Я пытаюсь получить данные из LinkedIn, а затем сохранить его в базе данных.Как использовать foreach в C#?
Я некоторые проблемы в перекручивание
1.В первый Еогеасп Я вставив данные.
2.Всечение (user_id) ко второй инструкции вставки.
3.Once второй Еогеасп вставить данные, а затем снова я хочу пойти первый Еогеасп
Я написал этот код
public void customerM()
{
XmlDocument d = new XmlDocument();
d.LoadXml(content);
XmlNodeList customer = d.SelectNodes("//posts/post/creator");
foreach (XmlNode cus in customer)
{
user_id = cus["id"].InnerText;
customerFirst_name = cus["first-name"].InnerText;
customerLast_name = cus["last-name"].InnerText;
customerName = string.Format("{0} {1}", customerFirst_name, customerLast_name);
DbConnection.Open();
DbCommand = new OleDbCommand("select count(*) from mw_customer where customer_id='" + user_id + "'", DbConnection);
OleDbDataReader DbReader = DbCommand.ExecuteReader();
while (DbReader.Read())
{
count = DbReader[0].ToString();
cnt = Convert.ToInt32(count);
if (cnt == 0)
{
DbCommand = new OleDbCommand("insert into mw_customer(customer_id,name,first_name,last_name,user_id,cust_date,community) values('" + user_id + "','" + customerName + "','" + customerFirst_name + "','" + customerLast_name + "','" + user_id + "','" + post_timestamp + "','LinkedIn')", DbConnection);
DbCommand.ExecuteNonQuery();
}
else
{
DbCommand = new OleDbCommand("UPDATE mw_customer set name='" + customerName + "',first_name='" + customerFirst_name + "',last_name='" + customerLast_name + "',user_id='" + user_id + "',community = 'LinkedIn',cust_date='" + post_timestamp + "' where customer_id = '" + user_id + "'", DbConnection);
DbCommand.ExecuteNonQuery();
}
}
DbReader.Close();
XmlNodeList title = d.SelectNodes("//posts/post");
foreach (XmlNode post in title)
{
posts = post["title"].InnerText;
post_id = post["id"].InnerText;
string postTimeStamp = post["creation-timestamp"].InnerText;
double postTimeStamp1 = Convert.ToDouble(postTimeStamp);
DateTime post_timestamp1 = new DateTime(1970, 1, 1, 0, 0, 0, 0).AddSeconds(Math.Round(postTimeStamp1/1000d)).ToLocalTime();
post_timestamp = post_timestamp1.ToString("dd-MMM-yy");
DbCommand = new OleDbCommand("select count(*) from mw_post where post_id = '" + post_id + "'", DbConnection);
OleDbDataReader DbReader1 = DbCommand.ExecuteReader();
while (DbReader1.Read())
{
count = DbReader1[0].ToString();
cnt = Convert.ToInt32(count);
if ((cnt == 0) && (posts != ""))
{
DbCommand = new OleDbCommand("insert into mw_post(post_id,customer_id,post,post_date,community) values('" + post_id + "','" + user_id + "','" + posts + "', '" + post_timestamp + "','LinkedIn')", DbConnection);
DbCommand.ExecuteNonQuery();
if (posts.ToUpper().Contains("Personal Loan".ToUpper()))
{
DbCommand = new OleDbCommand("UPDATE mw_post set prod_id = '2',customer_id='" + user_id + "' where post = '" + posts + "'", DbConnection);
DbCommand.ExecuteNonQuery();

DbCommand.ExecuteNonQuery();

Любые идеи? Заранее спасибо.
Я понятия не имею, о чем вы спрашиваете. Что не так? У вас были ошибки? –
У меня нет ошибок, у клиента XmlNodeList У меня 3 записи, я хочу передать user_id в mw_post, тот же user_id вставлен для всех записей в mw_post – user2500094
Попробуйте отладить свою программу и сообщите нам точно, на каком строка кода вы столкнулись с проблемой? и не могли бы вы разместить здесь xml-файл? – Rezoan
