i had maked a method of get data like this

C#

public List<datalist7> getdata(string id)
{
  SqlConnection con = new SqlConnection(@"Data Source=saba-PC;Initial Catalog=bcounts;Integrated Security=True");
  con.Open();
  SqlCommand cmd = new SqlCommand("Select Compcode,Acct_sub0,Acct_Desc from GI_sub0 where Compcode='" + id + "'", con);
  SqlDataReader rdr = cmd.ExecuteReader();
  List<datalist7> data = new List<datalist7>();
  if (rdr.HasRows)
  {
    // while (rdr.Read())
    //  data.Add(new dataclass7(rdr.GetString(0), rdr.GetString(1), rdr.GetString(2)));
  }
  con.Close();
  return data;
}
        
[DataContract]
public class datalist7
{
  [DataMember]
  public string val1 { get; set; }
  [DataMember]
  public string val2 { get; set; }
  [DataMember]
  public string val3 { get; set; }
  [DataMember]
  public string val4 { get; set; }
  [DataMember]
  public string val5 { get; set; }
  [DataMember]
  public string val6 { get; set; }
  [DataMember]
  public string val7 { get; set; }
  public datalist7(string v1, string v2, string v3, string v4, string v5, string v6, string v7)
  {
    val1 = v1;
    val2 = v2;
    val3 = v3;
    val4 = v4;
    val5 = v5;
    val6 = v6;
    val7 = v7;

Note that you have comment the item adding code of your service

C#

if (rdr.HasRows)
{
  // while (rdr.Read())
  //  data.Add(new dataclass7(rdr.GetString(0), rdr.GetString(1), rdr.GetString(2)));
}

if this is actual code of service you will not get any results.

it should be soemthing like below

C#

if (rdr.HasRows)
{
  while (rdr.Read())
    data.Add(new dataclass7(rdr.GetString(0), rdr.GetString(1), rdr.GetString(2), "", "", "", ""));
}

otherwise your service code and WcfTestClient application working fine. As per WcfTestClient response, there is no matching records found for '001' go to sql server and run below statement

SQL

Select Compcode,Acct_sub0,Acct_Desc from GI_sub0 where Compcode='001'

you will not get any records for sure.
