文件测试没有扩展和我需要帮助来移动或用此文件的东西有扩展

The file test has no extension and I need help to either move or rename this file to something with a extension

推荐答案

没有扩展名的对功能无影响。
此外，重命名为真正的变相刚刚一动，所以你想要做的就是

Having no extension has no bearing on the function.Also, a rename is really just a move "in disguise", so what you want to do is

File.Move(@"C:\Users\Username\Desktop\test", @"C:\Users\Username\Desktop\potato.txt")

请承担@，因为你也没能逃脱反斜线。

Please bear in mind the @ before the string, as you haven't escaped the backslashes.
