C# 靜態函數調用表單控制項

標籤：

回呼函數方法是靜態函數，需要調用表單控制項，賦值或取值。

  定義 public static Form1 mainFrm;   mainFrm = this;

 public partial class Form1 : Form    {        public static Form1 mainFrm;        public Form1()        {            mainFrm = this;            InitializeComponent();        }

 

  public static void WaitCallBackReceiveConnectedInfo(string connecetedIp,string leaveIp)        {           Form1.mainFrm.rtxtMsg.BeginInvoke(new InvokeDelegate(InvokeMethod), new object[] { connecetedIp, leaveIp });                   }        public delegate void InvokeDelegate(string connecetedIp, string leaveIp);        public static void InvokeMethod(string connecetedIp, string leaveIp)        {            if (connecetedIp != "")            {                Form1.mainFrm.cmbConnectedIP.Items.Add(connecetedIp);                Form1.mainFrm.rtxtMsg.AppendText(connecetedIp+" 串連上來\r\n");                Form1.mainFrm.cmbConnectedIP.SelectedIndex = 0;            }            if (leaveIp != "")            {                Form1.mainFrm.cmbConnectedIP.Items.Remove(leaveIp);                Form1.mainFrm.rtxtMsg.AppendText(leaveIp + " 離開\r\n");            }                   }
