Method to edit existing values

[thepwrtank18]

Here is my code:

document = NbtDocument.LoadDocument("level.dat");
root = document.DocumentRoot;
root.Name = "Data";
visibleVersion = (TagCompound)root.Value.Add("Version", TagType.Compound); // error here
visibleVersion.Value.Add("Id", (int) 2709);
visibleVersion.Value.Add("Name", (string) "21w15a");
File.Move("level.dat", "level.bak");
document.Save("level.dat");

I've noticed that when trying to run it, it says "Version" already exists, which it does. Is it possible to edit existing values, and if so, how?

Fixed it by adding this before adding visibleVersion:

root.Value.Remove("Version");

and this before the addition of values:

visibleVersion.Value.Remove("Id");
visibleVersion.Value.Remove("Name");

However, then it only saves what I edited.

Hello,

Apologies for the delay in responding. The Value property of a TagCompound has an indexer for accessing the child items for editing.

If you know the type up-front, you can cast it and set the value of the child

((TagInt)visibleVersion["Id"]).Value = 2709;

If you don't know the type, you can call SetValue, although this boxes primitives such as integers.

visibleVersion["Id"].SetValue(2709);

How would I get visibleVersion to exist without deleting it, then re-creating it?

Nevermind, I think I found it.

root.GetCompound("version")
