Question

我在创建一个读取和写入excel文件的类时遇到问题。我需要从文件中读取数据（只有一列）。然后我需要搜索方括号[]和/或括号（）的字符串输入。如果该行包含那些，我需要获取其中的信息并通过正斜杠（/）分隔（拆分）答案。我一直在变量上遇到错误。有人能指出我正确的方向吗？谢谢！

            //make connection to document
            var fileName = string.Format("C:/Users/kbangert/Desktop/Karpel/ChargeLanguage.xlsx", Directory.GetCurrentDirectory());
            var connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", fileName);

            //first query to document
            var adapter = new OleDbDataAdapter("SELECT * FROM [ChargeLanguage] WHERE [description] != string.Empty", connectionString);
            var ds = new DataSet();
            adapter.Fill(ds, "descriptions");

            //DataTable data = ds.Tables["descriptions"];
            var data = ds.Tables["descript"].AsEnumerable();

            if (data != null)
            {
                var entry = data.ToString();
                var pattern = @"\[(.*?)\]";
                var matches = Regex.Matches(entry, pattern);

                foreach (Match m in matches)
                {
                    Console.WriteLine(m.Groups[1]);
                }

                string[] words = matches.Split('/');
                foreach (string word in words)
                {
                    Console.WriteLine(word);
                }
            }

在这一行

string[] words = matches.Split('/');

matches是Match个对象的集合。那方面没有Split方法。

你可能想这样做：

foreach (Match m in matches)
{
    Console.WriteLine(m.Groups[1]);

     string[] words = m.Groups[1].Value.Split('/');
     foreach (string word in words)
        Console.WriteLine(word);
}

C＃读取和写入excel文件
