的Java與C＃ - CallableStatement的轉換

Question

您好我想了解如何將Java代碼轉換爲C＃，我讀了關於Java的一些教程，但我不覺得在如何代碼此行翻譯方式：

CallableStatement cstmt = con.prepareCall("?=CALL 
cstmt.registerOutParameter(1, Types.JAVA_OBJECT); 
cstmt.execute(); 
ResultSet rs = (ResultSet) cstmt.getObject(1); 

我試穿

CUBRIDConnection con = new CUBRIDConnection(ConnectionString); 
    CUBRIDCommand com = new CUBRIDCommand(); 
    com.CommandType = CommandType.StoredProcedure; 
    com.Connection = con; 
    com.CommandText = "call mySP();"; 
    com.Parameters.Add("?=p", CUBRIDDataType.CCI_U_TYPE_RESULTSET).Direction = 
     ParameterDirection.Output; 
    con.Open(); 
    DbDataReader df = com.ExecuteReader(CommandBehavior.SingleResult); 
    //some stuff 
    con.Close(); 

這個不行，我該怎麼翻譯呢？

Answer 1

試試這個

SqlConnection con = new SqlConnection("your connection string"); 
    SqlCommand com = new SqlCommand(); 
    com.CommandType = CommandType.StoredProcedure; 
    com.Connection = con; 
    com.CommandText = "yourstoredprocedurename"; //no paranthesis or call key word just procedure name 
    SqlParameter parameter = new SqlParameter("yourparametername", SqlDbType.Binary); //just parameter name no questionmark 
    parameter.Direction= ParameterDirection.Output; 
    com.Parameters.Add(parameter); 
    con.Open(); 
    var df = com.ExecuteReader(CommandBehavior.SingleResult); 
    //some stuff 
    con.Close(); 

Answer 2

我提出以下線，可以改進，以幫助它的工作：

SqlConnection con = new SqlConnection("ValidConnectionString");  

com.CommandText = "storedProcedureName"; // You need to give the command the actual SP name, call mySP(); is invalid. 

com.Parameters.Add("@ParameterName", SqlDbType.Binary).Direction = ParameterDirection.Output; // Parameters are usually prefixed with @ParameterName (some people omit the @) however this is preference amongst developers. 

注意：您與您的connectionString取代「ValidConnectionString」（除非ConnectionString是持有這些信息的變量）。如果不是，則連接字符串如下所示：Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;這將連接到SQL Server 2008數據庫。對於其他的連接字符串，看下面的網站：

我解決使用下面的例。
