Empty string coming from web services

[NormD]

I have a web service method that returns a dataset. A field in a datatable in
the dataset in the server has 120 chars long empty string as it's value. When
this comes back to client the field value is trimmed. Why is this happening?
Any help to get around this is greatly appreciated.

Hello,

This is a known issue. A DataSet will be converted into XML string before
sending from web service. For a empty string in a dataset, it may be
converted as following ("name" is the field name):

<name> </name>

On client side, it will be recognize as a null string.

Normally, " " make same sense with "". If you really a empty string with
defined length, you may add a column in your dataset with base64Binary type
and convert the string into this column. On client side, you need to
convert it back to string.

Is there any other way of handling this? As it's, I can't change how the
program executes since it's pretty generic.

The Empty string has been "compressed" on server side. If we cannot change
the server side's code, it will be impossible to get the actual value on
client side.
