我有一个注册页面，当用户单击提交按钮时，注册表中的数据将存储在数据库中。我还需要插入用户创建帐户的日期。如何在我的插入查询中包含“datetime.now”...

下面是我的代码：

private void ExecuteInsert(string streetAdr, string city, string state, int countryID, string zipCode, string TelNum, string FaxNum)
    {
        SqlConnection connectionString = new SqlConnection(GetConnectString());
        try
        {
            connectionString.Open();

            // Insert Address
            string addressQuery = "Insert into Address (StreetAdd, City, State, CountryID, ZipCode, TelNum, FaxNum)" +
                              "VALUES (@stAd, @CityAdr, @StateAdr, @IDcountry, @zCode ,@Tnumb ,@Fnumb)";

            SqlCommand addressCmd = new SqlCommand(addressQuery, connectionString);
            SqlParameter[] address = new SqlParameter[7];

            address[0] = new SqlParameter("@stAd", SqlDbType.VarChar, 100);
            address[1] = new SqlParameter("@CityAdr", SqlDbType.VarChar, 100);
            address[2] = new SqlParameter("@StateAdr", SqlDbType.VarChar, 100);
            address[3] = new SqlParameter("@IDcountry", SqlDbType.Int, 100);
            address[4] = new SqlParameter("@zCode", SqlDbType.VarChar, 100);
            address[5] = new SqlParameter("@Tnumb", SqlDbType.VarChar, 100);
            address[6] = new SqlParameter("@Fnumb", SqlDbType.VarChar, 100);

            address[0].Value = streetAdr;
            address[1].Value = city;
            address[2].Value = state;
            address[3].Value = countryID;
            address[4].Value = zipCode;
            address[5].Value = TelNum;
            address[6].Value = FaxNum;

            for (int i = 0; i < address.Length; i++)
            {
                addressCmd.Parameters.Add(address[i]);
            }
            addressCmd.CommandType = CommandType.Text;
            addressCmd.ExecuteNonQuery();

        }
        catch (Exception ex)
        { 

        }
        finally 
        {
            connectionString.Close();
        }
    }

datetime.now 应该放在哪里？谢谢你..

您需要在数据库中构建一个日期列，并将日期作为参数传递给上面的其他字段，或者在数据库中为该字段提供默认值。

private void ExecuteInsert(string streetAdr, string city, string state, int countryID, string zipCode, string TelNum, string FaxNum)
    {
        SqlConnection connectionString = new SqlConnection(GetConnectString());
        try
        {
            connectionString.Open();

        // Insert Address
        string addressQuery = "Insert into Address (StreetAdd, City, State, CountryID, ZipCode, TelNum, FaxNum, TransactioNDate)" +
                          "VALUES (@stAd, @CityAdr, @StateAdr, @IDcountry, @zCode ,@Tnumb ,@Fnumb, @Date)";

        SqlCommand addressCmd = new SqlCommand(addressQuery, connectionString);
        SqlParameter[] address = new SqlParameter[8];

        address[0] = new SqlParameter("@stAd", SqlDbType.VarChar, 100);
        address[1] = new SqlParameter("@CityAdr", SqlDbType.VarChar, 100);
        address[2] = new SqlParameter("@StateAdr", SqlDbType.VarChar, 100);
        address[3] = new SqlParameter("@IDcountry", SqlDbType.Int, 100);
        address[4] = new SqlParameter("@zCode", SqlDbType.VarChar, 100);
        address[5] = new SqlParameter("@Tnumb", SqlDbType.VarChar, 100);
        address[6] = new SqlParameter("@Fnumb", SqlDbType.VarChar, 100);
        address[7] = new SqlParameter("@Date", SqlDbType.DateTime);

        address[0].Value = streetAdr;
        address[1].Value = city;
        address[2].Value = state;
        address[3].Value = countryID;
        address[4].Value = zipCode;
        address[5].Value = TelNum;
        address[6].Value = FaxNum;
        address[7].Value = DateTime.Now();

        for (int i = 0; i < address.Length; i++)
        {
            addressCmd.Parameters.Add(address[i]);
        }
        addressCmd.CommandType = CommandType.Text;
        addressCmd.ExecuteNonQuery();

    }
    catch (Exception ex)
    { 

    }
    finally 
    {
        connectionString.Close();
    }
}
