How to parse very huge XML Files in C#? [duplicate]

Answer 1

You need to use XmlReader

It represents a reader that provides fast, noncached, forward-only access to XML data. Won't load all the data into memory, supposed to be used with large sets of data. Other built in.NET solutions keep the full generated object graph.

Answer 2

Use XML reader instead of XML dom. XML dom stores the whole file in memory which is totally useless:
