我在使用System.Threading.Tasks.Parallel.ForEach时遇到问题.身体foreach progressBar想要更新.但Invoke方法有时会冻结.
我将代码附加到prograssbar和Buton的表单中.
private void button1_Click(object sender, EventArgs e)

private void pforeach()
{
int[] intArray = new int[60];
int totalcount = intArray.Length;
object lck = new object();
System.Threading.Tasks.Parallel.ForEach<int, int>(intArray,

int value = 0;
System.Threading.Thread.Sleep(100);
count++;
value = (int)(100f / (float)totalcount * (float)count);
Set(value);
return count;
},
(x) =>

}
private void Set(int i)
{
