请有人帮助我！我不知道为什么但是Directory.GetFiles看起来不起作用。我查看了var myLyndaFiles通过断点，但我得到它或多或少为零[0] - ＆gt;但那里有20多个文件...

Answer 1

应该是（在你的扩展文件上添加通配符）：

 var myLyndaFiles = Directory.GetFiles(tbxFrom.Text, "*.lynda");
 var lynda = Directory.GetFiles(tbxProgrammLocation.Text, "*.exe");

而不是：

 var myLyndaFiles = Directory.GetFiles(tbxFrom.Text, ".lynda");
 var lynda = Directory.GetFiles(tbxProgrammLocation.Text, ".exe");

为什么它没有按预期工作？
