    copied!<p>I was wondering if you could look at my code and see where I have gone wrong. Basically, I have created an object of type "UserFile"(my own object type) and am creating 2 instances of it and within the constructor of that object, I am calling a static class method. All goes well for them except the second instance overwrites the first one after the object constructor is called. I have stepped through the program and am thoroughly confused. I get the feeling im missing something very obvious here.</p> <p><strong>Here is the button on the form that creates the instances</strong></p> <pre><code> private void btnCompare_Click(object sender, EventArgs e) { if (lstFiles.CheckedItems.Count == 2) { file1 = new UserFile(((FileLocation)lstFiles.CheckedItems[0]).filePath); file2 = new UserFile(((FileLocation)lstFiles.CheckedItems[1]).filePath); } } </code></pre> <p><strong>Here is the UserFile class with constructor</strong></p> <pre><code>public class UserFile { public Dictionary&lt;int,Individual&gt; fileIndividuals; public Dictionary&lt;int, Family&gt; fileFamilies; public Header fileHead; public UserFile(string _dir) { fileIndividuals = new Dictionary&lt;int, Individual&gt;(); fileFamilies = new Dictionary&lt;int, Family&gt;(); fileHead = new Header(); ReadFromFile.Read(_dir); fileIndividuals = ReadFromFile.individuals; fileFamilies = ReadFromFile.families; fileHead = ReadFromFile.head; } } </code></pre> <p><strong>Here is the ReadFromFile method called by the UserFile class</strong></p> <pre><code>static class ReadFromFile { public static string filename = ""; public static Header head; public static Individual individual; public static Dictionary&lt;int, Individual&gt; individuals = new Dictionary&lt;int, Individual&gt;(); public static Family family; public static Dictionary&lt;int, Family&gt; families = new Dictionary&lt;int, Family&gt;(); public static GedcomRecordEnum currentRecord = GedcomRecordEnum.None; public static GedcomSubRecordEnum currentFirstLvlRecord = GedcomSubRecordEnum.None; public static GedcomSecondLevelEnum currentSecondLvlRecord = GedcomSecondLevelEnum.None; static public void Read(string fileName) { individuals.Clear(); families.Clear(); head = null; if (File.Exists(fileName)) { filename = fileName; StreamReader reader = new StreamReader(fileName); while (!reader.EndOfStream) { string currentLine = reader.ReadLine(); Match m = Regex.Match(currentLine, "(?&lt;index&gt;[0-9]) (?&lt;keyword&gt;[A-Z_@0-9]+)(?: *)(?&lt;detail&gt;.*)"); string debug = m.Groups["index"].ToString(); switch (m.Groups["index"].ToString()) { case "0": ProcessRootLevel(m.Groups["keyword"].ToString()); break; case "1": ProcessLevel1(m.Groups["keyword"].ToString(), m.Groups["detail"].ToString()); break; case "2": ProcessLevel2(m.Groups["keyword"].ToString(), m.Groups["detail"].ToString()); break; case "3": ProcessLevel3(m.Groups["keyword"].ToString(), m.Groups["detail"].ToString()); break; } } reader.Close(); } } } </code></pre>
