C#如何取oracle系统时间????

[x4177c]

我想这样取oracle的系统时间
string myConnString = "user id=newhis45;datasource=oraback;password=his";
con = new OracleConnection(myConnString);
comm = con.CreateCommand();
con.Open();
this.comm.CommandText = "select sysdate time from dual";
reader = comm.ExecuteReader();
this.textBox1.Text = reader.GetOracleDateTime(0).ToString();

可是不行！请问如何做才正确？？？？？

this.comm.CommandText = "select sysdate from dual";

改成这句:this.comm.CommandText = "select sysdate from dual";
也不行啊，，，我试了，

啊，没错，，我忘了reader.read();了，，，，多谢各位！！！！可以结了！

应该是这样的：

string myConnString = "user id=newhis45;datasource=oraback;password=his";
con = new OracleConnection(myConnString);
comm = con.CreateCommand();
con.Open();
this.comm.CommandText = "select sysdate time from dual";
reader = comm.ExecuteReader();
reader.Read();
this.textBox1.Text = reader.GetOracleDateTime(0).ToString();
