C# WinForm 类和form，form和form间怎样传值通信？

如果ClientHandler 是你自己实现的就好办，你在这个类里面public string Message保存字符串，在你接收到消冲陵息后散蔽戚把消息赋值给Message

然后在你声明bootstrap上面声明

var client=new ClientHandler()

...其它代码

pipline.AddLast(client)

这样在接收到消息之后，你直接访问client.Message里面就有你要的消息并毁

这种写法你看一下

const int WM_COPYDATA = 0x004A

[DllImport("User32.dll", EntryPoint = "SendMessage")]

private static extern int SendMessage(

int hWnd, // handle to destination window

int Msg, // message

int wParam, // first message parameter

ref COPYDATASTRUCT lParam /耐老森/ second message parameter

)

[DllImport("User32.dll", EntryPoint = "FindWindow")]

private static extern int FindWindow(string lpClassName, string

lpWindowName)

private void button1_Click(object sender, EventArgs e)

{

int WINDOW_HANDLER = FindWindow(null, "指南针优化软件")

if (WINDOW_HANDLER == 0)

{

Process p = new Process()

p.StartInfo.FileName = Application.StartupPath + "\\..\\ZNZ.exe"

p.Start()

Application.Exit()

}

else

{

byte[] sarr = System.Text.Encoding.Default.GetBytes(this.textBox1.Text)

int len = sarr.Length

COPYDATASTRUCT cds

cds.dwData = (IntPtr)100

cds.lpData = this.textBox1.Text

cds.cbData = len + 1

SendMessage(WINDOW_HANDLER, WM_COPYDATA, 0, ref cds)

}

}

public struct COPYDATASTRUCT

{

public IntPtr dwData//用户定义数据

public int cbData//数据昌亩大小含带

[MarshalAs(UnmanagedType.LPStr)]

public string lpData//指向数据的指针

}
