# Log Levels
Welcome to Log Levels on Exercism's C# Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
If you get stuck on the exercise, check out `HINTS.md`, but try and solve it without using those first :)
## Introduction
## Strings
A `string` in C# is an object that represents immutable text as a sequence of Unicode characters (letters, digits, punctuation, etc.). Double quotes are used to define a `string` instance:
```csharp
string fruit = "Apple";
```
Strings are manipulated by calling the string's methods. Once a string has been constructed, its value can never change. Any methods that appear to modify a string will actually return a new string.
Multiple strings can be concatenated (added) together. The simplest way to achieve this is by using the `+` operator.
```csharp
string name = "Jane";
"Hello " + name + "!";
// => "Hello Jane!"
```
For any string formatting more complex than simple concatenation, string interpolation is preferred. To use interpolation in a string, prefix it with the dollar (`$`) symbol. Then you can use curly braces (`{}`) to access any variables inside your string.
```csharp
string name = "Jane";
$"Hello {name}!";
// => "Hello Jane!"
```
## Instructions
In this exercise you'll be processing log-lines.
Each log line is a string formatted as follows: `"[]: "`.
There are three different log levels:
- `INFO`
- `WARNING`
- `ERROR`
You have three tasks, each of which will take a log line and ask you to do something with it.
## 1. Get message from a log line
Implement the (_static_) `LogLine.Message()` method to return a log line's message:
```csharp
LogLine.Message("[ERROR]: Invalid operation")
// => "Invalid operation"
```
Any leading or trailing white space should be removed:
```csharp
LogLine.Message("[WARNING]: Disk almost full\r\n")
// => "Disk almost full"
```
## 2. Get log level from a log line
Implement the (_static_) `LogLine.LogLevel()` method to return a log line's log level, which should be returned in lowercase:
```csharp
LogLine.LogLevel("[ERROR]: Invalid operation")
// => "error"
```
## 3. Reformat a log line
Implement the (_static_) `LogLine.Reformat()` method that reformats the log line, putting the message first and the log level after it in parentheses:
```csharp
LogLine.Reformat("[INFO]: Operation completed")
// => "Operation completed (info)"
```
