使用此代码发现一些错误

_________________________________________________________________

private void过程（）

{

How to enable and disable a button inside of a Thread

i am created a long process inside of a thread, at the same time i want to disable process start button


using this code some errors found
_________________________________________________________________
private void process()
{
btnCreate.Enabled = false; chkGroup.Enabled = false;
//long process
}



______________________On btn Click_________________________________
Thread create = new Thread(process);
create.IsBackground = true;
create.Start();

推荐答案

private void process()
{
btnCreate.Invoke((MethodInvoker) delegate { btnCreate.Enabled = false; chkGroup.Enabled = false; });
//long process
}
 
Thread create = new Thread(new ThreadStart(process));
create.IsBackground = true;
create.Start();

您必须将委托传递给Thread对象，该对象的类型为ThreadStart。然后，要更新UI，您必须使用Control.Invoke方法在UI线程上更新它。

You have to pass a delegate to the Thread object, which is of type ThreadStart. Then for updating the UI you have to update it on the UI thread, using the Control.Invoke method.
