I am SORRY! It is my mistake.
I set the Unicode property to true in the control "OracleConnection" before. In fact, I should be set this property in the code. It is OK now!
Thank you very much!

connection.Close();
connection.ConnectionString = "";
connection.Unicode = true;
connection.UserId = tbUser.Text;
connection.Password = tbPassword.Text;
connection.Port = Convert.ToInt32(tbPort.Text);
connection.Server = tbHost.Text;
connection.Sid = tbDatabase.Text;

I installed the newest version (5.25.39).
But I still got the same error when I change the regional to Chinese (PRC).
If I set the regional to English (United States), it can open the database, but it can not display Chinese character properly.
I tested the connection in many servers. It seems that the servers' OS version (Chinese or English) is not important. The program can connect Chinese XP/2003 and English XP/2003 if I set the device's regional to English (United States). But if I set the regional to Chinese (PRC), it will throw a "PlatformNotSupportedException" exception.

Could you tell me when will the fixed verision release?

int codePage = Encoding.Default.CodePage; //codePage = 936
string encodingName = Encoding.GetEncoding(codePage).ToString(); //encodingName = System.Text.CodePageEncoding

Yes,I am using non-localized device. My device's OS is WM6.1(Chinese Version).
My computer's OS is Windows XP SP3(English), but I already changed the setting to Chinese(PRC) in Regional and Language Options.
My Oracle version is 10.2.0.3, and nls_language is SIMPLIFIED CHINESE.
I just compiled the sample project in VS2008 and try to connect my oracle database, I did not modify any source code.
