t[i] = Task.Factory.StartNew((p) => { txtDeal(path, p); }, i);

兄弟，是不是哪个地方搞错了

[以专业开发人员为伍]

         for (int i = 0; i < num; i++)
{
    var j = i;

[以专业开发人员为伍]

for (int i = 0; i < num; i++)
{
    var j = i;

引用 5 楼 sp1234 的回复:

for (int i = 0; i < num; i++)
{
    var j = i;

声明个J不知做什么，这和哪个p有联系吗，是不是笔误？

[俺老刘]

         for (int i = 0; i < num; i++)
            {
                string path = txtFrom.Items[i].ToString();
                txtDeal(path, i);

               // t[i] = Task.Factory.StartNew(delegate { txtDeal(path,i); });
            }

主要是那个Tast没用对 如果不用的话就没问题
