C#像Mysql数据库插入数据

C#出来MYSQL的方法和处理MSSQL方法过程类似，只不过相应命令的前缀SQL换做了MySql

下面的代码写下来做备忘

C# 操作MySql数据库

public static void InsertIntoDataBase(MySqlConnection conn,Theme theme)
{
string sqlcommand = "insert into processedpapers(dc_ID,dc_title,dc_titleTokens,dc_descriptionTokens,dc_len,dc_description)values(@mydcid,@dmydctitle,@mydctitletokens,@mydcdescriptiontokens,@mydclen,@mydcdescription)";
MySqlParameter dc_ID = new MySqlParameter("@mydcid", MySqlDbType.Int32);
dc_ID.Value = theme.dc_ID;
MySqlParameter dc_len = new MySqlParameter("@mydclen", MySqlDbType.Int16);
dc_len.Value = theme.dc_len;
MySqlParameter dc_title = new MySqlParameter("@mydctitle", MySqlDbType.VarChar, 500);
dc_title.Value=theme.dc_title;
MySqlParameter dc_titleTokens = new MySqlParameter("@mydctitletokens", MySqlDbType.VarChar, 500);
dc_titleTokens.Value=theme.dc_titleTokens;
MySqlParameter dc_descriptionTokens = new MySqlParameter("@mydcdescriptiontokens", MySqlDbType.Text);
dc_descriptionTokens = theme.dc_descriptionTokens;
MySqlParameter dc_description = new MySqlParameter("@mydcdescription",MySqlDbType.Text);
dc_description.Value = theme.dc_description;
MySqlCommand cmd = new MySqlCommand(sqlcommand, conn);
cmd.Parameters.Add(dc_ID);
cmd.Parameters.Add(dc_len);
cmd.Parameters.Add(dc_title);
cmd.Parameters.Add(dc_titleTokens);
cmd.Parameters.Add(dc_descriptionTokens);
cmd.Parameters.Add(dc_description);
conn.Open();
try
{
cmd.ExecuteNonQuery();
}
catch (System.Exception e)
{
StreamWriter sw = new StreamWriter("C:\\myerror.txt", true, Encoding.Default);
sw.Write(e.Message);
sw.Close();
//一旦发生错误程序就停止运行，等待用户发现
Console.Read();
}
conn.Close();

}
