怎么在C#(.NET2.0)对VPF6.0进行增删改（使用odbc)

//自己配置的DSN连接没有问题
string ConnectionString = "Dsn=Kaiser";
using (OdbcConnection tempCon = new OdbcConnection())
{
   tempCon.ConnectionString = ConnectionString;
   tempCon.Open();
   //可以正常连接
   Console.WriteLine(tempCon.State.ToString());
   OdbcCommand tempCmd = tempCon.CreateCommand();
   //错误出在这里，不知道如何配置输入参数（以及输入参数的前缀)
   tempCmd.CommandText = "insert into Stu_BasicInfo(StuID, StuName) values(@StuID, @StuName)";
   tempCmd.Parameters.Add("@StuID", OdbcType.VarChar, 36, "StuID").Value = Guid.NewGuid().ToString(); 
   tempCmd.Parameters.Add("@StuName", OdbcType.VarChar, 200, "StuName").Value = "Kaiser"; 
   tempCmd.ExecuteNonQuery();
}
