类库
新建类库 Algorithm,类math2必须用public修饰
区分myfunction与math2的区别
class myfunction//类
public class math2//类库,带public,否则另一类库无法访问
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Algorithm
{
**public class math2//类库,带public,否则另一类库无法访问**
{
//静态类:直接引用、无需实例化
//static public int jiafa(int V)
//普通类:引用时需要实例化
public int jiafa2(int V)
{
int M = 2;
int W = V + M;
return W;
}
//普通类:引用时需要实例化
public int chengfa2(int V)
{
int M = 2;
int W = V * M;
return W;
}
//普通类:引用时需要实例化
public int jianfa2(int V)
{
int M = 2;
int W = V - M;
return W;
}
//普通类:引用时需要实例化
public int chufa2(int V)
{
int M = 2;
int W = V / M;
return W;
}
public static float fValue = 10;
public static decimal dValue2 = 10;
public static int xiancheng12 = 10;
public static int xiancheng22 = 10;
public static int xiancheng32 = 10;
}
}
在主类库OPC_Client中添加引用类库Algorithm
然后在调用类库Algorithm的类文件中Using Algorithm
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
**using Algorithm;**
namespace OPC_Client
{
//class class_var
//{
// public static int Numglobal1;
//}
public partial class ftplt : Form
{
public ftplt()
{
InitializeComponent();
}
private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{

private void button1_Click(object sender, EventArgs e)

frm.Show();
tabControl1.TabPages[btn.Text].Controls.Add(frm);
}
//else if()
//{}
}
tabControl1.SelectedTab = tabControl1.TabPages[btn.Text];
}
private void timer1_Tick(object sender, EventArgs e)
{
//if (myfunction.xiancheng1 < 60)
// myfunction.xiancheng1++;
//else
// myfunction.xiancheng1 = 0;
//lblglobal1.Text = myfunction.xiancheng1.ToString();
if (math2.xiancheng12 < 60)
math2.xiancheng12++;
else
math2.xiancheng12 = 0;

}
}
