我正在使用下一个代码将文本分隔为单词,然后将这些单词插入数据库。
问题是逗号也会被复制。
如何从逗号跳到复制的或其他标点符号?
var str = reader1.ReadToEnd();
string[] words = str.Split(' '); //Insert all the song words into words named string
string constring1 = "datasource=localhost;port=3306;username=root;password=abc";
using (var conDataBase1 = new MySqlConnection(constring1))
{
conDataBase1.Open();
for (int i = 0; i < words.Length; i++)
{
int numberOfLetters = words[i].ToCharArray().Length; //Calculate the numbers of letters in each word
var songtext = "insert into myproject.words (word_text,word_length) values('" + words[i] + "','" + numberOfLetters + "');"; //Insert words list and length into words table
MySqlCommand cmdDataBase1 = new MySqlCommand(songtext, conDataBase1);
try
{
cmdDataBase1.ExecuteNonQuery();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
最佳答案
尝试用以下方法替换拆分行:
char [] separators = new char[] {' ', ',', '/'};
var words = str.Split(separators, StringSplitOptions.RemoveEmptyEntries).ToArray();
您将获得无标点符号的单词。您可以将要删除的其他标点添加到
separators
数组中。我放入空格,逗号和/
