空格为宜），然后放到［code=C#］...［/code］中。 --------------------编程问答-------------------- 整理代码如下：
using System;
using System.Collections.Generic;
namespace rating
{
public partial class DistancePulse : UserControl
{
double i = 0;
// ...
}
}
然后再贴出来，人家才好帮你看。 --------------------编程问答-------------------- Error 2 An object reference is required for the nonstatic field, method, or property 'rating.DistancePulse.count' C:\Documents and Settings\liaorb\桌面\新建文件夹\Distance_pulse serial\Distance_pulse\DistancePulse.cs 258 8 Distance_pulse

你看看这个吧 对于静态方法能访问什么样的成员 你需要好好了解下
--------------------编程问答-------------------- 怎么减少空格啊???有自动的吗???大虾 --------------------编程问答-------------------- 只能访问静态成员 --------------------编程问答-------------------- 那这个问题怎么解决啊!我去掉static就会没相应....加上又改变不了那些参数......郁闷 --------------------编程问答-------------------- 建议好好看看关于变量和访问和生存周期
补充：.NET技术 , C#
