Unicode Property (OracleConnection)
Gets or sets a value indicating whether the UTF16 charset will be used.
public bool Unicode {get; set;}
'Declaration
Public Property Unicode As Boolean
Property Value
true, if client charset UTF16 is used;
false, if default client charset is used. The default value is
false.
The following two functions demonstrate how to use
Unicode property to implement charset-safe string transfer.
public void UploadString(OracleConnection myConnection)
{
myConnection.Unicode = true;
OracleCommand myCommand = new OracleCommand("INSERT INTO Test.TextBlocks (BlockID, BlockName, BlockContent) VALUES(1,'First',:BlockText)", myConnection);
myCommand.Parameters.Add("BlockText",OracleDbType.VarChar,50).Value = "Place here some text that requires Unicode support.";
myConnection.Open();
try
{
Console.WriteLine(myCommand.ExecuteNonQuery()+" rows affected.");
}
finally
{
myConnection.Close();
}
}
