出错的地方在写入之前无法终止进程,说进程还是被另一个使用,希望大家帮忙解决一下,本人菜鸟,刚接触C#,希望各位大虾不要写的太难,最好带注释.谢谢了.

Answer 1

if (di.Exists)
                {
                    Console.WriteLine("已存在Log目录");
                    return;
                }

Answer 2

这跟加不加return没有关系,不信你也可以试试,最后还是文件被进程占用.

Answer 3

if (di.Exists)
                {
                    Console.WriteLine("已存在Log目录");
                }
                else
                {
                    Console.WriteLine("不存在Log目录");
                    di.Create();
                    Console.WriteLine("目录已创建");
                }

Answer 4

一样的,这个不是放进else里面就能解决的.而是创建完目录以后又创建文本文件,然后从控制台输入字符串写入这个文本文件里.现在的错误是,创建完文本文件就一直在使用着,无法再打开，说进程正在被使用.麻烦各位帮我解决.说的我听不懂,代码搞定,谢啦.
