[c#]代码库public static void Read_VoteBasic(int vbid, out DataTable dt)

{

dt = new DataTable();

try

{

using (SqlConnection conn = new SqlConnection(strConn))

{

SqlCommand cmd = new SqlCommand("Read_VoteBasic", conn);

cmd.CommandType = CommandType.StoredProcedure;

SqlParameter spvoteid = new SqlParameter("@pVoteID", SqlDbType.Int);

spvoteid.Value = vbid;

cmd.Parameters.Add(spvoteid);

conn.Open();

using (SqlDataAdapter sda = new SqlDataAdapter())

{

sda.SelectCommand = cmd;

sda.Fill(dt);

}

conn.Close();

}

}

catch (Exception)

{

dt = null;

//throw;

}

}

尽量避免使用out
