存储过程无参数问题

ALTER PROCEDURE get_user //存储过程

AS
select name1 from T_user
RETURN

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("get_user",conn);
cmd.CommandType = CommandType.StoredProcedure;
conn.Open();
SqlDataReader sdr = cmd.ExecuteReader();

if(sdr.Read())
{

TextBox1.Text = sdr[0].ToString();
}


}
} //我的代码，我的数据库有很多数据，为什么只能读出，第一条数据？？求高手，给详细答案

应循环读取sdr,
.....
SqlDataReader sdr = cmd.ExecuteReader();
while( sdr.Read())
{
Response.Write(sdr[0].ToString()+"<br />");

}

 public static DataTable ReturnDataTable(string cmdtext, CommandType ct)
        {
            DataTable dt = new DataTable();
            cmd = new SqlCommand(cmdtext, GetConn());
            cmd.CommandType = CommandType.Text;
            SqlDataReader dr = null;
            using (dr = cmd.ExecuteReader(CommandBehavior.CloseConnection))
            {
                dt.Load(dr);
            }
            return dt;
        }

调用ReturnDataTable（sql语句或者存储过程Name）

if(sdr.Read())
读了一条就over了，用while

while(sdr.Read())
{
this.TextBox1.Text += sdr["name1"];//得用字符串的相加，防止结果
