double qoutes dans la chaîne de requête sql

Question

Lorsque vous tentez de créer une chaîne pour contenir la requête suivante pour l'importation d'un fichier CSV dans MySQL, la requête elle-même freine la chaîne que j'essaie de créer.

string Query = "load data local infile" + " " + "'" + Filename + "'" + " " + "into table" + " " + Table + "'FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES"; 

Y at-il quelque chose que je fais partie de la ENCLOSED BY '"'?

Merci

Résolution du problème par la méthode suivante si cela aide quelqu'un.

public static void MySqlCSVImport(string Filename, string Table, string Server, string Database, string User, string Password, string Port) 
     { 
      try 
      { 
       //enclosed by '"' 
       string FixFilePath = Filename.Replace(@":\", ":\\"); 
       string c = "'" + "\\n" + "'"; 
       string d = ";"; 

       string connectionString = "server=" + Server + ";database=" + Database + ";User Id=" + User + ";password=" + Password + ""; 
       MySqlConnection mySqlConnection = new MySqlConnection(connectionString); 
       mySqlConnection.Open(); 

       string Query = "load data local infile" + " " + "'" + FixFilePath + "'" + " " + "into table" + " " + Table + " FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY" + " " + c + d; 

       MySqlCommand cmd = new MySqlCommand(Query, mySqlConnection); 

       cmd.ExecuteNonQuery(); 

      } 

      catch (Exception ex) 
      { 
       MessageBox.Show(ex.Message); 
      } 
     }

Vous devez échapper à la double citation omble chevalier en utilisant \: "\""

string Query = "load data local infile" + " " + "'" + Filename + "'" + " " + "into table" + " " + Table + "' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES";

Ceci est la méthode complète.

public static void MySqlCSVImport(string Filename, string Table, string Server, string Database, string User, string Password) 
     { 
      try 
      { 
       //enclosed by '"' 
       string connectionString = "server=" + Server + ";database=" + Database + ";User Id=" + User + ";password=" + Password + ""; 
       MySqlConnection mySqlConnection = new MySqlConnection(connectionString); 
       mySqlConnection.Open(); 

       string Query = "load data local infile" + " " + "'" + Filename + "'" + " " + "into table" + " " + Table + "' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES"; 

       MySqlCommand cmd = new MySqlCommand(Query, mySqlConnection); 

       cmd.ExecuteNonQuery(); 

      } 

      catch (Exception ex) 
      { 
       MessageBox.Show(ex.Message); 
      } 
     }
