String Limitations

[HarisMasood]

Hi All
I am reading a XML File and storing its contents to a string variable using stream reader.The problem I encountered is that most of data is lost. Is there any way to store whole file in a string variable. I have to send this XML File data to extrenal webservice whose web method accept only string.I would appreciate if anyone help me in this regard.

Which language are you using to read the XML?

How many characters does your XML file typically contain? I can't remember the exact upper limit of a string (and it can vary between languages) but it's pretty massive.
