c# parallel foreach 循环查找索引
c# parallel foreach loop finding index
我正在尝试读取文本文件中的所有行并计划显示每一行信息。如何找到循环内每个项目的索引?
string[] lines = File.ReadAllLines("MyFile.txt");
List<string> list_lines = new List<string>(lines);
Parallel.ForEach(list_lines, (line, index) =>
{
Console.WriteLine(index);
// Console.WriteLine(list_lines[index]);
Console.WriteLine(list_lines[0]);
});
Console.ReadLine();
another overload Parallel.ForEach
给你索引。
Parallel.ForEach(list_lines, (line, state, index) =>
{
Console.WriteLine(index);
Console.WriteLine(list_lines[(int)index]); // The type of the `index` is Long.
});
