i have a web service returning a big xml, it works fine with the default test
page on .asmx page. but when i built a client using the proxy class,and used
it to retrieve the XML and tried to print it out in a text box, got error:
hexadecimal value 0x00, is an invalid character. Line 1, position 12345.
any idea what is wrong? i googled and didn't find much helpful information
including the one below

thanks a bunch

it seems that the xml string have a 0x00 character at the end which needs to
be got rid of ....
like this:
thisString.Trim(Convert.ToChar(0));

test

isn't that a null value and thus different from null string, so u have to treat
it separately and specially?
