How to set up XML serialization?

Question

.NET

Help to configure XML serialization. Throws this exception:

Unhandled exception of type 'System.InvalidOperationException' in System.Xml.dll
Additional information: There is an error in the XML document (2, 2).

I would also be grateful for any comments on the code.

Answer 1

1. XML (2, 2) is almost 80% wrong type conversion. That is, you are trying to deserialize an object into the wrong type. Or type to list
2. No root element.
Try to serialize/deserialize normal.
Write the encoding in XML, encoding="utf-8".
Write attributes (depending on the version) in the class

[XmlElement]
[XmlRoot("...")]
там еще что-то с array есть.

Catch the exception in catch and see what is written there. There are more details sometimes

Answer 2

Additional information: There is an error in the XML document (2, 2).

It probably means " - " characters before top-level nodes. If there is no solid justification for their presence, remove them.

Answer 3

In fact, they are not in the code, it just happened to be transferred to the toaster

Answer 4

And if you make a special insertion of XML as C# code? Will serialization work?
