Crystal easy table calls WebService of C which returns the application analysis of the data set

1. Crystal easy table cannot recognize DataTable or DataSet data type returned by WS interface, and will prompt "URL cannot be loaded"

3. C# calls Package of Oracle and returns a list of data

2. It has been verified that string is acceptable. If you need to return a list of data, you need to use an array to return.
