多线程访问窗体控件出错
哪位老师教我！谢谢！
delegate void SetTextCallback1(string test);
public void TestClass(string test)
{
if (this.textBox2.InvokeRequired)
{
SetTextCallback1 a = new SetTextCallback1(TestClass);
this.Invoke(a, new object[] { test });
}
else
{
for (int i = 0; i < 100; i++)
{
this.textBox2.Text +=test+ "\r\n ";
}
}
}
public void TestClass1()
{
if (this.textBox1.InvokeRequired)
{
SetTextCallback d = new SetTextCallback(TestClass1);
this.Invoke(d, new object[] {});
}
else
{
for (int i = 0; i < 500; i++)
{
this.textBox1.Text += DateTime.Now.ToString( "yyyy年MM月dd日 ") + "\r\n ";
}
}
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
Thread thd1 = new Thread(new ThreadStart(TestClass));//在这里出错，“TestClass”的重载均与委托“System.Threading.ThreadStart”不匹配
Thread thd2 = new Thread(new ThreadStart(TestClass1));
thd1.Start();
thd2.Start();
}
[解决办法]
delegate void SetTextCallback1(string test);
public void TestClass(string test)
{
if (this.textBox2.InvokeRequired)
{
SetTextCallback1 a = new SetTextCallback1(TestClass);
this.Invoke(a, new object[] { test });
}
else
{
for (int i = 0; i < 100; i++)
{
this.textBox2.Text += test + "\r\n ";
}
}
}
private void button1_Click(object sender, EventArgs e)
{
Thread thd1 = new Thread(new ThreadStart(ProcThreadone));
thd1.Start();
}
private void ProcThreadone()
{
TestClass( "Test Thread ");
}
