基本上,我想在FormMain(WindowsForm)上更新ProgressBar UI对象。 我正在使用.NET 4.0
以下是Form1.Designer.cs中的代码:
namespace ProgressBarApp
{
public partial class Form1 : Form
{
private System.Windows.Forms.ProgressBar curProgressBar;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
CustomProcess theProcess = new CustomProcess();
theProcess.Process();
}
}
}
以下是CustomProcess.cs的定义:
namespace ProgressBarApp
{
class CustomProcess
{
public void Process()
{
for (int i = 0; i < 10; i++)
{
Task ProcessATask = Task.Factory.StartNew(() =>
{
Thread.Sleep(1000); // simulating a process
}
);
Task UpdateProgressBar = ProcessATask.ContinueWith((antecedent) =>
{
// how do i update the progress bar object at UI here ?
}
);
}
}
}
}
