POHow do I create a static array containing my custom class?
text
Body
copied!<p>I have a method that returns an array of custom class objects that are created by parsing a text file. At the moment every time I use it I am rereading the file which isn't very efficient.</p> <p>What I wat to do is create an array containing the objects when the page loads and store them in an array which can then be used later.</p> <p>The method is:</p> <pre><code>public Album[] readArray(string sTextFilePath) { string[] allLines = File.ReadAllLines(Server.MapPath(sTextFilePath)); Album[] Albums = new Album[allLines.Length]; for (int i = 0; i < allLines.Length; i++) { string[] lineSplit = allLines[i].Split(','); Albums[i] = new Album(); Albums[i].ID = Convert.ToInt32(lineSplit[0]); Albums[i].title = lineSplit[1]; Albums[i].keyName = lineSplit[2]; } return Albums; } </code></pre> <p>and the class is simple, just:</p> <pre><code> public class Album { public int ID { get; set; } public string title { get; set; } public string keyName { get; set; } } </code></pre> <p>I thought I could create the static object using something like:</p> <pre><code>static Album myAlbums[] = readArray("Albums.txt"); </code></pre> <p>but I am getting the following error:</p> <p><strong>A field initializer cannot reference the nonstatic field, method, or property 'B2M._Default.readArray(string)'</strong></p> <p>I am new to C# so this is probably something dumb. (Feel free to poke fun in my general direction if this is the case!)</p> <p>Thanks in advance for any assistance,</p> <p>Ben</p>
