Parse style attribute collection using linq

Question

I want to parse an SVG style attribute, which is just a delimited string, e.g.

"fill:#e2b126;stroke:#010101;stroke-width:0.3177;stroke-miterlimit:10"

into a Dictionary<string,string> so that I can perform some processing on it.

Here's what I have, which does the job, but I'd like to make it neater using a linq projection, just can't seem to get the syntax. I tried using .Select().ToDictionary etc, but no joy. Thanks:

string attributes = "fill:#e2b126;stroke:#010101;stroke-width:0.3177;stroke-miterlimit:10";
var pairs = attributes.Split(';').ToList();
var dic = new Dictionary<string, string>();
pairs.ForEach(p =>
    {
        var pair = p.Split(':');
        dic.Add(pair[0], pair[1]);
    });
 foreach (var k in dic.Keys)
 {
       Console.WriteLine(k + " " + dic[k]);
 }

Expected output:

fill #e2b126 
stroke #010101 
stroke-width 0.3177 
stroke-miterlimit 10

Answer 1

Try the following

string attributes = "fill:#e2b126;stroke:#010101;stroke-width:0.3177;stroke-miterlimit:10";
var map = attributes
  .Split(new []{';'}, StringSplitOptions.RemoveEmptyEntries)
  .Select(x => x.Split(new []{':'}, StringSplitOptions.RemoveEmptyEntries))
  .ToDictionary(p => p[0], p => p[1]);

Breakdown

The first Split call will return an array of String values where every entry is in the key:value format. The following Select call will convert every one of those entries into a string[] where the first element is the key and the second is the value. The ToDictionary call just expressly performs this mapping
