What are you doing with this Xml that you need to read it into a string? Read it into an XmlTextReader or an XmlDom to do something useful with it. XmlReader will read only a chunk at a time so it's very memory efficient but parsing is a bit difficult.

There is no reason that I can think of to load Xml into a string.

>lcXml is defined as a String. lcStreamReader is containing a dataset which has been converted into a XML and then to it. At that point, I already changed the code to use a string builder approach instead of lcXml. With the lcXml, this is giving me an OutOfMemory exception. I have about 7000 records which contain a lot of fields in that dataset. If I have a little less than that, I am not running into the OutOfMemory exception. With the change of code, I did not have the time to test if this will help so far.
