step1：定义委托
private delegate void loadingRun(int step);
step2：将对UI的操作封装成方法
private void doUpdate(int step)
{
if (step == 1)
{
this.checkBox1.Checked = true;
this.checkBox1.Font = new System.Drawing.Font("MS UI Gothic", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(128)));
this.checkBox2.Font = new System.Drawing.Font("MS UI Gothic", 12F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(128)));
}
else if (step == 2)
{
this.checkBox2.Checked = true;
this.checkBox2.Font = new System.Drawing.Font("MS UI Gothic", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(128)));
this.checkBox3.Font = new System.Drawing.Font("MS UI Gothic", 12F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(128)));
}
else if (step == 3)
{
this.checkBox3.Checked = true;
this.checkBox3.Font = new System.Drawing.Font("MS UI Gothic", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(128)));
this.checkBox4.Font = new System.Drawing.Font("MS UI Gothic", 12F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(128)));
}
else if (step == 4)
{
this.checkBox4.Checked = true;
this.checkBox4.Font = new System.Drawing.Font("MS UI Gothic", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(128)));
this.Close();
}
}
step3：实例化委托并调用doUpdate
public void run()
{
loadingRun load = new loadingRun(doUpdate);
//do something
this.Invoke(load, 1);
//do something
this.Invoke(load, 2);
//do something
this.Invoke(load, 3);
//do something
this.Invoke(load, 4);
}
step4：让子线程执行run
private void init()
{
ThreadStart ts = new ThreadStart(run);
Thread runThread = new Thread(ts);
runThread.Start();
}
