                {
                    string[] keyvalue = _line.Split('\\');
                    if (keyvalue.Length == 2)
                    {
                        _werFileContent.Add(keyvalue[0], keyvalue[1]);
                    }
                }

            }
        }

推荐答案

如果查看第二张图片，在底部的Autos中可以看到字典为空（Count = 0）;

If you look at the second pic, in the Autos at the bottom you can see that the dictionary is empty (Count = 0);

您能告诉我们您要阅读的文件吗？

Can you show us the file you are trying to read?
