[C#] MiniExcel获取表格标题内容

MiniExcel的GetColumns仅返回标题的有效列（如果有5列就返回A,B,C,D,E五个字符），不能给出标题名

稍作修改：

        private static FileStream MiniExcel_OpenSharedRead(string path)
        {
            return File.Open(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
        }
        private static Dictionary<string, object> MiniExcel_GetColumns(string file)
        {
            IDictionary<string, object> dictionary = null;
            using (FileStream fileStream = MiniExcel_OpenSharedRead(file))
            {
                dictionary = fileStream.Query(false, null, ExcelType.UNKNOWN, "A1", null).FirstOrDefault<object>() as IDictionary<string, object>;
            }
            var bbb = dictionary.ToDictionary(x => x.Key, x => x.Value);
            return bbb;
        }

获取标题名时用法如下

var bbb = MiniExcel_GetColumns(file).Values;//获取列名称
