Aleks has got the straight-up answer - I just wanted to contribute something from another angle.

This code is fine from an academic, just learning the concepts point of view.

But if you're looking to translate this into something for business dev, you should get in the habit of structuring it like:

<ul>
<li>Develop a Planet class</li>
<li>Have a function that returns a Planet from a source text line</li>
<li>Have a function that displays a Planet how you intend it to be
displayed.</li>
</ul>

There are a lot of reasons for this, but the big one is that you'll have reusable, flexible code (look at the function you're writing right now - how likely is it that you'll be able to reuse it down the line for something else?) If you're interested, look up some info on SRP (Single Responsibility Principle) to get more info on this concept.

This is a translated version of your code:

<pre><code> static void Main(string[] args)
 {
 string planetsDBStr = "1 Mercury Gray \n"
 + "2 Venus Yellow \n"
 + "3 Earth Blue \n"
 + "4 Mars Red \n";

 List&lt;Planet&gt; planets = GetPlanetsFromDBString(planetsDBStr);

 foreach (Planet p in planets.OrderBy(x =&gt; x.color))
 {
 Console.WriteLine(p.ToString());
 }
 Console.ReadKey();

 }

 private static List&lt;Planet&gt; GetPlanetsFromDBString(string dbString)
 {
 List&lt;Planet&gt; retVal = new List&lt;Planet&gt;();
 string[] lines = dbString.Split("\n".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
 foreach (string line in lines)
 retVal.Add(new Planet(line));
 return retVal;
 }

 public class Planet
 {
 public int orderInSystem;
 public string name;
 public string color;
 public Planet(string databaseTextLine)
 {
 string[] parts = databaseTextLine.Split(' ');
 this.orderInSystem = int.Parse(parts[0]);
 this.name = parts[1];
 this.color = parts[2];
 }
 public override string ToString()
 {
 return orderInSystem + " " + name + " " + color;
 }
 }
</code></pre>

EDIT: Fixed some formatting issues

I have a string with numbers, words, and linebreaks that I split into an Array.

If I run <code>Array.Sort(lines)</code> it will sort the Array numerically by Column 1, <code>Number</code>.

How can I instead sort the Array alphabetically by Column 3, <code>Color</code>?

<hr>

Note: They are not real columns, just spaces separating the words.

I cannot modify the string to change the results.

<hr>

<pre><code>| Number | Name | Color |
|------------|------------|------------|
| 1 | Mercury | Gray |
| 2 | Venus | Yellow |
| 3 | Earth | Blue |
| 4 | Mars | Red |
</code></pre>

<hr>

C#

Example: <a href="http://rextester.com/LSP53065" rel="nofollow noreferrer">http://rextester.com/LSP53065</a>

<pre><code>string planets = "1 Mercury Gray\n"
 + "2 Venus Yellow\n"
 + "3 Earth Blue\n"
 + "4 Mars Red\n";


// Split String into Array by LineBreak
string[] lines = planets.Split(new string[] { "\n" }, StringSplitOptions.None);


// Sort
Array.Sort(lines);


// Result
foreach(var line in lines)
{
 Console.WriteLine(line.ToString());
}
</code></pre>

<hr>

Desired Sorted Array Result

<pre><code>3 Earth Blue
1 Mercury Gray
4 Mars Red
2 Venus Yellow
</code></pre>

我有一个字符串，其中包含数字、单词和换行符，我将其拆分为数组。如果我运行Array.Sort(lines)，它将按第1列Number对数组进行数字排序。如何将数组按第3列( Color )按字母顺序排序？注意:它们不是真实的列，只是分隔单词的空格。我无法修改字符串以更改结果。| Number     | Name   ...
