C#多线程 操作UI问题

C# 多线程操作UI的简单写法：Keledo Super Plus 

private TaskScheduler mpr_ts_UIContext;
private void button1_Click(object sender, EventArgs e)
{
progressBar1.Visible = true;
progressBar1.Value = 0; //清空进度条
progressBar1.Maximum = 10000;
// 启动任务线程
Task.Run(() =>
{
for (int int_Index = 0; int_Index < 10000; int_Index++)
{
var ts_Run = Task.Factory.StartNew(() =>
{
progressBar1.Value += 1;
Tb_Text.Text = int_Index.ToString();
if (int_Index == 10000 - 1)
{
progressBar1.Visible = false;
}
}, CancellationToken.None, TaskCreationOptions.None, mpr_ts_UIContext);
// 注意这里要同步等待Task.Factory.StartNew的任务结束
ts_Run.Wait();
}
});
// 异步显示对话框
MessageBox.Show("异步执行...");
}
private void Form4_Load(object sender, EventArgs e)
{
mpr_ts_UIContext = TaskScheduler.FromCurrentSynchronizationContext();
progressBar1.Visible = false;

}
