# Note
```csharp
public sealed class Note
```
Namespace `SharpCell` ยท package `SharpCell`
A note on a cell: Excel's Insert Note (called a comment before Excel 365), shown in a box beside the cell, by default only while the pointer rests on it. Excel's threaded comments, with replies, are not notes; a file's own are kept when it is saved.
## Constructors
### Note(string, string)
```csharp
public Note(string text, string? author = null)
```
A note with `text`, written by `author`.
**Parameters**
- `text`: The note's text. Excel puts the author's name and a colon on the first line of a note it makes; SharpCell writes only the text it is given.
- `author`: Who wrote the note, or null for nobody. Excel shows it in the status bar while the pointer rests on the cell.
**Exceptions**
- `ArgumentNullException`: The text is null.
- `ArgumentException`: The text is longer than 32,767 characters, as Excel allows.
## Properties
### Author
```csharp
public string? Author { get; }
```
Who wrote the note, or null for nobody.
### IsVisible
```csharp
public bool IsVisible { get; init; }
```
Whether the note is always shown, as Excel's Show/Hide Note makes it; otherwise it is shown only while the pointer rests on its cell.
### Text
```csharp
public string Text { get; }
```
The text, with `\n` between lines.
## Methods
### Equals(Note)
```csharp
public bool Equals(Note? other)
```
Whether the other note has the same text, author and visibility, compared ordinally.
### Equals(object)
```csharp
public override bool Equals(object? obj)
```
Whether `obj` is the same note.
### GetHashCode()
```csharp
public override int GetHashCode()
```
A hash code consistent with [Note.Equals](SharpCell.Note.md#equals-note).
### ToString()
```csharp
public override string ToString()
```
The text.
