I want to get the Value of the Tag，what should I do？

[NingLiu1998]

This is a great open source! But I encountered some problems in the process of using, I don't know how to solve this problem, my technical level is relatively low

I can't find Value in "Tag", how can I get this value

[ForeverZer0]

The Value property is defined within the Tag<T> class, which inherits from the Tag class. Both of these classes can be found in the Tag.cs file, the Tag<T> class is found near the bottom of the file.

Practically speaking, all the defined NBT tag types inherit from Tag<T>, and not Tag directly, but this gives them a common base that does not require a generic, which is often cumbersome with statically-typed languages and where T might not be known or even cared about.

I hope this helps.

十分感谢！！！ 用var用习惯了导致的问题，我知道该怎么做了

When parsing arbitrary strings into NBT, the returned object is an abstract Tag, which will need to be inspected and cast to the more refined tag type that it actually is, as C# is a statically-typed language. There are numerous ways to do this, though the "best" way depends on your needs. Here are some common methods of doing so:

---

Pattern matching:

if (abstractTag is StringTag stringTag)
    string value = stringTag.Value;

This method can also be used in a switch expression.

---

Check the Type property, which contains a TagType enumeration value. You could then use a switch or if expression to cast it directly to the matching type.

TagType enumValue = tag.Type;
switch (enumValue)
{
   case (TagType.String)
        StringTag stringTag = (StringTag) tag;
        // ...
}

---

If you have your type is already known ahead of time or only one specific type of tag is acceptable for your use-case, you could just wrap it in a try/catch and "blindly" cast it to that type, and adapt your scenario on whether the exception is thrown or not. This is going to be highly case-dependent, and really only appropriate for very specific scenarios, so I wouldn't generally recommend it.
