Question

private void button1_Click(object sender, EventArgs e)
        {
            List<string> ncmFile=new List<string>();
            ncmFile.Add("NCM1");
            ncmFile.Add("NCM2");

            List<string> naeFile = new List<string>();
            naeFile.Add("NAE1");
            naeFile.Add("NAE2");


            for (int i = 0; i < ncmFile.Count; i++)
            {
                Thread t = new Thread(new ThreadStart( ()=>NCMNAEConversion(ncmFile[i], naeFile[i])) );
                t.Start();
            }
        }

        public void NCMNAEConversion(string ncmFileName, string naeFile)
        {

            //conversion process
        }

注意：示例代码在上面，我想基于no ncm List同时运行NCM NAEConversion方法。这个线程同时运行吗？

查看Parallel课程： http://msdn.microsoft.com/de-de/library/system.threading.tasks.parallel%28v=vs.110%29.aspx

正如Gdoron所说，没有真正的并行处理，但是这个类CPU将为每个线程分配一段时间，然后步骤到下一个，依此类推......

考虑TPL而不是自己启动线程：

using System.Collections.Generic;
using System.Threading.Tasks;

List<string> ncmFile = new List<string>();
ncmFile.Add("NCM1");
ncmFile.Add("NCM2");

List<string> naeFile = new List<string>();
naeFile.Add("NAE1");
naeFile.Add("NAE2");

Parallel.For(0, ncmFile.Count, (i) =>
{
    string ncm = ncmFile[i];
    string nae = naeFile[i];
    NCMNAEConversion(ncm, nae);
});

我建议使用ThreadPool创建多个线程。

ThreadPool.QueueUserWorkItem(new WaitCallback(NCMNAEConversion), new string[]{ ncmFile[i], naeFile[i]});

public void NCMNAEConversion(object state) 
{ 
    //conversion process
    string[] values = (string[])state;
}

同时启动多个线程
