Returning DataTables in WCF/.NET

Question

I have a WCF service from which I want to return a DataTable. I know that this is often a highly-debated topic, as far as whether or not returning DataTables is a good pract

Answer 1

There are 3 reason for failed return type as datatable in WCF services

• You have to specify data table name like:

  MyTable=new DataTable("tableName");
  

• When you are adding reference on client side of WCF service select reusable dll system.data

• Specify attribute on datatable member variable like

  [DataMember]
  public DataTable MyTable{ get; set; }
